Oil Resistance	53-55
Preparation of Test Specimens	7
Specific Gravity	9-12
Temperature Index	48-49
Time of Drying	32-36
Varnish Compatibility	50-52
Viscosity	13-16

1.2 Where the entire test method is included in this standard, the precision and bias are not known unless given in the stated method.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 5.
