Dimensions in mm 1 Field of application This standard specifies requirements for high-density polyothylene (PE-HD) fittings to be joined with PE-HD pipes as specified In DIN 8074 of MFI groups 005 and 010*). Where fittings are to be welded to pipes of other MFI groups, verification of weldability shall be provided. These fittings shall also comply with the requirements specified in DIN 16963 Part 5. 2 Dimensions and designation Fittings are not expected to conform to the designs illustrated here; compliance Is only required in the case ofthe dimen- sions specified.

[]) a) The status of tho standard le no longer that of a preliminary standard. b) PE-HD is no longer classified into type 1 and type 2. c) The specification for 45º branches (type A 45) has been deleted. d) The dimensions have been amended. e) The standard designatlon has boon changod. Explanatory notes This standard has been prepared by Subcommittee 504.4 Kunststoff-Fittings fr Rohre aus Thermoplasten ofthe Normenauss- chuB Kunststotfo and, in contrastto the previous edition, takes Into account the work ofISO/TC138/WG 9. Instead of specifying different dimensional systems, this standard establishes a basic system based on minimum dimensions,which leaves room for future developments.
