National foreword

This British Standard is the UK implementation of EN 1149‑5:2018. It supersedes BS EN 1149‑5:2008, which is withdrawn.

The UK participation in its preparation was entrusted to Technical Committee PH/3/1, General Personal Protective Equipment.

A list of organizations represented on this committee can be obtained on request to its secretary.

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

Compliance with a British Standard cannot confer immunity from legal obligations.

This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 September 2018.

This European Standard was approved by CEN on 30 April 2018.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.

Introduction

This European Standard is part of a series of standards for test methods and requirements for electrostatic properties of protective clothing. Different parts are necessary, because of the various fields of application and materials.

EN 1149 consists of the following parts, under the general title “Protective clothing – Electrostatic properties”:

Part 1: Test method for measurement of surface resistivity
Part 2: Test method for measurement of the electrical resistance through a material (vertical resistance);
Part 3: Test methods for measurement of charge decay;
Part 4: Garment test (under development);
Part 5: Material performance and design requirements.

A complete garment test is under study. As long as such a test is not available, it may not be possible to perform full assessment of the electrostatic properties of protective clothing. This set of standards reflects the current state of knowledge.

Further guidance on the EN 1149 series and on the selection, use, care and maintenance of electrostatic dissipative protective clothing is given in CEN/CLC/TR 16832:2015 [1]1).

1 Scope

This European Standard specifies material and design requirements for electrostatic dissipative protective clothing, including hoods and caps, used as part of a total earthed system, to avoid incendiary discharges, where the minimum ignition energy of an explosive atmosphere is not less than 0,016 mJ.

In the context of this European Standard, a total earthed system is one in which personnel and other conductors are connected to earth via a resistance of less than 10⁸ Ω.

The material and design requirements do not presume adequate earthing of additional equipment worn or carried in contact with clothing, e.g. breathing apparatus, etc. If such additional equipment is required to be earthed, other requirements beyond the scope of this European Standard may be necessary.

The scope of this standard does not include electrostatic dissipative protective gloves or footwear that are separate and not integral parts of garments.

The material and design requirements may not provide sufficient protection in oxygen enriched flammable atmospheres.

NOTE Additional information about oxygen enriched flammable atmospheres can be found in CEN/CLC/TR 16832:2015 [1].

This European Standard is not applicable for protection against mains voltages.
