Materials shall be categorized as follows:
(a) Formed shapes Self-supporting shapes that have uniform or regularly repeating geometry on a scale small enough to permit determination of thermal resistance by physical measurement of heat flow through a representative area.
NOTES:
1 Formed shapes include panels, complete building elements such as walls or roofs, or other assemblies of different materials, which could include or combine bulk and IR reflective components internally but satisfy the requirement of small-scale uniformity. Formed shapes include bulk insulation materials with solid, cellular or other regular structure,(e.g. foamed or cellular plastics, insulating concretes, rammed earth, mud brick, wood-based products and rigid cellulose-based products such as cardboard, aerogels, cast resins and plasters). They also include fibrous materials not meeting the definition of ‘compressible’.
2 For guidance on thermal resistance measurement, see A ppendix A.
(b) Formed in situ Materials such as paints and other coatings, sprayed fibres, and sprayed or injected foams.
(c) Compressible Materials that can be compressed by 20% or greater at 2 kPa applied pressure, including segments and blanket, and usually supplied compression packaged (e.g. rock wool, glass wool, polyester fibre, wool and like materials). If the material cannot be compressed by 20% at 2 kPa, it shall be treated as ‘formed shapes’.
(d) Loose fills Materials and mixtures of materials that are granular or loose and that could compact under load (e.g. cellulose fibre, exfoliated vermiculite, expanded perlite, wool, glass wool, granulated cork, mineral wool, rock wool, slag wool, and expanded plastic beads or chips, granular minerals and earths).
(e) IR reflective Formed shapes and compressible materials that incorporate one or more external IR reflective surfaces and that have uniform or regularly repeating geometry on a scale small enough to permit determination of thermal resistance by physical measurement of heat flow through a representative area (e.g. IR reflective foil insulation, IR reflective claddings and facings of buildings and foil-faced pieces and blankets，where used in applications that satisfy the requirement of small-scale uniformity).
NOTE: Only the bulk insulation component R-value can be determined using the test methods detailed in this Standard. Any contribution from IR reflective airspaces external to the material should be calculated according to the methods detailed in AS/NZS 4859.2. AS NZS 4859.1 pdf free download.
