Methods of test for resistance to air and water penetration - Permeable walling constructions (water penetration) Ingestion-build-260237 usage of appliances and internal1 Scope This Part of this British Standard specifies methods of test for measuring the resistance to water penetration of permeable walling constructions without open joints under static air pressure. The methods are applicable to constructions which can be built in or fixed into a rigid steel frame by means of which the wall panel can be transported and secured to the pressure box test equipment. The first method is also applicable to walling
