Special racks may involve the use of conforming, auxiliary, bipolar electrodes, or nonconducting shields.

The size of the sample and the criteria of compliance are determined by the application of statistics.

Acid pickling of high strength steels shall be avoided. For some applications this requirement may be relaxed to allow for a small number of such defects per unit areaespecially if they are outside or on the periphery of the signi? This is particularly useful in automatic reel-to-reel applications in which dwell times are atm All non-gold metals, excluding potassium and sodium, are considered impurities and shall not be present in amounts greater than 0.

Deposit hardness should be determined on samples at plating conditions representative of actual production. Our extensive quality control measures throughout production include non-destructive testing in accordance with ASTM B to measure the thickness of the coating.
