1.1 This practice covers the determination of the stability in storage of liquid enzyme-based, terpene-based, and solvent-based chemical cleaning compounds used to clean the exterior surfaces of aircraft. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.1 These test methods cover sampling and analysis of high purity water from water purification systems and water trans-mission systems by the direct sampling tap and filtration of the sample collected in the bag. These test methods cover both the sampling of water lines and the subsequent microbiological analysis of the sample by the culture

1.1 This test method provides a procedure for determining the resistance ofresilient floor covering to surface deterioration when exposed to various chemical reagents. This test method is not intended as a staining test nor as a method to judge surface and appearance restoration of the sample after exposure to chemical reagent. 1.2 The values stated
