This standard specifies methods for testing the color of liquid chemical products (excluding petroleum products) at room temperature. Remarks 1.Chemical products refer to all substances produced by chemical reactions, but if the standards for an individual product or product group specify a measurement method different from this standard, the method specified in that standard shall be used. Depends on how you are. 2. Some chemical products are highly volatile, explosive, radioactive, etc., so testing safety cannot be ensured when using this standard. The methods stipulated in this standard are general methods and should be applied to cases where safety can be sufficiently ensured in advance.
