The polymeric material used for stress design layers and all inner layers must be polyethylene (PE) and\/or crosslinked polyethylene (PE-X), in accordance with Annex A. The outer layers of metal multilayer pipes must be of either PE or PE-X.<\/p>\n<p>NOTE     For the purposes of ISO 18225:2012, PE-RT is considered as PE, while PE-X and adhesive layers are considered as thermoplastics materials.<\/p>\n<p>ISO 18225:2012 is applicable to systems intended to be operated at temperatures ranging from -20 \u00b0C to 40 \u00b0C. It is applicable to pipes in these systems having a nominal diameter up to and including 630 mm, and to the supply of gaseous fuels of categories D (natural gas) and E (LPG vapour and natural gas or LPG vapour) (see ISO 13623).<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Plastics piping systems \u2014 Multilayer piping systems for outdoor gas installations \u2014 Specifications for systems<\/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>2012-12<\/td>\n<td>24<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":600403,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[349,351,1083,2634],"product_tag":[],"class_list":{"0":"post-600392","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-23-040-20","7":"product_cat-23-040-45","8":"product_cat-75-200","9":"product_cat-iso","11":"first","12":"instock","13":"sold-individually","14":"shipping-taxable","15":"purchasable","16":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/600392","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\/600403"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=600392"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=600392"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=600392"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
