The properties which can be determined are<\/p>\n<p>&#8211;      the longitudinal tensile strength, and<\/p>\n<p>&#8211;      the percentage ultimate elongation.<\/p>\n<p>Method A uses, for the test piece(s), a longitudinal strip cut from a pipe.<\/p>\n<p>Method B uses a specified length of the full cross-section of the pipe.<\/p>\n<p>Method A is applicable to pipes with a nominal size of DN 50 or greater with circumferentially wound filaments, with or without chopped glass and\/or woven rovings and\/or fillers, and to centrifugally cast pipes. It is applicable to pipes with helically wound filaments with a nominal size of DN 200 or greater.<\/p>\n<p>Method B is applicable to all types of GRP pipe. It is usually used for pipes with a nominal size up to and including DN 150.<\/p>\n<p>Results from one method are not necessarily equal to the results derived from any of the alternative methods. However, all methods have equal validity.<\/p>\n<p>Annex A describes additional considerations for method B that have been found useful for the testing of thin-walled helically wound pipes and can be used to supplement the basic text.<\/p>\n<p>NOTE          This International Standard does not address the determination of longitudinal tensile modulus. Due to the multi-layer construction of many GRP pipes, the accurate measurement of strain, necessary for modulus determination, can be very difficult. If it is desired to determine longitudinal modulus, see ISO 527-4 and\/or ISO 527-5.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Plastics piping systems \u2014 Glass-reinforced thermosetting plastics (GRP) pipes \u2014 Test methods for the determination of the initial longitudinal tensile strength<\/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\/iso\/\"><b>ISO<\/b><\/a><\/td>\n<td>2016-02<\/td>\n<td>18<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":627168,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[349,2634],"product_tag":[],"class_list":{"0":"post-627155","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-23-040-20","7":"product_cat-iso","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\/627155","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\/627168"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=627155"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=627155"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=627155"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
