Moisten the probe sponge with tap water and slowly draw the probe over the impact area. The presence of cracks will be indicated by an audible alarm. NOTE 3—The copper sulfate solution will not perform properly on zinc-phosphate-treated metal unless the conversion coating cracks.
ASTM D2794 – 93(2010)
By gradually increasing the distance the weight drops, the point at which failure usually occurs can be determined. Interlaboratory agreement is improved when ranking is used astk place of numerical values.
