FOREWORD

This Malaysian Standard was prepared by the Working Group on Protective, Helmets for

Motorcyclists

under the authority of the Mechanical Engineering

Industry

Standards Committee.

This standard supersedes MS 1969, ‘Protective

helmets

for motorcyclists’. However, for

implementation purposes, both the old and the new standards shall operate

concurrently

until

December 31,

1990. MS

1

1969

will

be

withdrawn from

use

after

that

date.

The

scope

of the revised standard is wider in that it covers al l

types

of helmets, both for

racing

and

for ordinary use. The methods of test for impact

resistance,

penetration

and

strength of

retention

system have

been

changed

in

line

with current

international praátice.

In the preparation of this standard, references were

made

to the following standards:

a ANSI Z90, 1-197

Protective

headgears for vehicular users

b AS 1698—1980

Protective

helmets

for vehicular users

c ECE

R-22 Uniform

provision concerning the approval of protective helmets for drivers

The

helmet, shall be

positioned

as specified

in

clause

11, and subjected

to

impact at

four

sites

with

two

successive impacts

at

each

site.

The centres

of

each pair

of

impacts

shall be

not more

than 6 mm

apart.

All impact sites shall be above

the

reference line and

shall be

separated

from each other by a distance not

less than one-sixth of the

maximum

circumference of

the

helmet. Two pairs of impacts shall be upon

a

flat steel anvil and two upon

a hemispherical steel anvil.

12.1.3

Calibration

of

test

apparatus. The test

apparatus

shall be calibrated

before

and after

each series

of

tests

in respect of the

velocities

of

impact,

which

shall not

differ by

more than 3

per

cent

from

the

velocities impact

theoretically obtained

from

free fall

in vacuo at the test

location from the specified drop heights of

1 8 3 0

mm and 2150 mm.

12.2

Penetration

test

12.2.1 Method. The penetration test shall

be

conducted

by

dropping the penetration

test

striker in

guided free fall, with

its axis

aligned vertically, onto the outer surface of a rigidly

mounted helmet,

positioned

on

a hemispherical

test block of

hardwood

with a

soft

metal

insert

at

the top of its central axis. This shall be mounted on

a

rigid base see fig. 6 .

The

mass

of the

penetration test

striker

shall be 4.5

±0.045 kg.

The

point

of the striker

shall have an

included

angle

of 6 0

±

0.5 degrees

and

a

cone

height of

not

less than 3 8 mm. The

striking point

shall have a

radius

of

0.5

±

0.1

mm and a

hardness

of at least

60

Rockwell

scale C .

At

least

the tip

of

the striker shall

be

electrically conductive.

The

rigid

mount for the penetration test

block

shall

be as

specified for the

anvil

base

12.1.1 .

The

height

of

the

guided free fall shall be 2000 ±

15

mm as measured from

the

striker point to

the

impact

point

on

the outer

surface

of the helmet.

12.2.2 Procedure. The helmet, with the adjusting components above the basic plane fully

relaxed shall be

positioned

on

a

rigidly mounted wooden test block and subjected to at least two

penetration

blows at sites above

the

reference line,

determined

by

using the

headform described

in clause 10.

These sites shall be at least 7 6 mm

apart,

and at least 7 6 mm from

the

centres of

any

impacts

applied during

the

impact energy attenuation test.

NOTE. Whether or

not

electrical contact

shall be

conducted

by

applying a

static

tensile load through a

loading

device

to

the retention

system

of a

helmet

when positioned

as
