(Equivalent Test Methods: IP 160, ISO 3675, DIN 51757H, JIS K 2249H, and AFNOR T60-101)
EXPLANATION
See under Gravity, API Test Method D287.
TEST SUMMARY
The sample is brought to the prescribed temperature and transferred to a cylinder at approximately the same temperature. The appropriate hydrometer is lowered into the sample and allowed to settle. After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the sample is noted. If necessary the cylinder and its contents may be placed in a constant temperature bath to avoid excessive temperature variation during the test.
