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:

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 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.

Significance and Use

Test Method A is necessary because the corrosivity of a solvent system can be detrimental to the equipment being cleaned. It is used to compare the corrosivity of various solvent systems and to determine the corrosivity of selected solvent systems under different conditions.

Test Method B is necessary because the corrosivity of a solvent system can be changed by the presence of ions in the solvent system. It is used to determine if the ions that might be present during a cleaning operation would significantly change the corrosivity of a solvent system.

Test Method C is necessary because the corrosivity of a solvent system under magnetite removal conditions can be different from the corrosivity in the absence of deposit. It is used to determine the corrosivity of the solvent system under magnetite removal conditions.

Test Method D is necessary because the presence or absence of deposits may affect the corrosivity of the solvent system. It is used to determine the corrosivity of solvent systems on deposit-coated specimens. These results are compared with results obtained from Test Method A to determine the effect of the deposit.
