Význam a použití

4.1 This practice may be used as a method of controlling certain electroplating solutions. It is used to indicate the presence of pollution or some other adverse condition.

4.2 Ductility measurement is of particular value when electroplated parts are subjected to moderate stresses, such as when electroplated bumpers are bolted to a car or exposed to a wide range of fluctuating temperatures (thermal shock).

ASTM B490-2014 Standard Practice for Ductility Micrometer Bending Tests by Electrodeposition

Krok 1: Rozsah

1.1 This practice describes procedures for measuring the ductility of electrodeposited foils. 2

1.2 This practice is only applicable to the evaluation of electrical deposits with low ductility.

1.3 The ductility value obtained can only be considered semi-quantitative because the test has a significant operator dependence.

1.4 This practice is most applicable to internal process control, where measurements are always taken by the same operator. Changes in the ductility value can be used as an indication of possible changes in an electroplating solution.

1.5 Hodnoty vyjádřené v jednotkách SI se považují za standardní hodnoty. V této normě nejsou zahrnuty žádné další měrné jednotky.

1.6 This standard is not intended to address safety concerns, jestli nějaký, spojené s jeho užíváním. Je odpovědností uživatelů této normy zavést vhodné bezpečnostní a zdravotní postupy a určit použitelnost regulačních omezení před jejím použitím..
