The pipe bends must conform to the requirements of DIN 16963 Part 5 or Part 25 *). For technical reasons the pipe bends may only be welded to pipes of the same series in accordance with DIN 8074 Part 1 or Part 2. Deviation from this requirement is allowed if tho wall thicknesses aro equal in the welding zone, Note: Instead of the designation “Hard Polyethylene (hard PE)”, the designátion “High density polyethylene (HDPE)” was adopted in accordance with DIN 7 728Part 1, April 1978 edition. a The previously used short designation “Hard Polyethylene (hard PE)“ may, however, continue to be used during the transitional period (e.g. the service life of the staraping tools for marking pipes and pipe elements). 2 Other relevant Standards DIN 1910 Part3 Welding; welding of plastics, methods ê DIN 8074 Part 1 Hard polyethylene (hard PE) pipes; type 1, dimensions?
