基本信息

标准简介

This document specifies the principle, apparatus, materials, specimens, test procedure, calculation, test results and test report of the methods for determining the density and relative density of fiber reinforced plastics by the buoyancy method and the geometric method. This document is applicable to the determination of the density and relative density of fiber reinforced plastics. The buoyancy method is applicable to materials with low moisture absorption, and the geometric method to materials with high moisture absorption or porous materials. In the buoyancy method, water as the immersion liquid is applicable to specimens of fiber reinforced plastics with a density greater than 1 000 kg/m^{3} that are not affected by water; a non-aqueous solvent as the immersion liquid is applicable to specimens with a density less than 1 000 kg/m^{3} or strongly affected by water.
