Protective clothing against liquid chemicals. 
Performance requirements for clothing with liquid-tight (Type 3) or spray-tight (Type 4) connections, including items providing protection to parts of the body only (Types PB [3] and PB [4])
 

This document specifies the minimum requirements for the following types of limited use and reusable chemical protective clothing:

Full-body protective clothing with liquid-tight connections between different parts of the clothing (Type 3: liquid-tight clothing) and, if applicable, with liquid-tight connections to component parts, such as hoods, gloves, boots, visors or respiratory protective equipment, which may be specified in other European Standards.
Examples of such clothing are one-piece coveralls or two-piece suits, with or without hood or visors, with or without boot-socks or over-boots, with or without gloves;

Full-body protective clothing with spray-tight connections between different parts of the clothing (Type 4: spray-tight clothing) and, if applicable, spray-tight connections to component parts, such as hoods, gloves, boots, visors or respiratory protective equipment, which may be specified in other European Standards.
Examples of such clothing are one-piece coveralls or two-piece suits, with or without hood or visors, with or without boot-socks or over-boots, with or without gloves;

Partial body protection garments offering protection to specific parts of the body against permeation of chemical liquids.
Examples of such garments are e. g. laboratory coats, jackets, trousers, aprons, sleeves, hoods (not air- supplied) etc.
As partial body protection leaves some parts of the body unprotected this document specifies only the performance requirements for the clothing material and the seams.

NOTE  Partial body chemical protective garments which offer only protection against penetration of chemical liquids are within the scope of EN 13034 (Type PB [6] clothing).
