Grunnlag for revisjon av prøvemetoden NT BUILD 307 (NT TR 510rev)

NT TR 510rev

  • The report accounts for judgements and tests that are carried out as a background for the revision of method NT Build 307 "Roof Coverings; Wind load resistance" originally published in November 1986. The goal of the revision was to define the method more precisely, to give a better description of the test rig and the routines concerning applying and testing.

Grunnlag for revisjon av prøvemetoden NT BUILD 306 (NT TR 507)

NT TR 507

  • The method NT Build 306 is a small-scale test method for determination of pull out strength of mechanical fasteners. On behalf of Nordtest a project has been carried out to create the basis to revise the method.

Roof coverings: Puncture, cumulative load (NT BUILD 336)

NT BUILD 336

  • 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.

Roof coverings: Puncture by impact (NT BUILD 335)

NT BUILD 335

  • 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.

Roof coverings: Strength of mechanical fasteners (NT BUILD 306)

NT BUILD 306

  • This method provides a way of finding the pullout strength of mechanical fasteners for roof coverings exposed to axial symmetric loading. Both static and pulsating loads are used. (In the case of unsymmetrical loadings, the strength must be evaluated separately).

Steep roofs - coverings : Tightness (NT BUILD 118)

NT BUILD 118

  • The present NORDTEST-method is intended primarely for testing the rain tightness of overlapping roofing materials on sloping roofs. The method is based on the principle of a combined rain- and windload and, if relevant, a pressure gradient over the roof covering.
