National foreword

This British Standard has been prepared by Technical Committee PH/3 and is

the English language version of EN 863:1995 Protective clothing — Mechanical

properties — Test method: puncture resistance, published by the European

Committee for Standardization (CEN)

A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application

Compliance with a British Standard does not of itself confer immunity from legal obligations.

Foreword

This European Standard was prepared by

CEN/TC 162, Protective clothing including hand

and arm protection and lifejackets, the secretariat of

which is held by DIN

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 of

the EU Directive 89/686/EEC

For relationship with EU Directives,

see informative Annex ZA, which is an integral

part of this standard

This European Standard shall be given the status of

a national standard, either by publication of an

identical text or by endorsement, at the latest by

March 1996, and conflicting national standards

shall be withdrawn at the latest by March 1996

According to the CEN/CENELEC Internal

Regulations, the following countries are bound to

implement this European Standard: Austria,

Belgium, Denmark, Finland, France, Germany,

Greece, Iceland, Ireland, Italy, Luxembourg,

Netherlands, Norway, Portugal, Spain, Sweden,

Switzerland, United Kingdom

1 Scope

This European Standard specifies a test method for

measuring the puncture resistance of protective

clothing or materials used for these products

The puncture resistance is expressed as the

maximum force required to push a spike with a

specified speed through the test specimens

2 Normative references

This European Standard incorporates by dated or

undated reference, provisions from other

publications These normative references are cited

at the appropriate places in the text and the

publications are listed hereafter For dated

references, subsequent amendments to or revisions

of any of these publications apply to this European

Standard only when incorporated in it by

amendment or revision For undated references the

latest edition of the publication referred to applies

EN 10002-2, Metallic materials — Tensile testing —

Part 2: Verification of the force measuring system of

the tensile testing machines

ISO 2231:1989, Rubber- or plastics-coated fabrics —

Standard atmospheres for conditioning and testing

3 Test specimens

Take four representative test specimens from the

sample, each 50 mm minimum diameter, so that the

specimens fit between the bolt holes of the clamps

4 Test method

4.1 Apparatus

4.1.1 Tensile testing machine

In this method a tensile testing machine type CRE

as defined in EN 10002-2 is used and shall be

capable of:

— a vertical travel of at least 100 mm;

— a constant rate of compression

of (100 ± 10) mm/min;

— a recording apparatus for the force and

deformation

4.1.2 Test spike

The test spike shall be made of steel, with a

minimum hardness of 60 HRC and shall have the

dimensions and the characteristics as shown in

Figure 1

The test spike shall be checked by an optical enlargement after every 500 tests or at least once a year When testing materials which wear out the test spike, the optical checks should be done more frequently If this test shows that the test spike dimensions do not comply with the dimensions of Figure 1, the test spike shall be discarded

NOTE The control of the dimensions of the test spike is important It is recommended that every test laboratory maintains an internal reference material to do regular checks on the results of the testing.

4.1.3 Clamps

The clamping rings have to prevent slippage during the test They consist of two 10 mm minimum thick steel plates, each having a (20 ± 0,5) mm diameter hole in the centre and four clamping bolts, as shown

in Figure 2

NOTE Gripping aids can be used if necessary to prevent slippage or reduce damaging of the specimen.

4.2 Conditioning

The specimens shall be conditioned and the test shall be conducted in the standard atmosphere as described in ISO 2231, i.e at a relative humidity

of (65 ± 5) % and a temperature of (20 ± 2) °C

Conditioning at a specified relative humidity may be omitted if it can be shown that the results for the type of material under test were not affected

4.3 Procedure

Secure the specimen between the clamping rings with the outer surface exposed to the test spike, tighten the nuts sufficiently to ensure no slippage

of, or damage to, the specimen Place the specimen and the clamping rings in the tensile testing machine Advance the spike on to and through the specimen at a rate of (100 ± 10) mm/min If the spike fails to penetrate after a movement of 25 mm after contact with the specimens, the test is

terminated This shall be referred to in the test report

Repeat the procedure on the remaining specimens Record for each test the maximum force

(in newtons) needed to penetrate the specimen

5 Calculation of results

Calculate the arithmetical mean of the maximum force (in newtons) needed to puncture the four test specimens, rounded to the nearest value

EN 863:1995

6 Test report

The test report shall include the following

information:

— the number and the date of this European

Standard;

— all details necessary for the identification of

the sample tested;

— the results obtained for each test specimen;

— the mean value in newtons;

— any deviation from the procedure outlined in this standard

Annex ZA (informative)

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

Directive 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 clauses of this standard are likely to support requirements of 3.3 of Annex II “Protection against

physical injury” of EU Directive 89/686/EEC

Compliance with these clauses of this standard provides one means of conforming with the specific

essential requirements of the Directive concerned and associated with EFTA requirements
