Protective clothing - Protection against heat and flame - Requirements and test methods for garments with integrated smart textiles and non textile elements

This document applies to garments and assembly of garments providing protection against heat and flame, with integrated smart textiles and non-textile elements for enhanced health, safety and survival capabilities.
This document does not concern validating claims that the integrated smart textile and non-textile elements substitute directly any protection provided by the garment from a heat and flame perspective.
The integrated smart textiles and non-textile elements could include not only the parts integrated into the protective garment but also connections to transmit the data generated or exchange data with external devices. It is not within the scope of this document to evaluate either the data storage or transmission (including connectivity) to the external devices, nor the external devices. This document evaluates only the smart textiles and non-textile elements integrated into the garment.
This document supplements the requirements of EN ISO 11612 and EN ISO 13688 and does not replace any of the requirements cited in those documents.
This document sets additional testing and performance requirements linked specifically to the garments and assembly of garments providing protection against heat and flame, with integrated smart textiles and non-textile elements for enhanced health, safety and survival capabilities. These additional requirements will depend on the functionality of the smart textile or non-textile element and its needed efficacy during heat and flame hazards and risks from an electrical/electronic safety perspective in these situations.

Introduction

This document concerns garments or assembly of garments providing protection against heat and

flame, with integrated smart textiles and non-textile elements for enhanced health, safety and survival

capabilities.

This document does not concern validating claims that the integrated smart textile and non-textile

elements substitute directly any protection provided by the garment from a heat and flame perspective.

The integrated smart textiles and non-textile elements may include not only the parts integrated into

the protective garment but also connections to external devices and the data generated and exchanged.

It is not within the scope of this document to evaluate data storage or transmission as well as the

connectivity to the external devices other than the hardware integrated into the garment.

The garments or assembly of garments as a whole will need to fulfil the heat and flame requirements of

EN ISO 11612 and the general clothing requirements EN ISO 13688. The smart elements shall be

treated similarly to hardware when testing according to these two standards.

The purpose of this document is to provide the additional requirements on identifying the need for

additional testing of the smart textiles or non-textile elements and how they should be tested from a

heat and flame perspective. Additional requirements, if applicable, from an electrical/electronic safety

perspective also are addressed. The applicability of the additional requirements will need to be

evaluated depending on the functionality of the smart textile or non-textile element and its needed

efficacy in a heat and flame risks. At a minimum the smart textile or non-textile elements should not

negatively impact the protection that the garment intends to fulfil.

This document is complementary to and does not intend to repeat the requirements of EN ISO 11612

and/or EN ISO 13688.

It is essential that the industrial workers using heat and flame personal protective equipment (PPE) and

fire (and rescue) services, or their employers, carry out a risk assessment as well as a compatibility and

ergonomics check of all parts of the PPE (e.g. SCBA, gloves, boots, etc.) to meet the requirements of the

Directive (EC) 89/656 on the minimum health and safety requirements for the use by workers of

personal protective equipment at the workplace. It is essential that workers and maintenance

personnel are trained in the selection, use, care and maintenance of all personal protective equipment

including the smart elements. Guidelines for selection, use, care and maintenance of garments or

assembly of garments with integrated smart textiles and non-textile elements for enhanced health,

safety and survival capabilities (smart garments) protecting against heat and flame are given in

CEN/TR 17620.

This document was prepared under the standardization request M/553 as regards advanced garments

and ensembles of garments that provide protection against heat and flame, with integrated smart

textiles and non-textile elements for enhanced health, safety and survival capabilities, in support of

Regulations (EU) No 1007/2011 and (EU) 2016/425 of the European Parliament and of the Council.

This document fulfils the request for (a) European standard(s) in the field of declaration and

measurement of properties and overall performance of advanced garments and ensembles of garments

that provide protection against heat and flame, with integrated smart textiles and non-textile elements

for enhanced health, safety and survival capabilities as stated in Annex II of the standardization request.

As this request left it open to choose the detailed the committee decided to focus (i) on EN ISO 13688 as

this document is an integral part of all PPE product standards for heat and flame protection and (ii) to

not limit the application to only one or two categories of PPE (thus to include CAT III), which is why

EN ISO 11612 rather than ISO 14116 was chosen.

1 Scope

This document applies to garments and assembly of garments providing protection against heat and

flame, with integrated smart textiles and non-textile elements for enhanced health, safety and survival

capabilities.

This document does not concern validating claims that the integrated smart textile and non-textile

elements substitute directly any protection provided by the garment from a heat and flame perspective.

The integrated smart textiles and non-textile elements could include not only the parts integrated into

the protective garment but also connections to transmit the data generated or exchange data with

external devices. It is not within the scope of this document to evaluate either the data storage or

transmission (including connectivity) to the external devices, nor the external devices. This document

evaluates only the smart textiles and non-textile elements integrated into the garment.

This document supplements the requirements of EN ISO 11612 and EN ISO 13688 and does not replace

any of the requirements cited in those documents.

This document sets additional testing and performance requirements linked specifically to the

garments and assembly of garments providing protection against heat and flame, with integrated smart

textiles and non-textile elements for enhanced health, safety and survival capabilities. These additional

requirements will depend on the functionality of the smart textile or non-textile element and its needed

efficacy during heat and flame hazards and risks from an electrical/electronic safety perspective in

these situations.

flame exposure. Exposure to gaseous products should be prevented by adequate ventilation of the

chamber. Appropriate care shall be taken prior and during testing for materials or components/devices

(e.g. batteries) that that may combust or potentially explode upon exposure to the temperatures applied

during testing.

Garments and assembly of garments providing protection against heat and flame, with integrated smart

textiles and non-textile elements shall meet the requirements of EN ISO 11612 and EN ISO 13688,

unless specific provisions of these standards are modified in this document. In any case, the integrated

smart textiles or non-textile elements shall not negatively impact these requirements.

This document is split in three main requirements sections, adding to or modifying the interpretation

of:
• EN ISO 13688;
• EN ISO 11612;

• Safety of the smart textile or non-textile elements (with a focus on electric components).

NOTE Since the requirements of EN ISO 13688 are included in the requirements of EN ISO 11612, any
