1.1 This test method measures the ability of protective clothing or protective ensembles to resist liquid penetration in the form of a shower spray with surfactant-treated water.
1.2 This test method measures the liquid penetration resistance of the construction and configuration of the overall protective clothing or protective ensemble, but especially of seams, closures, and interfaces with other components such as gloves, boots, hoods, and respiratory protective equipment. It is intended that this test method be used to assess the liquid penetration resistance of protective clothing and protective ensembles as received from the manufacturer and worn in accordance with their instructions.
1.3 Resistance of materials used in protective clothing to permeation or penetration can be determined in accordance with Test Methods F 739 and F 903, respectively.
1.4 The integrity of vapor protective ensembles is measured by its ability to maintain positive internal pressure with Test Method F 1052.
1.5 The values in SI units or in other units shall be regarded separately as standard. The values stated in each system must be used independently of the other, without combining values in any way.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
