It defines the of applying the markings, on the body, on a flange, on an identification plate or any other location. When specified as a normative reference in a valve product or perance standard, this standard has to be considered in conjunction with the specified requirements of that valve product or perance standard. The marking requirements for plastic valves are not within the scope of this standard. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies including amendments. EN 736-1, Valves – Terminology - Part 1 Definition of types of valves.

When it is necessary to include descriptive words so as to properly define any supplementary markings see 4.3 or other markings see 4.4 then any such words shall be in the language of the manufacturer and/or one of the official CEN languages. 4.1.3Table 1 lists those items which shall be considered for inclusion in product or perance standards. Details of the markings are given in clause 5. 4.1.4Markings shall be located as detailed in 4.2, 4.3 and 4.4. Painted-on markings are not permitted. Where marking plates or identification plates are used, unless otherwise specified in product or perance standards, the material and of fixing shall be at the discretion of the manufacturer. All marking plates and identification plates and their means of fixing shall be in a material which is resistant to atmospheric corrosion. Marking plates shall also be suitable for the allowable temperature of the valve. 4.2 Mandatory markings 4.2.1Items 1 to 4 in Table 1 shall be marked on every valve and shall be integral markings or on a marking plate. If a valve has no defined PN or Class designation, items 7 and 9 in Table 1 are mandatory. See also 4.5.4. 4.2.2Items 5 and 6 in Table 1 shall be marked on those valves requiring these markings. See 5.5 and 5.6. 4.3 Supplementary markings Items 7 to 21 in Table 1 are optional unless otherwise specified in product or perance standard. The location of supplementary markings shall be determined by the manufacturer unless otherwise specified in the relevant product or perance standard. 4.4 Other markings A manufacturer having complied with the above requirements of this standard, and those of product or perance standards relevant to the individual types of valve is permitted to a mark any of the items in Table 1 additionally in a place other than that specified; e.g. if a marking is mandatory on the body or bonnet/cover it may also be repeated on the identification plate; b add to the markings specified, any technical and/or commercial references, providing that there is no risk of confusion between these markings and the markings in Table 1. For industrial valves coning to the requirements of the EU Directives stated in annex ZA, additional markings in accordance with 5.10 and 5.18 are required.
