18、he 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of an identical text or by endorsement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest by June 2004. Annex A is norm
19、ative. This document supersedes EN 1277:1996. The modifications are: The deflection of the socket is now permitted to be greater than specified if by deflecting the spigot to the specified amount the socket, without applying load to it, is deflected to more than specified. The reason is that experie
20、nce with testing large diameter pipes in accordance with the 1996 version has shown that for some pipe designs a deflection of 10 % of the spigot resulted in a deflection larger than 5% of the socket without applying any load to it. This is the major reason for the revision. A support for the profil
21、es under the deflection device, see Figure 2, are specified in cases where there is a risk that the profiles are deflected too much when deflecting the spigot or socket. Figure 4 has been added to clarify the description of the deflection devices. The procedure for determining and applying the defle
22、ction has been described in more details, see 6.2. A number of editorial changes including a more logic order of the description of the test equipment and test procedure have been introduced. The material-dependent parameters and/or performance requirements are incorporated in the System Standard(s)
23、 concerned. This standard is one of a series of standards on test methods, which support System Standards for plastics piping systems and ducting systems. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Eu
24、ropean Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
