Specifies the requirements for protective clothing intended to provide limited protection against penetration by specific liquid chemicals where liquid chemicals in droplet form are to be protected against or where more substantial splashes of a chemical are sustained the clothing is able to be removed immediately.

This Standard specifies requirements for clothing providing limited protection against specific liquid chemicals which may impinge on the wearer by processes of splashing, dripping or low pressure spraying.This Standard provides minimum safety requirements for clothing which provides protection against-(a) occasional exposure to droplets or small drips of specific liquid chemicals; or (b) a brief exposure to a low pressure jet or splash of specific liquid chemicals, whereby protection is provided for sufficient time to remove contaminated clothing before penetration of the chemical through the clothing occurs.This Standard does not apply to clothing for protection against escaping liquids from pressurized systems, large spillage or overflows. It also does not apply to clothing designed to be resistant to volatile liquids with a high order of toxicity or other highly toxic or corrosive liquids. Requirements for clothing to protect against these hazards are given in Part 1 of this Standard (see Clause 1.2).
