Guidelines for evaluating in-service creep damage (NT TR 302)

NT TR 302

  • To indicate safe life or re-evaluation periods for high-temperature components, assessment based on measured creep cavitation damage is used worldwide. To interpret the observed damage unambiguously requires evaluation of the extent of damage on a unique, clearly defined and accepted scale. The presently available European damage scales in the guidelines NORDTEST NT TR 170 and VGB-TW 507 provide reference micrographs for a range of creep damage in the most common high-temperature steels. However, these guidelines differ in their stated and implicit definitions of a given class (extent) of damage, although both guidelines are nominally based on the same original Neubauer scale of creep damage.

Gypsum and silicate boards: Moisture conditions characterised by electrical resistance (NT BUILD 441 - Edition 2)

NT BUILD 441

  • This NORDTEST method describes a procedure for in-situ characterisation of the moisture conditions in gypsum and calcium silicate boards, e.g. bathroom walls. This is expressed by the relative humidity of the boards, which is important in relation to gluing properties, strength, formation of cracks etc. The measurements are carried out by means of electrical moisture meters. The method is based on the observation that the electrical resistance between two electrodes punched into a piece of board is a function of the moisture content of the board.
