ASTM D1176-98(2002)

Standard Practice for Sampling and Preparing Aqueous Solutions of Engine Coolants or Antirusts for Testing Purposes

SIGNIFICANCE AND USE
This practice is used commonly by vehicle service or laboratory personnel for sampling and preparing aqueous solutions of engine coolants or antirust for further evaluation and testing.
This practice shall be followed when sampling and preparing aqueous solutions of products for evaluation in ASTM test methods.
Care must be taken to ensure that a representative sample of product is taken.
This practice describes several different test methods. The methods to be followed should be agreed to by the supplier and the customer.
SCOPE
1.1 This practice covers information on sampling and preparing solutions of engine coolants and antirusts (Note 1 Note 2).
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are approximate equivalents given for information only.
1.23 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.
Note 1—Antirust as referred to in this practice covers products intended for use in automotive/light-duty and heavy-duty applications in which water is used as the cooling medium.
Note 2—Antirust products are available in liquid and solid form. Solids should be handled as outlined in .
