1.1These test methods cover the use of pendulum damping testers in the determination of hardness of organic coatings that have been applied to acceptably plane rigid surfaces, such as a metal or glass panel.
1.2Two test methods based on different pendulum types are covered as follows:
1.2.1Test Method A—König Pendulum Hardness Test.
1.2.2Test Method B—Persoz Pendulum Hardness Test.
1.3This standard is similar in content (but not technically equivalent) to ISO 1522.
1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5This standard does not purport to address all of the safety concerns, if any, associated with its use.
