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. Astn sources generated by this practice are equal to the uncertainty Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Typically, exposures conducted according to this practice will produce degradation faster than similar exposures conducted according to Practice D or D and may cause different types of degradation.

For more specific safety precautionary information see 1. Refer to Test Method E Preparations of Aqueous Solutions 7. 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. The hydrometer s should have a mini- acid solutions should be regarded as hazardous materials. Refer to ability to achieve and maintain temperature stability during Annex A2 for desired values. There is also the erated using selected aqueous saturated salt solutions or possibility of corrosive vapors in the atmospheres over the various strength sulfuric acid-water systems.

The reference document by Greenspan9 contains information 8. The vent should be as small as practical to Saturated Salt and Glycerol Solutions. This standard has been approved for use by agencies of the Department of Defense. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
