This NORDTEST method describes how oxide thickness measurements and/or metallographic investigations (changes in carbide distribution) can be used to assess the temperature history of superheater and reheater tubes.
The aim of the test method is to provide an assessment of the corrosivity on carbon steel of combustion by-products from power and district heating plants before and after accelerated ageing at 40 °C in a measuring cell made for the purpose.
This test method specifies the procedure for determining the corrosion hazard on metals and metal fasteners from fire retardant treated wooden products after exposure in an accelerated laboratory environment.
This method is intended to evaluate the contribution to fire growth and smoke production under well ventilated conditions provided by a mattress, bed system etc. when subjected to a specified ignition source.
This document prescribes the classification requirements for the durability of the reaction to fire performance of fire-retardant treated wood-based products to be used in interior and/or exterior end use conditions.
The durability of a fire-retardant treatment of wood under exposure to accelerated weathering is covered by this standard. It is intended for fire-retardant treatment of wood by pressure impregnation, rather than simply by surface coating.
The test method comprises two independent parts, a low temperature phase test and a high temperature phase test. If a construction is to be evaluated according to either part, the two temperature phases may be combined into one test.
This test method specifies a procedure for determining the spontaneous ignition temperature Tc of samples of radius r, and, from these temperatures, the material parameters M and P from the equation where dc is a Frank-Kamenetskii critical parameter.
This NORDTEST method is intended to provide a basis for testing of proportioners for foam concentrates intended for use together with manual foam generation equipment. This test method includes both general requirements as well as performance tests.
This method is intended to be used for the evaluation of fire behaviour of upholstered furniture in full scale. The specimen is ignited by a specified ignition source and burns freely under well ventilated conditions.
