IS 8347 : 2024 Respiratory Protective Devices - Definitions, Classification and Nomenclature of Components
| ICS 01.040.13; 13.340.30 | CHD 08 |
1 SCOPE
This standard cover nomenclature of components in respiratory devices. It specifies a classification of the environment where the use of respiratory protective devices [RPD] may be necessary and a classification of respiratory protective devices according to their design. The standard defines the commonly used terms and pictograms of this area. The natural composition of air and the requirements for the purity of breathable air are given in Annex A.
