The UK participation in its preparation was entrusted by Technical Committee PRI/88 (previously PRI/61), Plastics piping systems, to Subcommittee PRI/88/2 (previously PRI/61/2), Plastics piping systems for pressure applications, which has the responsibility to: — aid enquirers to understand the text; — present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; — monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. NOTE 2 It was decided not to proceed with the publication of prEN 13244-6, Recommended practice for installation and that existing national practices would be applicable. In the UK, in the absence of a British Standard covering installation, it is the opinion of Technical Committee PRI/88, Plastics piping systems, that reference to the Polyethylene Pipe Systems Manual1), a joint publication of WRc and BPF Plastic Pipes Group represents established UK practice. NOTE 3 Part 7 has been prepared as a CEN/TS, to allow further development. CEN/TS 13244-7 is not mandatory under the Public Procurement Directive. Attention is drawn to the following statutory regulations: Health and Safety at Work etc. Act 1974 and subsequent regulations. Attention is also drawn to any appropriate safety precautions. It is assumed in the drafting of a standard that the execution of its provisions is entrusted to appropriately qualified people. 1) WRc/BPF PLASTIC PIPES GROUP. Polyethylene Pipe Systems Manual.

Committee CEN/TC 155 "Plastics piping systems and ducting systems", the secretariat of which is held by NEN. 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of an identical text or by endorsement, at the latest by June 2003, and conflicting national standards shall be withdrawn at the latest by December 2004. For components which have conformed to the relevant national standard before December 2002, as shown by the manufacturer or by a certification body, the national standard may continue to be applied until the December 2004. It has been prepared in liaison with CEN/TC 165 "Waste water engineering". This European Standard is a Part of a System Standard for plastics piping systems of a particular material for a specified application. There are a number of such System Standards. System Standards are based on the results of the work being undertaken in ISO/TC 138 "Plastics pipes, fittings and valves for the transport of fluids", which is a Technical Committee of the International Organization for Standardization (ISO). They are supported by separate standards on test methods to which references are made throughout the System Standard. The System Standards are consistent with standards on general functional requirements and standards on recommended practice for installation. EN 13244 consists of the following Parts, under the general title Plastics piping systems for buried and aboveground pressure systems for water for general purposes, drainage and sewerage — Polyethylene (PE): — Part 1: General — Part 2: Pipes — Part 3: Fittings — Part 4: Valves (this standard) — Part 5: Fitness for purpose of the system — Part 7: Guidance for the assessment of conformity (to be published as a CEN/TS) NOTE It was decided not to publish a Part 6: Recommended practice for installation. Instead, existing national practices would be applicable. This Part of EN 13244 includes the following: — Bibliography System Standards for piping systems of other plastics materials used for the conveyance of water, drainage and sewerage under pressure include the following: prEN 14364, Plastics piping systems for pressure and non-pressure drainage and sewerage — Glass-reinforced thermosetting (GRP) plastics based on polyester resin (UP).

It is intended to be used for buried and above-ground pressure systems for water for general purposes, drainage and sewerage, including vacuum systems. Requirements and test methods for material and components, other than valves, are specified in EN 13244-1, EN 13244-2 and EN 13244-3. Characteristics for fitness for purpose are covered in EN 13244-5 and prCEN/TS 13244-7 gives guidance for the assessment of conformity. This Part of EN 13244 covers the characteristics of valves. 5 EN 13244-4:2002 (E) 标准分享网 www.bzfxw.com 免费下载 Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Sat Oct 13 11:48:12 GMT+00:00 2007, Uncontrolled Copy, (c) BSI 1 Scope This Part of EN 13244 specifies the characteristics of valves or valve bodies made from polyethylene (PE) intended for buried and above-ground pressure systems for water for general purposes, drainage and sewerage. It is also applicable for vacuum sewer systems. NOTE 1 Water for general purposes is not intended for human consumption and components conforming to this standard should not be used in systems conveying water for human consumption. For PE components intended for the conveyance of water intended for human consumption and raw water prior to treatment, see EN 12201 [1]. NOTE 2 Valves made from material other than polyethylene (PE) designed to (a) relevant standard(s) can be used in PE piping systems conforming to EN 13244 when they have relevant PE connection ends for butt fusion or electrofusion (see EN 13244-3). It also specifies the test parameters for the test methods referred to in this standard. In conjunction with other Parts of EN 13244 (see Foreword), it is applicable to PE valves, their joints and to joints with components of other materials intended to be used as follows:  buried in the ground;  sea outfalls;  laid in water;  above-ground, including pipes suspended below bridges;  a maximum operating pressure, MOP, up to and including 25 bar1);  an operating temperature of 20 °C as a reference temperature. NOTE 3 For applications operating at constant temperatures greater than 20 °C and up to 40 °C, see annex A of EN 13244-1:2002. EN 13244 covers a range of maximum operating pressures and gives requirements concerning colours and additives. NOTE 4 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes. This Part of EN 13244 covers valves for pipes with a nominal outside diameter dn ≤ 225 mm. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

The marking shall be such that it is legible without magnification. 10.2 Marking on valves If the mark is imprinted on the valve the marking shall not initiate cracks or other types of failure and that normal storage, weathering, handling, installation and use shall not affect the legibility of the marking. If printing is used, the colour of the printed information shall differ from the basic colour of the product. The minimum required marking shall conform to Table 5. NOTE Attention is drawn to the possible need to include CE marking when required for legislative purposes. Table 5 — Minimum required marking on valves Aspects required Mark or symbol Manufacturers name or trade mark Name or code Nominal diameter and pipe series/SDR Manufacturer’s information e.g. 110/S 5 or 110/SDR 11 a a In clear figures or in code providing traceability to production period within year and month and the production site if manufacturer is producing at different sites nationally and/or internationally. 10.3 Marking on a label Unless marked on the valve the information given in Table 6 shall be printed on a label, with one label per valve. The label shall be of sufficient quality to be intact and legible at the time of installation.

The packaging shall bear at least one label with the manufacturer's name, type and dimensions of the part, number of units and any special storage conditions. NOTE It is recommended to protect the spigot end by external caps. 16 Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Sat Oct 13 11:48:12 GMT+00:00 2007, Uncontrolled Copy, (c) BSI EN 13244-4:2002 (E) Bibliography [1] EN 12201, Plastics piping systems for water supply - Polyethylene (PE).

This requirement is specifically excluded from the scope of BS EN 681-1. For manufacturers wishing to demonstrate resistance of such products to biodegradation, a test is contained in BS 7874.
