Clothing for protection against liquid chemicals - Determination of the resistance of protective clothing materials to penetration by liquids under pressure
 N JIS T 8031

Annotation

This Standard describes a laboratory test method that enables determination of the resistance of materials used in protective clothing to visible penetration under the conditions of continuous liquid contact and pressure based on visual detection of liquid penetration.

This test method IS used to evaluate the barrier effectiveness against liquids of materials used for protective clothing and specimens from finished items of protective clothing. An example of relevant clothing is the clothing that is exposed to repeated splashes of liquid spray under pressure.

NOTE 1 Finished items of protective clothing include not only the whole-body chemical protective clothing but also gloves, arm shields, aprons, suits, hoods, footwear and the like. Furthermore, the phrase "specimens from finished items" encompasses seamed and other discontinuous regions as well as the usual continuous regions of protective clothing items.

This test is used to identify protective clothing materials and certain material constructions (e.g. seams) that limit exposures to liquid chemicals. It does not address the design, construction and components, or interfaces of garments or other factors that may affect the overall protection offered by the protective clothing. Furthermore, this test does not necessarily simulate all the conditions in which clothing materials are likely to be exposed to liquid chemicals in practice. Therefore the use of test data should be restricted to broad comparative assessment of such materials according to their liquid penetration resistance characteristics.
