This Standard specifies the requirements and test methods for the construction, the safety and the rational energy usage for heating boilers (standard-heating and low temperature boilers) fired by liquid fuels from steel and cast iron with burners according to the relevant burner standards up to a nominal heat output of 10 MW. They are operated, either with negative pressure (natural draught boiler) or with positive pressure (pressurised boiler) in the combustion chamber, in accordance with the boiler manufacturer’s instructions Boilers in accordance with this European Standard are designed for the heating of central heating installations in which the heat carrier is water, and the maximum allowable operating temperature of which is up to 110 \u00b0C and the maximum safety temperature limiter of 120 \u00b0C. The maximum allowable operating pressure is 10 bar. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of COUNCIL DIRECTIVE 92\/42\/EEC of 21 May 1992 on efficiency requirements for new hot-water boilers fired with liquid or gaseous fuels. The relationship with the EC-Directive is described in the informative Annex ZA in this European Standard.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":{"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":""},"product_brand":[],"product_cat":[175],"product_tag":[],"class_list":["post-161328","product","type-product","status-publish","product_cat-tse","first","instock","purchasable","product-type-simple","entry","content-bg","loop-entry"],"taxonomy_info":{"product_cat":[{"value":175,"label":"TSE"}]},"featured_image_src_large":false,"author_info":[],"comment_info":"","_links":{"self":[{"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/product\/161328","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/media?parent=161328"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/product_brand?post=161328"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/product_cat?post=161328"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/product_tag?post=161328"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
