| Title | Joints for the connection of steel tubes and fittings for the conveyance of water and other aqueous liquids |
| Work Item Number | EC110107 |
| Abstract/Scope | This European Standard specifies a range of jointing methods for connecting low alloy steel tubes and steel tubes and fittings for use with aqueous liquids. The following specific joint types are covered by this document: butt welded joints, welded spigot and socket (or sleeve joints), welding collars, flange joints, threaded joints, spigot and socket joints with seal and mechanical couplings. This European Standard specifies requirements for the strength and integrity of the joints and the testing of the joints. This European Standard does not specify the requirements for the tubes or the fittings. This European Standard is suitable for joints intended for the conveyance of water for human consumption, after an appropriate coating has been applied. This European Standard is not intended for use in heating networks where elevated temperature properties are required. Flexible joints which permit significant angular deflection, both during and after installation and which can accept slight offset of the centre line, are not covered by this European Standard. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
In the case of undated standard, a link to the last dated version is provided.
In the case of series, a link to each standard identified in the series is provided.
We also invite you to check (via the website) whether corrigenda and/or amendments shall be read in conjunction with the main standard.
(7) This list of bibliographic references, which is provided for homegrown standards only, is purely indicative and was retrieved automatically using available XML files. It is limited to publications that have been published in the XML format. For standards that are not homegrown, the corresponding international standard should be consulted.
