DENSITY - GB/T4085-2005

1. TOOLS
1.1 Balance accurate to 0.0001 g
1.2 Container
1.3 Metal wire, diameter≤0.5 mm

2. SAMPLING
3*10x10 mm
Distilled water at 23(+/-0.5) ℃

3. ENVIRONMENTAL CONDITIONS
Perform the test under the environmental conditions described in GB/T 2918-1998

4. TESTING PROCEDURE
4.1 Weigh (m1) the sample to an accuracy of 0.0001 g

4.2 Locate the container with distilled water on the scale, and zero the latter

4.3 Suspend the sample into the water with the help of a thin wire

4.4 Weigh(m2) the container with the sample suspended in distilled water to an accuracy of 0.0001g

4.5 Record the results ρs=(m1/m2)×ρw
ρw: density of distilled water at 23(+/-0.5) ℃

5. ASSESSING TEST RESULTS
Passing requirement: +/-50 kg/m3 of the agreed nominal density
