The procedure is applicable to the twelve non- and mono-ortho PCB designated by the WHO. It is optimised to measure PCB concentrations of about 0,01 ng WHO-TEQPCB\/m3. In addition to the 12 non- and mono-ortho-PCB the present document is also applicable to measure further PCB-congeners like the marker PCB 28, 52, 101, 138, 153, 180. This document specifies a framework of quality control requirements which have to be fulfilled by any PCB sampling, extraction, clean-up, identification and quantification methods to be applied. As a result of their similar chemical behaviour PCBs, as shown in the validation campaign, can be sampled from stationary sources together with the PCDDs\/PCDFs. Therefore it is possible to measure PCBs together with PCDDs\/PCDFs by applying EN 1948 Part 1, Part 2, Part 3 and Part 4. The complete sampling procedure is described in the EN 1948-1. Each of the three sampling methods of EN 1948-1 can be combined with the methods described in this document to complete the measurement procedure. EN 1948-1 is an integral part of the complete measurement procedure and is necessary for the determination of PCBs. This document contains the Amendment 1 (approved by CEN on 21 October 2013) to DIN EN 1948-4:2010-12, providing assistance in case of co-elution problems of PCB 127 and PCB 105.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Stationary source emissions &#8211; Determination of the mass concentration of PCDDs\/PCDFs and dioxin-like PCBs &#8211; Part 4: Sampling and analysis of dioxin-like PCBs<\/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\/din\/\"><b>DIN<\/b><\/a><\/td>\n<td>2014-03<\/td>\n<td>67<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":534649,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[206,2635],"product_tag":[],"class_list":{"0":"post-534634","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-13-040-40","7":"product_cat-din","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\/534634","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\/534649"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=534634"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=534634"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=534634"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
