BS EN 1555-1 The pipes, ftings and valves shall be made of polyethylene compound conforming to this document.
The compound shall be made by adding to the polyethylene base polymer only those additives, pigments or carbon black, necessary for the manufacture of pipes, fttings and valves conforming to EN 1555-2, EN 1555-3 ;or prEN 1555-4, as applicable, and for their fuseability, storage and use.
All additives used shall take into account national legislation.
The colour of the compound shall be yellow (PE 80),orange (PE 100), or black (PE 80 and PE 100). The carbon black used in the production of black compound shall have an average (primary) particle size of 10 nm to 25 nm.
In some countries pipes made out of non-pigmented compound in conjunction with an external peelable layer are permitted, providing the compound conforms to the requirements of this document. If this is allowed in a country, this should be clearly stated in the national foreword.
The compounds conforming to Table 1 shall be fusible. This shall be demonstrated by the compound manufacturer for each compound of his own product range by checking that the requirement for the failure mode in a tensile test given in Table 3 is fulfilled for a butt fusion joint prepared by using the parameters as specified in AnnexA of Iso 11414:2009 at an ambient temperature of (23土 2) °C from pipes both manufactured from that compound.
Compounds conforming to Table 1 are considered fusible to each other. If requested, the compound manufacturer shall demonstrate this by checking that the requirement for the failure mode in a tensile test given in Table3 is fufilled for a butt fusion joint prepared by using the parameters as specified in Annex A of ISO 11414:2009 at an ambient temperature of (23土2)。C from two pipes manufactured from the compounds from his own range covered by this request.BS EN 1555-1 pdf download.
