What is EN ISO 11612:2019?

EN ISO 11612:2019 is an international standard that specifies the performance requirements for protective clothing made to protect against heat and flame. It provides guidelines for assessing the level of protection offered by garments in various industrial environments where workers may be exposed to heat and flames. This standard plays a crucial role in ensuring the safety and well-being of employees working in high-risk industries such as oil and gas, chemical manufacturing, firefighting, and welding.

Key Requirements of EN ISO 11612:2019

The standard outlines several essential requirements that protective clothing must meet to provide effective heat and flame protection. These requirements include:

Flame resistance: The garment should resist ignition and continue to provide protection even after exposure to flames.

Heat resistance: The material used in the garment should have adequate thermal stability to protect against heat transfer.

Tensile strength and tear resistance: The clothing should have sufficient strength to withstand potential mechanical hazards.

Seam strength: All seams in the garments should maintain their integrity under thermal stress.

Dimensional change: The clothing should not shrink significantly when exposed to heat.

Molten metal splash resistance: The garment should shield against molten metal splashes.

Electrical properties: If applicable, the clothing should have antistatic properties to reduce the risk of electrical discharge.

Testing and Certification

For a garment to comply with EN ISO 11612:2019, it needs to undergo rigorous testing performed by certified laboratories. These tests evaluate the clothing's resistance to flame, heat, and other specific hazards. Only garments that pass these stringent tests receive certification and are labeled accordingly.

It is essential for organizations to ensure that the protective clothing used by their employees meets the requirements of EN ISO 11612:2019. Regular inspections, maintenance, and proper handling of the garments also play a vital role in ensuring their continuous effectiveness.


EN ISO 11612:2019 is a vital standard that sets the benchmark for protective clothing designed to safeguard workers against heat and flame-related risks. Adhering to this standard helps ensure the safety and well-being of individuals working in hazardous environments. By providing comprehensive guidelines and testing protocols, EN ISO 11612:2019 enables organizations to make informed choices when selecting protective clothing, ultimately reducing the potential for injuries and accidents.
