This Standard specifies procedures for determining the resistance of copper-base alloys containing zinc to the form of corrosion termed ‘dezincification’, in two steps as follows:
(a) Alloys are categorized into two groups based on their chemical composition which is used to assess their susceptibility to dezincification.
(b) Alloys assessed to be resistant to dezincification on the basis ofchemical composition do not require testing. Alloys considered to be susceptible can be further evaluated by testing them under accelerated laboratory conditions after the completion of all manufacturing stages. Following this test and where the specified acceptance criteria are met,such alloys can also be regarded as resistant to dezincification.
