Intro duct ion

This standard is intended as a supplement to the specific product standards for protective helmets (helmet standards) This method or other test methods may be applicable to specifications for complete helmets or parts thereof, and may be referenced in the appropriate helmet standards

Performance requirements are given in the appropriate helmet standard, as are such prerequisites as the number of samples, pre-conditioning, preparation of samples for the tests, sequence and duration oftesting and assessment of test results If deviations from the test method given in this standard are necessary, these deviations will be specified in the appropriate helmet standard

1 Scope

This European Standard describes methods of test for protective helmets The purpose of these tests is to enable assessment of the performance of the helmet as specified in the appropriate helmet standard This European Standard specifies conditions and conditioning to be used when testing protective helmets

2 Terms and definitions

For the purposes ofthis European Standard, terms and definitions used in this standard may be found in the appropriate helmet standard

3 Prerequisites

In order to implement this European Standard, at least the following parameters shall be specified in the appropriate helmet standard:

a) number of samples;

b) preparation of samples;

c) sequence of conditioning;

d) sequence of tests;

e) temperatures to be used

4 Test methods

4.1 General

Several methods are specified The appropriate helmet standard will state which of these method(s) idare applicable

4.2 Testing atmosphere

Testing in accordance with all parts ofEN 13087 shall be performed in an atmosphere with a temperature

of (22 * 5 ) "C and a relative humidity of (55 * 30) YO This atmosphere may be referred to as laboratory ambient conditions

4.3 Conditioning cabinet

The temperature and artificial ageing conditioning cabinets shall be sufficiently large to ensure that the helmets do not touch one another or the sides of the cabinet They shall be fitted with a fan to ensure effective air circulation

4.4 High t e m p e r a t u r e conditioning

Samples shall be maintained at one of the following temperatures, as specified in the appropriate helmet standard, for a period of time between 4 h and 24 h:

(+50 or +40) "C with a tolerance of *2 "C in each case

4.5 Low temperature conditioning

Samples shall be maintained at one of the following temperatures, as specified in the appropriate helmet standard, for a period of time between 4 h and 24 h:

(O, -10, -20, -30,-40) O C , with a tolerance of %2 "C in each case

Trang 7

``,`-`-`,,`,,`,`,,` -EN 13087-1 12000

4.6 Water conditioning Samples shall be water conditioned by one ofthe following methods, as specified in the appropriate helmet standard Tap water at a temperature not greater than 27 "C shall be used for both methods

Method 1 The sample shall be totally immersed in water for a period of time between 4 h and 24 h

Method 2 The sample shall be sprayed over its outer surface at a rate ofnominally 1 l/min for a period of time between 4 h and 24 h

4.7 Artificial ageing 4.7.1 P r i n c i p l e

The sample helmet is exposed to a specified irradiation from a xenon arc lamp

4.7.2 A y y u r u t u s

A fused silica envelope, high pressure xenon lamp of450 watt nominal power, operated in accordance with the lamp manufacturer's instructions

A means to ensure that the air temperature, measured at the sample position, does not exceed 50 "C

A means to support the helmets so that they are exposed to the radiation

4.7.3 P r o c e d u r e

Secure the helmet so that the plane tangential to the crown of the helmet is perpendicular to the direction

of radiation from the lamp and the distance between the crown of the helmet and the arc of the lamp

is (150 * 5) mm

Expose the sample to the radiation for (400 * 4) h Remove the sample and allow it to return to laboratory ambient conditions (4.2)

Annex A (informative)

Artificial ageing -Procedure

The helmet submitted to artificial ageing should be exposed to the radiation of a xenon arc lamp The

radiant energy of the lamp should be filtered to provide a spectral power distribution that closely

approximates that of terrestrial daylight

The helmet should be fixed on a cylindrical holder concentric to the lamp and which rotates at a speed

of 1 to 5 r/min around its axis

Each helmet which will subsequently be tested for shock absorption or for penetration should be orientated

so that the area oftest should be directed towards the lamp The plane tangential to the shell at this point

should be normal to a radius of the cylindrical holder

The radiant energy incident in the plane of the test areas should be either measured or calculated from

information provided by the manufacturer of the test apparatus The exposure interval should be adjusted

so that the exposed samples receive a total energy of 1 GJ/m2 over the wavelength range 280 to 800 nm

The samples should be sprayed with distilled or demineralized water (having a conductivity

below 5 mS/cm) intermittently with a cycle of 18 min of spraying and 102 min without spraying During

the latter periods the measured relative humidity should be (50 * 5 ) YO

The temperature within the test chamber should be measured with a black standard thermometer placed

at the same distance from the lamp as the exposed test areas of the helmets The temperature should be

maintained at (70 * 3) "C

Ail other test and calibration conditions for the apparatus should be in accordance with I S 0 4892-1

and with I S 0 4892-2, Method A

of diameter sufficient to accommodate complete helmets

NOTE 3

acceptable intensities in the sample surface plane required by this procedure

Not all available test apparatus, otherwise meeting the requirements of IS0 4892, will incorporate sample holder frames

The position of the water sprays may require adjustment in order to avoid interference with the test samples

The energy output ofthe xenon arcs should be capable ofbeing reduced below normal operational levels, so as to maintain

Annex ZA (informative)

Clauses of this European Standard addressing essential requirements or other provisions of EU Directives

Clause of this s t a n d a r d

This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association and supports essential requirements ofEU Directive on personal protective equipment (PPE) 89/686/EEC

WARNING Other requirements and other EU Directives may be applicable to the product(s) falling within the scope of this standard

The following clauses of this standard are likely to support requirements of Directive 89/686/EEC:

2.4 Personal protective equipment subject to ageing 2.12 PPE bearing one or more identification marks directly or indirectly related to health

4.7, Annex A 4.6

11.3 Comfort and efficiency 14.4, 4.5

Compliance with the clauses of this standard provides one means ofconforming with the specific essential requirements of the Directive concerned and associated EFTA regulations
