The standard defines the scope of the normative document and specifies the technical requirements, acceptance rules, test methods, safety requirements, storage and transportation conditions, and manufacturer's warranties for the product called "laundry soap". The composition of the finished detergent depends on the formulation, which is characterized by the content of fatty acids. Production is divided into three groups. Soap in each group is available with its assortment name.

The requirements of the standard must be strictly observed in the manufacture, use and implementation.

In the form of solid rectangular bars let out a soap economic. The composition of the finished product for the content of fatty acids varies from 64 to 72%:
