Influence of materials on water for human consumption - Enhancement of microbial growth (EMG)

This European Standard specifies three methods for determining the ability of non-metallic materials to enhance the growth of micro-organisms.
This European Standard is applicable to those materials destined to be used under various conditions for the transport and storage of water intended for human consumption.
The standard allows for the testing of a single type of material, or a product in which only one material is in contact with water. It is unsuitable for use with assembled products where more than one material is exposed to water.
NOTE    The results given by each method are not directly comparable.

Einfluss von Materialien auf Wasser für den menschlichen Gebrauch - Vermehrung von Mikroorganismen

Influence des matériaux sur l'eau destinée à la consommation humaine - Stimulation de la croissance microbienne (SCM)

La présente Norme européenne spécifie des modes opératoires pour déterminer la capacité de matériaux non métalliques à favoriser la croissance de micro-organismes.
La présente norme s’applique aux matériaux destinés à être utilisés dans diverses conditions pour le transport et le stockage de l’eau destinée à la consommation humaine.
La norme prévoit de soumettre à essai des échantillons ne comportant qu’un seul type de matériau ou un produit dans lequel un seul type de matériau est en contact avec l’eau. Son utilisation ne convient pas aux produits assemblés dans lesquels plusieurs matériaux sont exposés à l’eau.

Vpliv materialov na pitno vodo - Spodbujanje mikrobiološke rasti

Ta evropski standard določa postopke za ugotavljanje zmožnosti nekovinskih materialov za spodbujanje rasti mikroorganizmov.
Ta standard se uporablja za materiale, ki so namenjeni uporabi v različnih pogojih za transport in skladiščenje pitne vode.
Standard omogoča preskušanje materiala enotnega tipa ali proizvoda, pri katerem je le en material v stiku z vodo. Ni primeren za uporabo s sestavljenimi proizvodi, pri katerih je vodi izpostavljen več kot en material.
