Ductile iron pipes, fittings and accessories - Requirements and test methods for organic coatings of ductile iron fittings and accessories - Part 2: Thermoplastic acid modified polyolefin coating (TMPO)

To allow ductile iron pipe manufacturers and users of the product to apply TMPO linings and thereby comply with the relevant requirements of EN 545, EN 545, EN 969. This demonstrates innovation according to Annex I, by the use of non-traditional coating systems offering environmental and economic benefits. The TMPO linings meet the criteria expressed in EN 14901, except for those pertinent to fusion bonded epoxy chemistry. The linings are being used in other parts of the world eg Australia and New Zealand and have been incorporated in the recent AWWA C116/A21.16-15 publication. The current status for TMPO linings in EU amounts to a barrier to trade and does not support SME’s involved in the manufacture, lining and application of the material that offers human health benefits, as highlighted in the Annex I and II.

Cevi, fitingi in pribor iz duktilne železove litine - Zahteve in preskusne metode za zunanje organske prevleke fitingov in pribora iz duktilne železove litine - 2. del: Termoplastična zunanja prevleka iz poliolefina, modificiranega s kislino (TMPO)

Proizvajalcem in uporabnikom cevi iz duktilne železove litine omogoča uporabo termoplastične zunanje prevleke iz poliolefina, modificiranega s kislino (TMPO), in pri tem zagotavljanje skladnosti z ustreznimi zahtevami iz standardov EN 545, EN 545, EN 969. To pomeni inovacijo v skladu z dodatkom I na podlagi uporabe netradicionalnih premaznih sistemov, ki ponujajo okoljske in ekonomske koristi. Obloge iz termoplastične zunanje prevleke iz poliolefina, modificiranega s kislino, izpolnjujejo kriterije iz standarda EN 14901, razen tistih, ki se navezujejo na kemijo vezanega epoksija. Obloge se uporabljajo v drugih delih sveta, npr. v Avstraliji in na Novi Zelandiji, in so bile vključene v nedavno objavo standarda AWWA C116/A21,16-15. Trenutni status oblog iz termoplastične zunanje prevleke iz poliolefina, modificiranega s kislino, v EU pomeni oviro za trgovanje ter ne podpira malih in srednjih podjetij, vključenih v proizvodnjo, oblaganje in nanašanje materiala, ki ponuja koristi za zdravje ljudi, kot je poudarjeno v dodatkih I in II.
