The objective of the test method is to determine coefficients which describe the correlation between the linear air flow velocity through insulation materials and the pressure drop in insulation materials.
This Nordtest method is a laboratory test method for the determination of the thickness of highly porous thermal insulation materials. Thickness should be measured either on a whole sheet (leading dimension) or on a test specimen cut from the sheet (determination of thermal conductivity).
The resistance against CO2-penetration through concrete repairing materials and concrete protective coating is determined by an accelerated laboratory test on laboratory prepared samples by exposing the samples to carbon dioxide enriched air in order to evaluate the effect of concrete repairing materials. The depth of CO2-penetration is measured by the phenolphthalein method.
The chloride ion permeability of concrete repairing materials and concrete protective coating is determined by an accelerated laboratory test where a direct current voltage is applied between a steel rod embedded into the specimen and the specimen surface in order to evaluate the effect of concrete repairing materials.
The steady state chloride ion diffusion coefficient of concrete, mortar and cement based repair materials is determined by an accelerated laboratory test method. The amount of chloride vs. time passing through a porous material exposed to a constant direct voltage is measured after steady state is reached, in order to calculate a chloride diffusion coefficient.
This test method covers determination of the moisture content of building materials or building structures by moderation or slowing of fast neutrons where the neutron source and the thermal neutron detector both remain at the surface.
The purpose of this test method is to determine the moisture protection capability of a surface treatment on gypsum board. The testing is carried out with a view to estimate the moisture protection of layers applied to gypsum boards behind wall coverings consisting of ceramic tiles, since it cannot be taken for granted that such coverings - in particular the joints - are waterproof.
This NORDTEST method specifies a procedure for the determination of water absorption and desorption through paint coatings on building materials. The testing of water absorption/desorption is carried out by comparative testing of treated and untreated specimens.
This NORDTEST method describes how to measure the maximum deflection of floor joists when the floor is loaded with a 1.0 kN static, concentrated load. The deflection is used as a design criterion for determining maximum floor spans, taking into account the composite action between floor sheathing and joists.
The scope of this NORDTEST method is to calibrate electrical instruments for the measurement of relative air humidity. The test method is only for measuring equipment which gives off or takes up humidity to a limited extent.
This NORDTEST method specifies a test for puncturing under cumulative load. Mechanical stress on roofing varies from static long-term loads to dynamic short-term loads. This method represents an intermediate (semi-dynamic) load category.
This NORDTEST method specifies a test for puncture by impact on roof coverings. Mechanical stress on roofing varies from static long-term loads to dynamic short-term loads. This method represents a dynamic category of load where puncturing is caused by impact.
This NORDTEST method specifies an accurate method to determine the permeability coefficients for materials forming an attached coat when applied to a permeable substrate, e.g. wood. This method takes into account inherent cup effects in permeation experiments and eliminates the influence from the substrate during the test.
This NORDTEST method specifies a method for determination of the friction on sport floors when exposed to a dynamic, vertical, and rotating point load (i.e., simulating the load exerted by an athlete in a rotating movement on the floor).
Nordtest is a trademark of Nordic cooperation in conformity assessment. The emphasis of Nordtest is to develop, promote and innovate Nordic test methods and pre-normative activity. Nordtest endeavours to remove technical barriers to trade and promotes the concept: “Approved once, accepted everywhere”.
