4 Requirements
4.1 General
4.1.1 Where the requirements in a valve product or performance standard differ from those given in
this document, then the requirements of the product or performance standard apply.
4.1.2 Mandatory markings (see 4.2) are independent of language. 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 (English, French or German).4.1.3 Table 1 lists those items which shall be considered for inclusion in product or performance
standards. Details of the markings are given in Clause 5.The values PS and TSmax are valid for the design. TSmin indicates the lowest temperature limit at PS and
TSmax.In order to make the maximum/minimum allowable limits more explicit for the user of a valve, the
corresponding maximum/minimum allowable limits [either the standardized pressure/temperature
(p/t) rating, or the applicable values of PS, TSmax, TSmin, as applicable] shall also be indicated in the
accompanied operating manuals.4.1.4 Markings 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
performance standards, the material and method of fixing shall be at the discretion of th
