This is the most direct international equivalent. Many impact testers are sold with dual certification to both ASTM D2794 and ISO 6272-2.
The standard equipment, often called a , consists of the following components: astm d2794 pdf

A cylindrical steel weight containing a spherical head. The standard specifies a weight of either 2.0 lb (0.91 kg) or 4.0 lb (1.81 kg). The spherical head typically has a diameter of 0.625 inches (15.9 mm) or 0.500 inches (12.7 mm). The standard specifies a weight of either 2
A softer metal substrate deforms more deeply, stretching the coating further and increasing the likelihood of failure.
A copper sulfate acidic solution (which deposits copper onto exposed steel substrates where the paint cracked). A pinhole detector or electrical porosity test. Step 5: Finding the Failure Threshold
