4、ation F438.1.2 The products covered by this specification are intended for use with the distribution of pressurized liquids only, which arechemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems withcompressed air or other compressed ga
5、ses, some manufacturers do not allow pneumatic testing of their products. Consult withspecific product/component manufacturers for their specific testing procedures prior to pneumatic testing.NOTE 2Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which pr
