A local increae in wall thickne of up to + 0,2 i permiible for up to 10 mm, and of up to 0,15 for greater than 10 mm. The mean value hall, however, remain within the given limit deviation. 7 Allowable working preure 7.1 Pipe conveying water The allowable working preure value, p, in N/mm 2, ha been calculated a follow from the induced tre, the pipe erie number and the afety factor (cf. DIN 8075): p = σ S SF where i the induced hydrotatic tre, taken from the reference curve in DIN 8075; S i the pipe erie number, taken from ISO 4065; SF i the afety factor. 7.2 Pipe conveying other fluid Where pipe are to convey fluid which may be hazardou if handled incorrectly, the cutomer hould contact the pipe manufacturer.

Explanatory note With regard to the pecification for outide diameter, thi tandard correpond to ISO 161-1, with regard to the pecification for wall thickne, it correpond to ISO 4065, and with regard to tolerance on outide diameter, circularity and wall thickne, it conform to ISO Nominal preure (PN) i no longer ued for pipe deignation in baic tandard for platic pipe. However, for the purpoe of comparion, table A.1 correlate the old PN value with the S and SDR value. The wall thickne,, of pipe of pecial dimenion i to be calculated on the bai of known internal preure a follow: = p d SF 2σ + p where p i the allowable working preure, in N/mm 2 ; d i the nominal outide diameter, in mm; i the induced hydrotatic tre, a in DIN 8075; SF i a afety factor. It hould be noted that the pipe outide diameter were elected from a preferred number erie. 1 ) The deignation of MFR or MVR determined a in ISO 1133, tet condition T, i a follow: 003: over 0,2 up to 0,4 g/10 min; 005: over 0,4 up to 0,7 g/10 min; 010: over 0,7 up to 1,3 g/10 min; 020: over 1,3 up to 3,0 g/10 min.

The nominal ize and allowable working preure to be ued in particular application are to be included in the appropriate product tandard or other applicable technical rule. According to current knowledge of the long-term tability of polyethylene, it can be aumed that pipe conveying water are capable of reiting the preure given in table 5 to 13.
