ASTM B489 – Standard Practice for Bend Test for Ductility of Electrodeposited and Autocatalytically Deposited Metal Coatings on Metals
Significance and Use
4.1 The routine measurement of the ductility of electrodeposited and autocatalytically deposited metal coatings can be useful in process control, especially when the electroplating process is used for decorative and engineering purposes.
1.1 This practice covers a test procedure for determining the ductility of electrodeposited and autocatalytically deposited coatings on sheet or strip basis metals. The purpose of the test is to determine the resistance of metal coatings to cracking during distortion.2
1.2 Test Methods E8 can be used if the coatings are too ductile and require mandrels too small to be practical.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
