Plastics piping systems for the transport of water intended for human consumption - Migration assessment - Guidance on the interpretation of laboratory derived migration values

This Technical Report is applicable to plastics pipes, joints and fittings to be used for the transport of water intended for human consumption and raw water used for the manufacture of water intended for human consumption.
It gives guidance on:
a)   the number of successive migration periods to be carried out;
b)   how to interpret M values calculated from successive migration periods;
c)   a method for converting M values into values that reflect field use conditions;
d)   acceptance criteria for the duplicate M values obtained by testing in accordance with EN ISO 8795.

Kunststoff-Rohrleitungssysteme für den Transport von Trinkwasser für den menschlichen Verzehr - Bewertung der Migration - Anleitung für die Beurteilung von aus Laborversuchen abgeleiteten Migrationswerten

Dieser Technische Bericht ist auf Rohre, Formstücke und Verbindungen aus Kunststoff anwendbar, die zum Transport von Wasser für den menschlichen Verzehr und von Rohwasser, das zur Herstellung von Wasser für den menschlichen Verzehr vorgesehen ist, verwendet werden.
Er gibt Anleitung für:
a)   Anzahl durchzuführender aufeinander folgender Migrationsphasen;
b)   Art und Weise der Beurteilung der aus den aufeinander folgenden Migrationsphasen berechneten Migrationswerte;
c)   Verfahren zur Umwandlung von Migrationswerten in Werte, die Gebrauchsbedingungen widerspiegeln;
d)   Annahmekriterien für die bei der Prüfung nach EN ISO 8795 erhaltenen doppelt bestimmten Migrationswerte.

Systèmes de canalisations plastiques pour le transport d'eau destinée à la consommation humaine - Évaluation de la migration - Guide d'interprétation des valeurs de migration déterminées en laboratoire

Le présent Rapport Technique est applicable aux tubes, raccords et assemblages plastiques utilisables pour le
transport de l'eau destinée à la consommation humaine et de l'eau brute utilisée pour la production d'eau potable.
Il donne des indications sur :
a) le nombre de périodes de migration successives à effectuer ;
b) la façon d’interpréter les valeurs de M, calculées à partir des périodes de migration successives ;
c) une méthode permettant de convertir les valeurs calculées de M en valeurs reflétant les conditions d’utilisation
sur le terrain ;
d) les critères d’acceptation des contre-valeurs de M obtenues en effectuant des essais conformément à
l’EN ISO 8795.

Cevni sistemi iz polimernih materialov za transport pitne vode - Vrednotenje migracije - Navodilo za razlago laboratorijsko pridobljenih migracijskih vrednosti

To tehnično poročilo velja za polimerne pipe, spoje in fitinge za uporabo pri transportu pitne vode in neobdelane vode za uporabo pri proizvodnji pitne vode. Podaja navodila za: a) število zaporednih migracijskih obdobij za izvajanje; b) kako razlagati vrednosti M, izračunane iz zaporednih migracijskih obdobij; c) metodo pretvarjanja vrednosti M v vrednosti, ki odražajo pogoje terenske uporabe; merila sprejemljivosti za podvojene vrednosti M, pridobljene s preskušanjem v skladu z EN ISO 8795.
