This standard extends on electrotechnical products (further
products) economic appointment and for the export which list is
resulted in the appendix 2, and establishes the general technical
requirements on firmness of products to influence of climatic
external influencing factors (further - climatic factors of an
environment), concretising requirements of GOST 15150 with
reference to the products specified above.
The terms applied in this standard, and their explanatories are
resulted in the appendix 3.
1. The list and rating values of climatic factors of an
environment at operation for kinds of climatic modifications in
accordance with GOST 15150 establish according to the table and
subitem 2-13.
In technical projects (further - ), standards and specifications
on concrete series or types of products (further in standards and
THAT on products), depending on their design features and the shown
requirements to group of products or to concrete products, spend
additional restriction of used kinds of climatic modifications.
According to economic and a technical feasibility manufacturing of
the products meeting requirements of several kinds of climatic
modifications, specified in this standard is recommended.
In , standards and THAT on products specify a climatic
modification kind. In the specifications and technical
documentation (reference documents) of kind on the products
intended only for concrete object, the requirement on firmness of
the product planned to working out, if necessary, specify also in
the form of values of climatic factors.
Designation of a kind of a climatic modification enter into a
symbol of type (mark) of a product according to GOST 15150, section
2, thus specify group of the lowered pressure. In , standards and
THAT on products it is supposed to specify in addition height above
sea level or pressure.
The note. In this standard at instructions of a kind of a
climatic modification in brackets the serial number under the table
is specified.2. The kinds of climatic modifications specified in
subitem 2, use only for the products specified in these points.
2.1. Kinds of climatic modifications: 2,5 ** (25); 1 ** (56);
2.1 ** (57); 4 ** (58); 1 ** (65); 2.1 ** (66); 4 ** (67); 2.1 **
(90); 2.1 ** (96); 5.1 ** (97); 2.1 ** (99) use for the products
specially intended for application as built in elements in heated
complete electrotechnical and radio-electronic products if it is
caused by specificity of these complete products.
2.2. A kind of climatic modification 3.1 ** (26) use for the
products intended for placing on engines of the ships on an air
cushion and .
2.3. A kind of climatic modification 4 ** (27) use for the
products intended for installation on engines of all kinds of
courts (ships).
2.4. A kind of climatic modification 2 ** (71) use for the
products intended for installation in motorno-transmissionnyh
branches of some mobile installations if it is caused by
specificity of these installations.
3. Requirements on limiting working values of temperature of air
establish according to GOST 15150, section 4. In particular, if for
products in the reference document the indicator of probability of
non-failure operation 0,9999 and more for service life more than 5
years to such products make demands on limiting working values of
temperature is established.
4. Products of kinds of climatic modifications 1 (21) and 4 (24)
produce in a uniform design for two effective temperatures
specified in the table with instructions of technical parametres of
products at both values of temperature, thus nominal parametres of
products should be calculated for temperature 45 .
5. If for products it is necessary to establish distinct from
specified in the table of value of climatic factors, they are
established according to requirements of GOST 15150, by section 5,
6, 8, 9, and also section 3 (regarding cooling by water, work in
water, soil, in tight volumes).
5.1. For the products intended for application as built in
elements in heated complete products, the top working value of
temperature establish 55 if in standards and specifications on
products of concrete series and types others are not established
top working and (or) effective the values of temperature caused by
conditions of operation of these products in a complete
product.
6. Changes of temperature of air and value of temperature of
cooling water choose in accordance with GOST 15150, section 3.
Effective value of temperature of cooling water should correspond
to the top working value.
7. For products to which according to the table on firmness
demands are made to influence of a dust, ozone, sunlight, working
values of these climatic factors establish according to GOST 15150,
section 3.
8. Requirements to water influence show to products for which it
is specified in , according to GOST 14254.
9. Products to which according to the table demands on hoarfrost
influence are made, should maintain the appendix of nominal
electric pressure without breakdown or superficial overlapping at
loss on a product of hoarfrost with its subsequent thawing.
10. Requirements on working capacity of products at formation on
them of ice show (if it is established in , standards and THAT) to
products of executions At, , M, the OHM, the Island In a category
1, and also to intended for operation under a canopy to products of
the category 2, having open mobile parts and (or) open disconnected
contacts, in particular, to corresponding products on pressure St.
1000 Century
11. It is supposed (if it is established in standards and THAT
on products or under the permission of developers or manufacturers
of products) constantly to maintain products without change of
their resource (or service life) at following values of an ambient
temperature.
11.1. At the temperature exceeding effective temperature
established in this standard. In this case it is necessary to
reduce loading of products so that specified in standards and THAT
on products temperatures supposed excess have been reduced by the
size equal to a difference between actual and specified in this
standard effective temperatures, and the difference should be
approximated towards increase to number, multiple 5. Thus, if the
specified difference exceeds 10 , it is necessary to be convinced
that products can work at actual temperature of those knots and
details which at work of products at in standards and THAT on
products values of temperature of an environment are not exposed to
the heatings close to extremely supposed. In particular, for
products on pressure 3 and above it can appear necessary to
consider decrease in electric durability firm, liquid and gaseous
(including air) materials.
11.2. At temperature less than effective temperature established
in this standard. In this case it is supposed to increase loading
of products so that temperatures extremely supposed excess have
been increased by the size equal to a difference between specified
in this standard and actual effective in temperatures. Thus, if the
specified difference exceeds 10 for electric cars (except a turbo -
and hydrogenerators with length of the core to 2) or 20 for other
products, it is necessary to be convinced of an increase
admissibility temperatures, proceeding from a difference of factors
of thermal expansion of materials, speed of increase of temperature
of details at inclusion of products, temperature drops in products,
etc.
The note. The actual effective temperature is defined according
to GOST 15150, by section 6.
12. In the limits specified in the standard of ranges of
climatic factors, some values of the same factor can be established
at an establishment of requirements concerning separate technical
characteristics (for example, some values top and (or) effective
temperature at various resources or service life of products).
13. Requirements on firmness to climatic factors of an
environment for cables, wires, cords and tyres, and also for
brushes of electric cars, establish according to appendices 4 and
5.
14. Requirements on firmness to climatic factors of an
environment at transportation and storage establish in accordance
with GOST 15150 according to GOST 23216.

THE APPENDIX 4
The obligatoryESTABLISHMENT OF REQUIREMENTS ON FIRMNESS TO
CLIMATIC FACTORS OF THE ENVIRONMENT IN STANDARDS AND SPECIFICATIONS
ON CABLES, WIRES, CORDS AND TYRES AND TYPICAL FORMULATIONS
1. GENERAL PROVISIONS
1.1. The kind of a climatic modification of cables, wires
(except ), and tyres specify in the same formulations, as for other
electrotechnical products. If cables are intended for a lining in
soil, it in addition specify in the prologue or in section
Execution of products. For example: cables make a kind of a
climatic modification 1 in accordance with GOST 15150, and also for
a lining in soil.
At a choice of kinds climatic execution according to this
standard requirements in addition accept the following:
The cables intended for a lining in soil with an exit to
stationary electroinstallations or other electrotechnical products,
working on open air, carry to the kinds of climatic modifications
corresponding to categories 1 or 2 in accordance with GOST 15150
according to requirements of the standard on cable products;
Tyres not isolated, for air-lines of electricity transmissions
or communication carry wires to the kinds of a climatic
modification corresponding to a category 1;
Cords connecting for household appliances carry to the kinds of
climatic modifications corresponding, as a rule, to a category
4.
1.2. Conditions of operation of cables, wires (except ), cords
and tyres specify in the same formulations, as for other
electrotechnical products. In addition specify value of the bottom
temperature at operation in the formulation of item 1.3 of the
present appendix.
1.3. The bottom value of temperature at operation specify in the
following formulation: The bottom value of temperature at
operation: In the absence of deformations - a minus... ;
In the presence of deformations - a minus (plus)... , including
at installation and reinstallation (or a lining) - a minus (or
plus)... .
As deformations in the present point understand processes of a
bend, axial torsion, a stretching .
The bottom value of temperature for a case of absence of
deformations at operation choose the most rigid from among values,
this standard for the sake of appearances a climatic modification
specified according to item 1.1 of the present appendix. Thus, as a
rule, choose working values of temperature.2. RATIONING OF THE TOP
AND EFFECTIVE VALUES OF TEMPERATURE FOR CABLES, WIRES (EXCEPT ),
CORDS AND TYRES
2.1. For not heated cables, wires, cords and tyres normalise top
or () effective value of temperature of an environment.
2.2. For heated cables, wires, cords and the tyres intended for
work, as a rule, in normal conditions (for example, power cables),
normalise the top and effective values of temperature of an
environment and in case of need - values of temperature on a
vein.2.3. For heated cables, wires, cords and the tyres intended
according to item 5 of this standard for operation, as a rule, at
values of climatic factors, differing from established in the
table, in particular, in electrotechnical or radio-electronic
products (for example, for adjusting and assembly wires), instead
of value of temperature of an environment normalise top or ()
effective value of temperature of a vein for least an element of a
cable, a wire, a cord or the tyre.
2.4. At a choice of the top value of temperature of products for
kinds of the climatic modifications corresponding to a category 1,
consider requirements of GOST 15150 (section 3 regarding
temperature of surfaces, section 5 - regarding products in a
plastic cover).
2.5. As the heated understand cables, wires, cords, the tyres
intended for transfer to such capacity of an electromagnetic field
under which action excess of temperature of separate elements of a
product over environment temperature reaches 10 (With and more.3.
VALUES ADMISSIBLE LOADINGS ON CABLES, THE WIRE (EXCEPT ), CORDS AND
TYRES
3.1. For the effective values of temperature specified in this
standard for kinds of climatic modifications, corresponding to a
climatic modification At (temperature of air 40 ) or the
temperature of water or soil 25 ), accept sizes admissible loadings
which in Rules of the device of electroinstallations (PUE) or the
directories supposed when due hereunder for designing, are carried
to settlement temperature of air 25 With or temperature of water or
soil 15 (With.
3.2. If for any kind of a climatic modification specified in
this standard table the effective temperature differs from
specified for execution At in item 3.1 of the present appendix,
apply correction factors on temperature of soil, water or air.
For concrete values of a difference between demanded and
specified in item 3.1 effective values of temperature accept the
correction factors specified in PUE or directories, supposed when
due hereunder for designing, for the same values of a difference
between actual and settlement temperatures.
For example, if cables are intended for operation in the
conditions of 2 in accordance with GOST 15150 then demanded
effective value of temperature according to this standard table
(taking into account a footnote **) is equal 50 , and a difference
between demanded and specified in item 3.1 of the present appendix
effective value of temperature makes 10 (50 40 ). In this case
accept the correction factor specified in PUE for actual
temperature 35 (25 + 10 ).
3.3. If the actual temperature of an environment at long
operation of cables, wires, cords, tyres is known and differs from
25 for air or 15 for water and soil, accept correction factors on
the environment temperature, specified in PUE or the directories
supposed when due hereunder for designing.
The note. Requirements of the present section apply because of
necessity of combination of values of conditional temperatures of
an environment on which are based accepted for calculation of rated
loads of value maximum permissible temperatures of parts of
electrotechnical products and which have appeared unequal for cable
products and for the majority of other electrotechnical products
maintained in the same normal climatic conditions.
4. APPLICATION AND THE FORMULATION THE REQUIREMENT REGARDING
CLIMATIC FACTORS OF THE ENVIRONMENT AT OPERATION FOR WIRES
4.1. Climatic modifications and categories of placing do not
specify.
4.2. At an establishment of requirements on operation conditions
on this standard and GOST 15150 do not refer.
4.3. The top and effective values of temperature do not specify,
and specify a class to isolation, behind an exception the wires
specially intended for work in specific conditions (for example for
the wires intended for water-or electric motors, specify the top
and effective values of temperature, instead of a class to
isolation).
If to isolation of wires above class , instead of a class
specify some values of temperature and an isolation resource.
4.4. The bottom value of temperature at operation write down in
the following formulation: the Bottom value of temperature at
operation - a minus 60 .
The note. If on operation conditions it is required to specify
the bottom value of temperature differing from a minus 60 , at a
choice of this value 15150 (section 5) are guided by tab. 1 of this
standard and GOST. Thus, as a rule, choose the bottom working value
of temperature.
4.5. Other climatic factors do not normalise.THE APPENDIX 5 The
obligatoryESTABLISHMENT OF REQUIREMENTS TO BRUSHES FOR ELECTRIC
CARS REGARDING INFLUENCE OF CLIMATIC FACTORS OF THE ENVIRONMENT AND
TYPICAL FORMULATIONS
1. In standards and specifications on brushes for electric cars
of a condition of operation write down in the formulation specified
more low if according to subitem 2-5 of the present appendix it is
not required changes of this record:
Brushes for electric cars (further - brushes) are intended for
operation in the conditions of 2, 3 and 4 in accordance with GOST
15150.
Application of brushes in conditions, for other climatic
modifications, and also categories 1 and 5 in accordance with GOST
15150, make with the coordination of their application when due
hereunder between the organisation-holder of the original of the
design documentation (or the developer) electric cars and the
developer of brushes .
2. On occasion the coordination of application of brushes, for
other climatic modifications, can be spent with the consumer of
brushes. The requirement regarding the application coordination
does not extend on direct export deliveries if in the order
concrete marks of brushes are specified.
3. If the coordination of application of the brushes, provided
in item 1, is spent to the statement of standards or specifications
(or changes to these standards or specifications) on brushes in
standards or specifications on brushes specify all co-ordinated
conditions of operation for concrete types of electric cars.
4. If according to the documentation operating till the moment
of introduction of the given appendix, a brush of serial marks are
applied in products of tropical execution, the additional
coordination of application of brushes it is not required.
5. Regarding conditions of operation of brushes instead of the
top and effective value of temperature of an environment the top
and effective value of maximum permissible temperature of a brush
can be specified.
6. A designation of a kind of a climatic modification into a
designation of mark of a brush do not enter, in the accompanying
document specify climatic areas and placing categories for which
brushes are intended.
