This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibilit

This European Standard shall b
15、e given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 1999, and conflicting national standards shall be withdrawn at the latest by July 1999. According to the CEN/CENELEC Internal Regulations, the national standards organizatio
16、ns of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This standard is based on t
17、he test method described in 6.2.1 of ISO 4435:1991, Unplasticized poly(vinyl chloride) (PVC-U) pipes and fittings for buried drainage and sewerage systems Specifications, prepared by the International Organization for Standardization (ISO). It is a modification of ISO 4435:1991 for reasons of applic
18、ability to other plastics materials and/or other test conditions and alignment with texts of other standards on test methods. The modifications are: editorial changes have been introduced; the possibility of specifying the position from which the fitting shall be dropped is introduced; assessment of
19、 the effect of the test impact on watertightness is introduced. The material-dependent parameters and/or performance requirements are incorporated in the System Standard(s) concerned. This standard is one of a series of standards on test methods that support System Standards for plastics piping syst
20、ems and ducting systems. Contents Page Foreword 2 1 Scope 3 2 Principle 3 3 Apparatus 3 4 Test pieces 3 5 Conditioning 3 6 Procedure 3 7 Expression of results 4 8 Test report 4Page 3 EN 12061:1999 BSI 07-1999 1 Scope This standard specifies a method for testing the impact resistance of fittings by d
21、ropping them onto 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 disturbance as a result of the test. This standard is applicable to fittings made
22、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 onto a rigid surface. After impact, the fitting is inspected for any cracks visible without magnification. In the case of fitti
23、ngs with separate fixing elements, e.g. for seal retention, these elements are inspected for any permanent disturbance that could cause loss of watertightness. NOTE It is assumed that the following test parameters are set by the standard making reference to this standard: a) test temperature (see cl
24、ause 3); b) sampling procedure and frequency (see clause 4); c) conditioning time and temperature as applicable (see clause 5); d) the height through 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 conditi
25、ons for assessment of watertightness (see clauses 6 and 7). 3 Apparatus 3.1 Refrigerator or liquid bath, capable of maintaining the conditioning temperature within 28C. 3.2 Temperature-controlled environment, capable of maintaining the test temperature within 28C. 3.3 Test base, comprising a solid f
26、loor 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. 4 Test pieces 4.1 Test piece form The test piece shall comprise a
27、sample fitting complete, where applicable, with the sealing element and any associated means of fixing element(s) in place. 4.2 Sampling The sampling procedure and frequency shall be as specified in the referring standard. 4.3 Number Unless otherwise specified in the referring standard, the number o
28、f 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 the refrigerator, liquid bath or temperature-controlled environment (3.1 and 3.
29、2)a t the specified test temperature for at least the applicable minimum period given in Table 1, unless otherwise specified in the referring standard. Table 1 Minimum conditioning period Wall thickness e Minimum conditioning period mm h e 630: 60 Temperature controlled environment (3.2) with refrig
30、erator or liquid bath in the same environment 60 6.2 Release the fitting from the specified drop height in such an attitude that the specified point of impact hits the test base. NOTE The position from which the fitting shall be dropped in order to hit the specified impact point, may be decided by p
31、reliminary testing with each specific fitting type. 6.3 Inspect each fitting for and record the presence and positions of any cracks or splits visible without magnification. Disregard any surface scratches, scuffing or chipping of edges which may occur during the test. Assess the condition and/or as
32、sembly of the test piece for watertightness as necessary using the applicable test method(s) as specified by the referring standard to express the result in accordance with clause 7.Page 4 EN 12061:1999 BSI 07-1999 7 Expression of results 7.1 Unless otherwise specified in the referring standard, if
33、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 and the element can be restored manually to its correct position, e.g. to give a watertight joint, and the co
34、ndition 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 in such a way that watertight jointing is achieved, then express the result as “Damage”. 8 T
35、est report The test report shall include the following information: a) a reference to this standard and to the referring standard; b) complete identification of the fitting under test; c) the test temperature; d) the height from which the fitting(s) was (were) dropped; e) the point of impact; f) for
36、 each test piece, the results of the test and any associated information; g) any factors which may have affected the results, such as any incidents or any operating details not specified in this standard; h) the date of the test.blankBS EN 12061:1999 BS 2782-11: Method 1108D:1999 BSI 389 Chiswick Hi
