Protective gloves against thermal risks.
The standard specifies the requirements, the test methods, the information to be provided and the marking of protective gloves against heat or fire.
Definition and requirements: The nature and protection level are indicated by a pictogram followed by a series of six figures that specify the level of performance for the corresponding risk conditions.
