GB/T 13354-1992: Test method for density of adhesives in fluid form. Method of weight cup

This Standard specifies the method for measuring the density of liquid adhesives and their components by a 37.00mL weight cup. This Standard is applicable to the determination of the density of liquid adhesives; especially for liquid adhesives whose viscosity is higher or the components are more volatile, and it is not appropriate to use the pycnometer method to determine the density.

Method of Weight Cup
1 Subject Contents and Applicable Scope
This Standard specifies the method for measuring the density of liquid adhesives and their components by a 37.00mL weight cup.
This Standard is applicable to the determination of the density of liquid adhesives; especially for liquid adhesives whose viscosity is higher or the components are more volatile, and it is not appropriate to use the pycnometer method to determine the density.
2 Definition
Density: The mass per unit volume of the liquid adhesive at a specified temperature (weight in a vacuum). The density in this method is obtained through dividing the mass of the liquid adhesive in a weight cup with a capacity of 37.00 mL at 20??C by 37.00mL. 3 Apparatus
3.1 Weight cup: a metal cup with a capacity of 37.00 mL at 20??C.
NOTE: The domestically-produced weight cup that satisfies this Standard is called "QBB Specific Gravity Cup".
3.2 Constant temperature bath or constant temperature room: Can maintain at 23??1??C. 3.3 Balance: Sensitivity is 0.001g.
3.4 Thermometer: 0~50??C, with division of 1??C.
4 Test Procedures
4.1 Prepare an adhesive sample sufficient for three tests.
4.2 Wash the weight cup by a volatile solvent and dry it.
