Processes are identified in which changes may occur in the composition of chemical substances due to oxidation-reduction reaction, etc. or in the concentration of chemical substances due to evaporation, sublimation, etc. and appropriate management measures are implemented.
Note 1: Examples of applicable processes: plating, coating, printing, molding, flow soldering, two-liquid mixture adhesive bonding, etc.
Note 2: If an organization manufacturing articles from substances/preparations is unable to understand the change in chemical composition, verification is implemented by asking the supplier.
