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

This Prestandard 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:
1) number of successive migration periods to be carried out;
2) how to interpret M values calculated from successive migration periods;
3) a method for converting M values into values that reflect field use conditions;
4) acceptance criteria for the duplicate M values obtained by testing in accordance with EN ISO 8795.

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

Diese Vornorm 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.
Sie gibt Anleitung für
1) Anzahl durchzuführender aufeinander folgender Migrationsphasen;
2) Art und Weise der Beurteilung der aus den aufeinander folgenden Migrationsphasen berechneten Migrationswerte;
3) Verfahren zur Umwandlung von Migrationswerten in Werte, die Gebrauchsbedingungen widerspiegeln;
4) 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 - Evaluation de la migration - Guide d'interprétation des valeurs de migration déterminées en laboratoire

La présente Prénorme 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.
Elle 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.

This European Prestandard (ENV) was approved by CEN on 22 July 2001 as a prospective standard for provisional application.
The period of validity of this ENV is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.
