This International 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, for example, clothing that is exposed to repeated splashes of liquid spray under pressure. Protective clothing "pass/fail" determinations are based on visual detection of liquid penetration. This test method is normally used to evaluate the barrier effectiveness against liquids of materials used for protective clothing and specimens from finished items of protective clothing. 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 method can be used to identify protective clothing materials and constructions that limit exposures to hazardous liquid chemicals under a variety of circumstances. This test method is particularly useful for demonstrating the liquid hold-out capabilities of microporous fabrics. Significant amounts of hazardous materials can permeate specimens that pass penetration tests. More sensitive analysis of permeation can be carried out using ISO 6529. Penetration resistance of protective clothing materials using less severe liquid challenges, without pressure, can be carried out using ISO 6530. ISO 6530 uses a relatively low-volume, short-duration liquid challenge which is appropriate for treated porous and other non-film-based or uncoated materials. This International Standard addresses only the performance of materials or certain material constructions (e.g. seams) used in protective clothing. It does not address the design, overall construction and components, or interfaces of garments or other factors which may affect the overall protection offered by the protective clothing. It is emphasized that the test method specified in this International Standard does not necessarily simulate conditions that clothing materials are likely to be exposed to in practice. Therefore the use of test data is to be restricted to broad comparative assessment of such materials according to their liquid penetration resistance characteristics.
