scope:
This Standard specifies the procedure for sampling and mass concentration measurement of airborne dust particles in the breathing zone of a person who performs welding and allied processes (the operator) and in the working environment.
NOTE 1 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
ISO 10882-1 : 2011 Health and safety in welding and allied processes - Sampling of airborne particles and gases in the operator's breathing zone - Part 1 : Sampling of airborne particles (MOD)
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
NOTE 2 Typical allied processes include thermal cutting, grinding, chipping or other works related to welding.
