7、11:Method 1150E:1997 ii BSI 03-1999 National foreword This British Standard reproduces verbatim ISO 11413:1996 and implements it as the UK national standard. The UK participation in its preparation was entrusted by Technical Committee PRI/61, Plastics piping systems and components, to Subcommittee P
8、RI/61/4, Methods of test for thermoplastics piping systems and components, 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 inform
9、ed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request. Cross-references This international standard is incorporated into BS 2782 Methods of testing plastics: Part 11: Thermoplastics
10、pipes, fittings and valves, as Method 1150E:1996, for association with related test methods for plastics materials and plastics piping components. British Standards which implement international or European publications referred to in dual numbered standards may usually be found in the BSI Standards
11、 Catalogue under the section entitled “International Standards Correspondence Index”, or using the “Find” facility of the BSI Standards Electronic Catalogue. Reference is made to ISO 4427, for which there is no identical British Standard because the corresponding British Standards are expected to be
12、 replaced by implementation of the collected Parts of EN 12201 when they are finalized. Reference is made to ISO 4437, ISO 8085-2 and ISO 8085-3, for which there are no identical British Standards because the corresponding British Standards are expected to be replaced by implementation of the collec
13、ted Parts of EN 1555 when they are finalized. WARNING NOTE. This British Standard, which is identical with ISO 11413:1996, does not necessarily detail all the precautions necessary to meet the requirements of the Health and Safety at Work etc. Act 1974. Attention should be paid to any appropriate sa
14、fety precautions and the method should be operated only by trained personnel. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself con
15、fer immunity from legal obligations.

17、 2006, Uncontrolled Copy, (c) BSI BS 2782-11:Method 1150E:1997 ii BSI 03-1999 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through IS
18、O technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates c
19、losely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least
20、 75 % of the member bodies casting a vote. International Standard ISO 11413 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 5, General properties of pipes, fittings and valves of plastic materials and their accessories
21、Test methods and basic specifications. Annex A to Annex C form an integral part of this International Standard. Annex D is for information only. Descriptors: Pipes (tubes), polyethylene, plastic tubes, pipe fittings, welded joints, tests, specimen preparation. Licensed Copy: London South Bank Univer

23、lectrofusion fittings (e.g. socket fittings such as couplers, or saddles). The assembly criteria specified include parameters such as ambient temperature, fusion conditions, fitting and pipe dimensions and pipe shape, taking into account the limiting service conditions specified by the relevant prod
24、uct standards. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
