Creep of granulated loose-fil insulation - Test method and round robin test (NT TR 491)

NT TR 491

  • This report presents a proposal for a standardised method for creep tests and the necessary theoretical framework that can be used to describe creep of a granulated loose-fill material. Furthermore results from a round robin test are shown.

Insulation materials, granulated: Air permeability (NT BUILD 360)

NT BUILD 360

  • 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.

Thermal insulation material: Porous thickness (NT BUILD 359)

NT BUILD 359

  • 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).
