The following types may be specified for Method 1:
Type 1 Low Temperature Nitric Acid with Sodium Dichromate
Type 2 Medium Temperature Nitric Acid with Sodium Dichromate
Type 3 High Temperature Nitric Acid with Sodium Dichromate
Type 4 40% Nitric Acid for Free Machining Steels
Type 5 Anodic, for High Carbon Martensitic Steels
Type 6 Low Temperature Nitric Acid
Type 7 Medium Temperature Nitric Acid
Type 8 Medium Temperature, High Nitric Acid Concentration
Where no type is specified, the processor may use any of the listed types that meet the requirements given herein.
Passivation verification classes are as follows:
The following types of parts shall be selected for testing in accordance with 4.3.1
Fasteners, including nuts, bolts, washers, rivets and related hardware where a test frequency is not defined in the procurement documents.
Standard parts defined by drawings labeled AN, MS, NAS or similar where frequency of test is not otherwise defined.
When specified by purchaser.
Frequency of corrosion testing shall be one part per lot.
Frequency of testing shall be on a periodic basis.
Parts for which AMS-QQ-P-35 or QQ-P-35 is specified shall be acceptance tested in accordance with 4.3.4.
When no class is specified and neither 22.214.171.124 nor 126.96.36.199 apply, class 2 shall apply.
