(Test Method)Standard Test Methods for Corrosivity of Solvent Systems for Removing Water-Formed Deposits
Standard Test Methods for Corrosivity of Solvent Systems for Removing Water-Formed Deposits
SCOPE
1.1 These test methods cover the determination of corrosivity of solvent systems used to remove water-formed deposits from the metal and alloy surfaces of water handling equipment. Four test methods are given as follows: Sections Test Method A-Corrosivity in the Absence of Deposits 10 to 15 Test Method B-Corrosivity in the Presence of Selected Ions 16 to 21 Test Method C-Corrosivity with Magnetite-Coated Steel Specimens 22 to 28 Test Method D-Corrosivity with Deposit-Coated Specimens 29 to 35
1.2 Test Methods A and B provide for corrosivity testing under either static immersion or dynamic conditions.
1.3 Test Methods C and D are procedures applicable for corrosivity testing under static immersion conditions only.
1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
