Значение и использование >The purpose of this test is not to fully identify and characterize a polymer, but to identify a variety of basic parameters needed to predetermine the usefulness of the polymer in formulations as well as for Quality Control purposes.

A statement of precision and accuracy is not appropriate in this case.

1.1 These test methods cover test procedures for emulsion polymers that are used in water-based floor polishes. The term “emulsion polymers” is used primarily to denote those materials produced by regular emulsion polymerization techniques, but may be extended to those polymers that are subsequently emulsified or dispersed after polymerization. Unless otherwise noted, the tests may be used for any polymer or copolymer systems. The methods appear in the following order:
