EN 16436-1:2014+A1:2015 (E) 3 European foreword This document (EN 16436-1:2014+A1:2015) has been prepared by Technical Committee CEN/TC 181 “Dedicated liquefied petroleum gas appliances”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2016, and conflicting national standards shall be withdrawn at the latest by June 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document includes Amendment 1 approved by CEN on 2015-10-01. This document supersedes EN 16436-1:2014. The start and finish of text introduced or altered by amendment is indicated in the text by tags !". This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16436-1:2014+A1:2015 (E) 4 1 Scope This European Standard specifies the characteristics and performance requirements for tubing and hoses made of either rubber or plastics for use with commercial propane and commercial butane and mixtures thereof, in the vapour phase, for connection of appliances, from: — pressurized gas container to a regulating device, — pressurized gas container to an appliance, — regulating device to an appliance, and — regulating device to installation pipework, in environments of a temperature range from –30 °C to +70 °C. Working pressures are from 0 bar to 30 bar. Three classes are defined in Table 1 according to the maximum working pressures and minimum ambient temperatures. This European Standard only covers the tubing or hose part of assemblies. The assemblies themselves will be covered by EN 16436-2. This European Standard does not apply to hoses for: — welding purposes (see EN ISO 3821, EN 1327); — propulsion purposes; — LPG transfer purposes (see EN 1762). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

[SOURCE: ISO 9162] 3.2 commercial propane hydrocarbon product composed predominantly of propane and/or propene Note 1 to entry: The remaining part can consist mainly of ethane/ethene and butane/butene isomers. [SOURCE: ISO 9162] 3.3 tubing single core of plastic or rubber with no reinforcement or cover 3.4 hose rubber or flexible thermoplastic lining with a reinforcement made of natural or synthetic textile material applied either spirally wound or braided, and a flexible rubber or thermoplastic outer cover 4 Classification of tubing and hose One class of tubing and two classes of hose are specified in Table 1 depending on the maximum working pressure and minimal ambient temperatures. Table 1 — Classification of tubings and hoses Class Maximum working pressure bar Minimum ambient temperature °C 1 (tubing) 0,2 -20 2 (hose) 10 -30 3 (hose) 30 SIST EN 16436-1:2014+A1:2016



EN 16436-1:2014+A1:2015 (E) 6 NOTE Classes 1 and 2 are usually used downstream of a pressure regulating device. 5 Materials and construction of tubing and hoses Class 1 tubing shall be made of rubber or thermoplastic material. Class 2 and class 3 hoses shall comprise a — rubber or thermoplastics lining; — reinforcement of natural or synthetic fibres applied either spirally wound or braided; — rubber or plastics cover. The outer cover may be pricked to allow any gas trapped between the inner lining and outer cover to be released. The surface colour of the tubing or hose shall be: - orange (see Figure 1a); or - black with the marking above, on, or below a continuous orange line of 5 mm minimum width (see Figure 1b); or - white for classes 1 and 2 with the marking above, on, or below a continuous orange line of 5 mm minimum width (see Figure 2).
