11、oreword 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 ISO technical committees. Each member body interested in a subject for which a te
12、chnical 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 closely with the International Electrotechnical Commission (IEC) on all matters
13、of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated
14、 to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible f
15、or identifying any or all such patent rights. ISO 13263 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 1, Plastics pipes and fittings for soil, waste and drainage (including land drainage).

16、3:2010INTERNATIONAL STANDARD ISO 13263:2010(E) ISO 2010 All rights reserved 1Thermoplastics piping systems for non-pressure underground drainage and sewerage Thermoplastics fittings Test method for impact strength 1 Scope This International Standard specifies a method for testing the impact resistan
17、ce of fittings by dropping them on to a rigid surface. For a fitting with seal-retaining components, such as seal-retaining caps or rings, the method includes assessment of the watertightness of the fittings when the fixing elements show damage as a result of the test. This International Standard is
18、 applicable to fittings made from thermoplastics materials intended to be used for buried and above-ground applications. 2 Principle The impact resistance of a fitting is tested by dropping the fitting on to a rigid surface. After impact, the fitting is inspected for any cracks visible without magni
19、fication. In the case of fittings with separate fixing elements, for example for seal retention, these elements are inspected for any permanent damage that could cause loss of watertightness. NOTE It is assumed that the following test parameters are set by the referring standard: a) test temperature
20、 (see Clause 3); b) sampling procedure and frequency (see Clause 4); c) conditioning time and temperature, as applicable (see Clause 5); d) the height from which the test piece is to be dropped (see Clause 6); e) the point of impact that is to hit the test base when dropped (see Clause 6); f) test c
21、onditions for assessment of watertightness (see Clauses 6 and 7). 3 Apparatus 3.1 Refrigerator or liquid bath, capable of maintaining the conditioning temperature within 2 C. 3.2 Temperature-controlled environment, capable of maintaining the test temperature within 2 C. 3.3 Test base, comprising a s
22、olid floor made of concrete or stone at least 100 mm thick or, alternatively, a slab of concrete with a minimum thickness of 100 mm and a mass at least 20 times that of the test piece. The surface shall be rigid, flat, smooth and horizontal. BS ISO 13263:2010ISO 13263:2010(E) 2 ISO 2010 All rights r
23、eserved4 Test pieces 4.1 Test piece form The test piece shall comprise a sample fitting complete, where applicable, with the sealing element and any associated means of the fixing element(s) in place. 4.2 Sampling The sampling procedure and frequency shall be as specified in the referring standard.
24、4.3 Number Unless otherwise specified in the referring standard, the number of test pieces shall be five for sizes up to and including 200 mm, and three for sizes greater than 200 mm. 5 Conditioning Determine and measure the maximum wall thickness, e, of the sample fitting. Place the test piece in t
25、he refrigerator, liquid bath or temperature-controlled environment (3.1 and 3.2) at the specified test temperature for at least the applicable minimum period given in Table 1, unless otherwise specified in the referring standard.

27、of impact hits the test base. The position from which the fitting shall be dropped in order to hit the specified impact point may be decided by preliminary testing with each specific fitting type. 6.3 Inspect each fitting for, and record the presence and positions of, any cracks or splits visible wi
28、thout magnification. Disregard any surface scratches, scuffing or chipping of edges that may occur during the test. Assess the condition and/or assembly of the test piece for watertightness using the applicable test method(s) specified in the referring standard to express the result in accordance wi
29、th Clause 7. 7 Expression of results 7.1 Unless otherwise specified in the referring standard, if the fitting shows no cracks through the wall and the condition in 7.2 is conformed to, express the result as “No damage”. 7.2 If, during the test, the fixing element jumps off the fitting body but can b
30、e restored manually to its correct position, e.g. to give a watertight joint, and if the condition in 7.1 is conformed to, express the result as “No damage”. 7.3 If the fitting shows cracks through the wall or if the fixing element has jumped off the fitting without the possibility of restoring it i
31、n such a way that watertight jointing is achieved, express the result as “Damage”. 8 Test report The test report shall include the following information: a) a reference to this International Standard, i.e. ISO 13263:2010, and the referring standard; b) complete identification of the fitting under te
32、st; c) the test temperature; d) the height from which the fitting(s) was (were) dropped; e) the point of impact; f) for each test piece, the results of the test and any associated information; g) any factor that could have affected the results, such as any incident or any operating detail not specif
33、ied in this International Standard; h) the date of the test.
