16、ited States1 3.Significance and Use3.1 Portable hardness testers are used for testing materialsthat because of their size,location or other requirements suchas test point are unable to be tested using traditional fixedinstruments.3.2 Portable hardness testers,by their nature,induce varia-tion that could influence the test results;therefore,hardnessmeasurements made in accordance with this test method arenot considered to meet the requirements of E10 or E18.Theuser should compare the results of t
