Full title and description

St ISO 9151-2016 (2017) — Protective clothing against heat and flame — Determination of heat transmission on exposure to flame. This document is the international standard ISO 9151:2016 (edition 2), with corrected language published in March 2017; it specifies a laboratory test method to determine the heat transmission through materials and material assemblies used in protective clothing and to rank materials by heat transfer indices.

Abstract

ISO 9151:2016 specifies a method for determining the heat transmission through materials or material assemblies used in protective clothing when exposed to a defined flame source. The method yields heat transfer indices that allow comparative ranking of materials; the index is not intended as a direct measure of protection time under real-use conditions. The standard includes conditions for test specimen preparation, exposure and measurement and is intended for use in material evaluation and comparison.

Scope

Applies to materials and material assemblies intended for use in protective clothing against heat and flame and specifies a laboratory procedure for measuring heat transmitted through a specimen during exposure to a defined flame. Results are expressed as heat transfer indices for comparative ranking of materials; the standard does not claim to predict wearer survival time or full garment performance in field conditions.

Key topics and requirements

• Standardized flame exposure procedure to measure heat transmission through materials and assemblies.
• Calculation and reporting of heat transfer indices to permit material ranking and comparison.
• Requirements for specimen preparation, conditioning and dimensions to ensure repeatability.
• Measurement and instrumentation guidance for recording heat flux/temperature during exposure.
• Clear statement that heat transfer indices are comparative and not a direct measure of actual protection time in use.

Typical use and users

Used by test laboratories, PPE and textile manufacturers, material developers, certification and conformity assessment bodies, and occupational safety professionals who evaluate and compare materials for thermal and flame protective performance. Also referenced by specifiers and procurement teams when selecting materials for garments intended to limit heat transfer to the wearer.

Related standards

ISO 9151 is part of the family of standards on protective clothing and thermal protection developed under ISO/TC 94/SC 13. It is commonly used alongside ISO 11612 (Clothing to protect against heat and flame — minimum performance requirements) and other test-method standards that address specific heat hazards and garment-level performance.

FAQ

Q: What is this standard?

A: ISO 9151:2016 (published Nov 2016, corrected Mar 2017) is an international test-method standard that defines a laboratory procedure to measure heat transmission through materials or material assemblies when exposed to flame, producing heat transfer indices for material comparison.

Q: What does it cover?

A: It covers specimen preparation and conditioning, defined flame exposure conditions, measurement of transmitted heat and calculation/reporting of heat transfer indices. It is intended for material evaluation and comparison, not as a direct prediction of wearer survival time in real incidents.

Q: Who typically uses it?

A: Laboratory technicians, PPE and fabric manufacturers, conformity assessment/certification bodies, safety engineers, and procurement/specification professionals involved with thermal- and flame-protective clothing.

Q: Is it current or superseded?

A: ISO 9151:2016 is the current published edition (edition 2, published November 2016) with a corrected version issued March 2017; ISO records list the 2016 edition as published/confirmed. Users should check the issuing body for any later amendments or revisions before relying on the standard for compliance.

Q: Is it part of a series?

A: It belongs to the body of ISO standards addressing protective clothing and thermal hazards (work under ISO/TC 94/SC 13). It is often used in conjunction with standards such as ISO 11612 (clothing performance requirements for protection against heat and flame) and other related test-method and performance standards.

Q: What are the key keywords?

A: Protective clothing; heat transmission; flame exposure; heat transfer index; PPE testing; thermal protection; ISO 9151.
