It applies to both metallic and non-metallic coatings on both metallic and non-metallic substrates. To employ this method, the atomic numbers or equivalent atomic numbers of the coating and the substrate need to differ by an appropriate amount. <br \/> WARNING: BETA-BACKSCATTER INSTRUMENTS USED FOR THE MEASUREMENT OF COATING THICKNESSES EMPLOY A NUMBER OF DIFFERENT RADIOACTIVE SOURCES. ALTHOUGH THE ACTIVITIES OF THESE SOURCES ARE NORMALLY VERY LOW, THEY CAN PRESENT A HAZARD TO HEALTH, IF INCORRECTLY HANDLED. THEREFORE, ALL RULES AND REGULATIONS OF LOCAL OR NATIONAL AUTHORITIES MUST BE OBSERVED. <br \/> NOTES: <br \/> 1 Characteristics of isotopes used with beta-backscatter gauges are given in Appendix A. <br \/> 2 The atomic numbers of some commonly used coatings and substrates are given in Appendix B.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Methods of test for metallic and related coatings &#8211; Local thickness tests &#8211; Beta-backscatter method<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/as\/\"><b>AS<\/b><\/a><\/td>\n<td>2001-12-11<\/td>\n<td>21<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":492846,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[442,2633],"product_tag":[],"class_list":{"0":"post-492833","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-25-220-40","7":"product_cat-as","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/492833","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/492846"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=492833"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=492833"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=492833"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
