Polyurethane Foam ASTM Test Methods

General Information about ASTM Test Methods for rigid polyurethane foam

(ASTM D1621) Standard Test Method for Compressive Properties of Rigid Cellular Plastics - This test method describes a procedure for determining the compressive properties of rigid cellular materials, particularly expanded plastics, based on test machine crosshead motion.

(ASTM D1622) Standard Test Method for Apparent Density of Rigid Cellular Plastics - This test method covers the determination of both the apparent overall density and the apparent core density of cellular plastics. It is primarily intended for rigid cellular plastics.

(ASTM D1623) Standard Test Method for Tensile and Tensile Adhesion Properties of Rigid Cellular Plastics - This test method covers the determination of the tensile and tensile adhesion properties of rigid cellular materials in the form of test specimens of standard shape under defined conditions of temperature, humidity, and testing machine speed.

(ASTM D2126) Standard Test Method for Response of Rigid Cellular Plastics to Thermal and Humid Aging - This test method covers procedures for the thermal and humid exposure of rigid cellular plastics. Conditions used shall be agreed upon between the purchaser and the supplier.

(ASTM D2842) Standard Test Method for Water Absorption of Rigid Cellular Plastics - This test method covers the determination of the water absorption of rigid cellular plastics by measuring the change in buoyant force resulting from immersion under a 5.1-cm (2-in.) head of water for the specified immersion period for 96 h is standard.

(ASTM D2856) Standard Test Method for Open Cell Content of Rigid Cellular Plastics By the Air Pycnometer - This test method determines numerical values for open cells. It is a porosity determination, measuring the accessible cellular volume of a material. The volume occupied by closed cells is considered to include cell walls. Since any conveniently sized specimen can only be obtained by some cutting operation, a fraction of the closed cells will be opened during sample preparation and will be included as open cells.

(ASTM D6226) Standard Test Method for Open Cell Content of Rigid Cellular Plastics [Gas Pycnometer] - This test method determines numerical values for open cells. It is a porosity determination, measuring the accessible cellular volume of a material. The remaining volume is that occupied by closed cells and cell walls. Since any conveniently sized specimen can only be obtained by some cutting operation, a fraction of the closed cells will be opened by specimen preparation and will be included as open cells.

(ASTM D3576) Standard Test Method for Cell Size of Rigid Cellular Plastics - This test method covers the determination of the apparent cell size of rigid cellular plastics by counting the number of cell-wall intersections in a specified distance.

R-Value Test Methods

(ASTM C 518) Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus - This test method covers the measurement of steady state thermal transmission through flat slab specimens using a heat flow meter apparatus.

(ASTM C 177) Standard Test Method for Steady-State Heat Flux Measurements and Thermal Transmission Properties by Means of the Guarded-Hot-Plate Apparatus - This test method covers the achievement and measurement of steady-state heat flux through flat-slab specimens using a guarded-hot-plate apparatus. The method encompasses both the single-sided and the double-sided mode of measurement. Both distributed and line source guarded heating plate designs are included, in principle, in this test method. The reader should consult the standard practices on the single-sided mode of operation and on the line source apparatus for further details on these variations of the method.
