This standard specifies a method for determining the apparent accuracy of petroleum waxes (hot-melt adhesives) containing additives. It is applicable to liquid hot melts, where the apparent viscosity is less than 20Pa.s at a temperature below 175 ° C. The standard requires the use of the International System of Units and prompts that hazardous materials, equipment and operations may be involved, and appropriate safety measures need to be established. In addition, the standard cites documents CB/T 265 and GB/T 514. Among them, CB/T 265 defines the dynamic viscosity determination method for petroleum products, while GB/T 514 specifies the technical conditions for liquid Glass thermometers. In terms of terms and definitions, the standard explains dynamic viscosity, that is, a measure of friction within a fluid indicating a liquid under a certain shear stress.
