Applicable Standards for Thermal Conductivity Meters

A thermal conductivity meter is used to measure the thermal conductivity of homogeneous, plate-like materials such as foamed concrete, mortar, plastics, rubber, glass, fibers, polystyrene boards, extruded polystyrene (XPS) boards, hollow glass, wood panels, and various insulation materials. It can also test granular, loose, and soft materials. These instruments are widely applied in manufacturers of heat-resistant and insulation materials, quality inspection and energy-efficiency testing agencies, as well as universities and research institutes. Applicable standards include: - GB/T 10294-2008: Steady-state thermal resistance and related properties of thermal insulation materials. - GB/T 3399-1982: Test method for thermal conductivity of plastics — Guarded hot plate method. - GB/T 10801.1-2002: Thermal insulation — Expanded polystyrene (EPS) foam plastics; specifies the measurement of thermal conductivity for rigid polyurethane foam materials. - GB/T 10801.2-2002: Thermal insulation — Extruded polystyrene (XPS) foam plastics; specifies the measurement of thermal conductivity for XPS foam plastics. - GB/T 3139-2005: Test method for thermal conductivity of fiber-reinforced plastics. - GB/T 17794-2008: Flexible elastomeric foam thermal insulation products. Selecting a thermal conductivity meter that complies with these standards helps ensure reliable measurements across a wide range of construction and industrial materials, supporting product development, quality assurance, and energy-efficiency evaluation.
