FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the OccupationalSafety and Health and Chemical Hazards Sectional Committee had been approved by the Chemical Division Council.

High visibility warning clothe is one of the personnel protective equipment worn as a means to provide visual signalof the wearer 's presence and intended to provide conspicuity of the wearer under any light conditions by day andunder illumination by vehicle headlights in the dark . Conspicuity is enhanced by increasing the contrast betweenthe clothing and its ambient background or surroundings. Classes of visibility hazards are identified and appropriatemarkings for the clothing are suggested based on worker risk hazards , such as complex backgrounds, vehiculartraffic density and speeds.

Two different colours for background and combined performance materials are defined, providing opt ions forincreasing wearer's conspi cuity against most backgrounds found in urban and rural work environments. Usersshould consider the prevailing ambient background in which protection is required and select the colour providingthe preferred contrast.

Higher photometric performance levels of retroretlective material provide greater contrast and visibility over widerviewing angles of safety clothing when seen in headlights during darkness. When greater conspicuity is required,the higher performance level of retroreflective material should be used.

There is no ISO Standard on the subject. This standard is developed indigenously by taking considerable assistancefrom EN 471: 1994 'High Visibility warning clothing' .

The composition of the Committee responsible for the formulation of this standard is given at Annex D.

The standard is applicable to all kinds of organizations irrespective of its complexity as well as hazards associatedwith it and is voluntary in nature like all other management systems. A system ofthis kind enables an organizationto demonstrate its performance and conformity to the legal requirements. Certifying organization should provideinformation listing all the legislations as identified by the organization and covered in the certification process.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the result ofa test or analysis, shall be rounded off in accordance with IS 2 : 1960'Rulesfor rounding off numerical values (revised)' . The number of significant places retained in the rounded offvalue should be the same as that of the specified value in this standard.

ANNEXA(Clause 4 .2)

CONSPICUITY CLASSES AND EXAMPLES OFAPPLICABLE WORKERS

A-I It is recommended that the selecti on of conspicuity class be based on the class definition that best representsthe highest intermittent or continuous exposure encountered by the worker.

A-2CONSPICUITY CLASSES

Conspicuity Class 1

a) permit full and undivided attenti on to approaching traffic .

b) provide ample separation of the worker from conflict ingvehicle traffic.

c) permit optimum conspicuity in backgrounds that are notcomplex . and

d) involve vehicle and moving equipment speeds not exceed­ing40kmlh.

Conspicuity Class 2

Conspi cu ity level for use in occupational activit ies whererisk levels exceed those in Class I. such as where:

a) greater visibility is desired during inclement weatherconditions.

b) complex backgrounds are present.

c) workers are performing tasks which divert attention fromapproaching vehicle traffic.

d) vehicle of moving equipment speeds exceed 40 km/h , and

e) work activities take place in or in near proximity tovehicle traffic .

Conspicuity Class 3

Conspicuity level for use in occupational activities where risklevels exceed those in Class 2, such as where :

a) workers are exposed to traffic speeds exceeding 80 km/h,

b) pedestrian worker and vehicle operator have high taskloads. clearly placing the pedestrian worker in danger. and

c) the worker must be conspicuous through the full range ofbody motions at a minimum of 390 m ( I 280 feet). andmust be identifiable as a person.

C·2.4 Procedure

C·2.4.1 To the extent allowed by the availableinstrument select the appropriate source type,illuminating and viewing geometry and the wavelengthrange and wavelength measurement interval.

C·2.4.2 When the instrument is interfaced to acomputer so that calculation of CIE tristimulus valuesand derived color coordinates automatically followsmeasurement, select the variables defining thesecomputations .

Measurements shall be made on square samples of10 ern x 10 cm or of the size of the pre-tested samples.

Ra for the sample shall be measured at the specifiedobservation angle and entrance angle for both the 00,and 900 positions of the rotation angle E. The position00 is determined by one of the following means :

a) A clear datum mark on each sample, and

b) A clear instruction given by the manufacturerof the material.

If no mark or instruction exists. the position E = 00 canbe chosen at random.

C·4.6 Retroretlective Performance in Rainfall

Samples sha ll be tested in accordance with the methodspec ified under C-4.6.1 to C-4.6.3 .

C-4.6.1 Principle

A spec ime n of the material is mounted in a vertical planeand subjected to a continuous spray of wat er droplets,Measurements are made of the coefficient ofretroretlection of the wetted surface while the spray ismaintained , simulating the optical behavior of a surface

in a shower of rain.

C·4.6.2 Apparatus

A suita ble apparatus for mounting the speci men in the

FIG.5 A pPARATUS FOR THE W ET R ETROR EFLECTIO:'o: TEST

10

The specimen A is supported on the vertical specimenholder B above the catch trough C and drain D. Thespecimen holder is rigidly attached to the goniomet ertable (not shown) but is held away from it. The spraynozzle E is rigidly supported in a position which is fixedrelative to the specimen and is supplied with tap waterat constant but adjustable pressure through a tlexiblejoint F or hose.

The nozzle is one metre away from the specimen and isso angled that the spray strikes the spec imen at an angleof 10° to the vertical. The specimen, specimen holderand spray nozzle are enclosed in a cover G designed toprotect the optical apparatus from water.

Preferabl y, the cover is made of or incorporated largeareas of rigid transparent plastics material for visibil ityand has at least one removable panel or door for ac­cess. A square aperture H of side 150 mm is providedfor the light path and a gutter J protects this aperturefrom faiIing water. The region of the cover near to thisaperture is painted matt black to reduce spray reflec­tions. The nozzle consists of an orifice of diameter I.19mm with an appropriately designed feed pipe produc­ing a substantially uniform solid cone spray.

IS 15809 : 2008

C-4,6 .3 Procedure

Calibrate the apparatus for measuring the coefficient ofretroreflection R' with the wet testing apparatus in place.under both dry and wet cond itions and determine acorrection for change in spray light between these twoconditions.

Mount a flat, square specimen of the material of sidenot less than 50 mm in a vertical plane of the verticalspecimen holder so that the holder does not protrudebeyond the edge of the specimen at any point. If thematerial is orientation sensitive when dry, as describedin 6.1 mount it so that measurements can be made at theorientation which gate the lowest performance whendry.Adjust the nozzle and water supply to subject the speci­men to a spray of ordinary tap water such that the wholeface of the specimen is within the envelope of the spray,the angle 8 between the surface of the specimen and thewater striking it is not less that 50, and the flow ratestriking the specimen is equivalent to a rainfall, in mil­limeters per hour, of 50/ tan 8 as measured in a horizon­tal collector. Maintain the spray in a steady state for atleast 2 min before and throughout the measurement.
