Wall coverings and bushings for water pipes and taps in bathrooms: Watertightness (NT BUILD 448)

Abstract

Evaluation of the watertightness between wall coverings and bushings for water pipes and taps in bathrooms on the basis of tests with small test pieces.

SCOPE

The scope of this Nordtest method is to test and evaluate the watertightness between watertight layers in wall coverings for bathrooms and bushings for water pipes and taps when exposed to water and mechanical actions in bathrooms in ordinary dwellings.

FIELD OF APPLICATION

The method is applicable to all kinds of bushings for water pipes and taps and all watertight layers intended for the protection of non-moisture resistant materials against water penetration and accumulation when exposed to water and mechanical forces to be expected in bathrooms in ordinary dwellings.
