10、 - Bst method for resistance to a short-terrn internal pressure without end thrust, published by the European Committee for Standardization (CEN). It is incorporated into BS 2782 Methods of testing plastics Part 11 Thmnmplasticspipes, fittings and valves, as Method 11235 : 1995, for association with
11、 related test methods for plastics materials and plastics piping components. This test method has been prepared for reference by other standards under preparation by CEN for specification of plastics piping systems and components. It has been implemented to enable experience of the method to be gain
12、ed and for use for other fresh applications. It is also for use for the revision or amendment of other national standards as practicable, but it should not be presumed to apply to any existing standard or specification which contains or makes reference to a different test method until that standard/
13、specification has been amended or revised to make reference to this method and adjust any requirements as appropriate. Warning note. This British Standard, which is identical with EN 803 : 1994, does not necessarily detail ali the precautions necessary to meet the requirements of the Health and Safe
14、ty at Work etc. Act 1974. Attention should be paid to any appropriate safety precautions and the method should be operated only by trained personnel.

22、ge 2 EN 803 : 1994 Foreword This standard was prepared by CEN/TC 155, Plastics piping systems and ducting systems. This standard is based on the International Standard IS0 2035 : 1974 Unplasticized poly(viny1 chloride) (PVC) moulded fittings for elastic sealing ring type joints for use under pressur
23、e - Pressure-res.istance test, published by the International Organization for Standardization (ISO). It is a modification of IS0 2035 : 1974 for reasons of applicability to other plastics materials and/or other test conditions and alignment with texts of other standards on test methods. The modific
24、ations are: - no material is mentioned; - test parameters, except those common to all plastics, are omitted; editorial changes have been introduced. - The material-dependent parameters and/or performance requirements are incorporated in the System Standard(s) concerned. No existing European Standard
25、 is superseded by this standard. This standard is one of a series of standards on test methods which support System Standards for plastics piping systems and ducting systems. This European Standard shall be given the status of a national standard, either by publication of an identical text or by end
26、orsement, at the latest by October 1994, and conflicting national standards shall be withdrawn at the latest by October 1994. According to the CENKENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany,
27、Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom. . 1 Scope This standard specifies a method for testing the resistance to internal hydrostatic pressure at 20 OC of any ijection-moulded thermoplastics fittings with elastic seal
28、ing ring type joints for thermoplastics pressure pipes having a nominal diameter, b) the period of time, t, that the test piece is subjected to pressure. 3 Apparatus 3.1 Pressurizing device, including thermostatic and/or environmental controls, capable of maintaining the specified hydrostatic pressu
29、re, p (see item a) of the note to clause 2), to within f 2,5 !%, for the specified period of time, t (see item b) of the note to clause 2), and of maintaining the test piece at (20 f 2) OC. 3.2 Supporting device, to compensate for the end thrust(s) resulting from the application of internal pressure
30、. 3.3 Pressure gauge, capable of checking conformity to the specified test pressure, p (see 3.1). Page 3 EN 803 : 1994 4 Test piece The test piece shall comprise an assembly of one or more pipe sections and fittings including at least one fitting of the type to be tested. Unless otherwise specified
31、in the referring standard, the section(s) of pipe to be connected shall have a length of three times d, with a minimum of 250 mm. They shall be capable of withstanding the test pressure, p, required by the referring standard. Assembling of the test piece shall be carried out in accordance with the m
32、anufacturers instructions. 5 Procedure In any convenient order cany out the following steps. a) Connect the end of one of the pipe sections of the test piece to the pressurizing device (see 3.1). b) Close by appropriate means the other end(s) of the test piece. c) Fill the test piece with water at (
33、20 f 2) OC, taking care to bleed off all internal air. Wait for at least 20 min after filling to ensure equalization of temperature to (20 I 2) OC. Remove any moisture from the outside surface of the test piece. Apply hydrostatic pressure progressively in such a way that the test pressure, p, is rea
34、ched in not less than 30 s and not more than 300 s. Maintain the test piece environment at (20 f 2) OC for the specified period, t, or until prior failure Maintain the pressure, p, for the specified period, t, checking by means of the pressure gauge that the pressure is within I 2,5 % and ensuring t
35、hat no leakage occurs at any area of the test piece unless prior failure occurs. If any area of the assembly other than a fitting under test shows failure (e.g. failure of another joint or a pipe bursting), start the test again, if necessary using other test piece elements. Maintain the pressure unt
36、il the assembly has shown constant leaktightness for the period, t, or until the fitting(s) fail(s), whichever occurs first. Record the results accordingly. occurs.
