Standard Test Method for Strength Properties of Adhesively Bonded Plastic Lap-Shear Sandwich Joints in Shear by Tension Loading
Abstract: 4.1 Due to the increased use of adhesively bonded plastics as a result of the inherent advantages afforded by bonded rather than mechanically fastened joints, particularly the alleviation of stress risers and stress cracking, ... -
Standard Test Method for Wind Resistance of Steep Slope Roofing Products (Fan-Induced Method)
Abstract: 5.1 Most steep slope roofing products that have demonstrated wind resistance by this test have also performed well in use. Natural wind conditions differ with respect to intensity, duration, and turbulence; these conditions ... -
Standard Test Method for Specific Gravity, API Gravity, or Density of Cutback Asphalts by Hydrometer Method
Abstract: 5.1 Accurate determination of the density, specific gravity, or API gravity of cutback asphalts is necessary for the conversion of measured volumes to volumes at the standard temperature of 15 °C or 60 °F. 5.2 Similarly, ... -
Standard Specification for Joints for Plastic Pressure Pipes Using Flexible Elastomeric Seals
Abstract: This specification covers the two types of joints, mechanical joint and push-on-joint, required for plastic pipe pressure systems with a wall thickness equal to or greater than that of SDR 64 intended for use in supply and ... -
Standard Test Method for Phenol Content of Cumene (Isopropylbenzene) or AMS (α–Methylstyrene)
Abstract: 4.1 This test method is useful in determining phenol in the range from 3 mg/kg to 50 mg/kg in commercially available cumene or AMS. 4.2 Phenol will inhibit certain reactions involving cumene or AMS. -
Standard Test Method for Spiral Flow of Low-Pressure Thermosetting Molding Compounds
Abstract: 4.1 The spiral flow of a thermosetting molding compound is a measure of the combined characteristics of fusion under pressure, melt viscosity, and gelation rate under specific conditions. 4.2 This test method is useful ... -
Standard Test Method for Monomethyl Ether of Hydroquinone in Colorless Monomeric Acrylate Esters and Acrylic Acid
Abstract: 4.1 Acrylic acid and its esters are normally inhibited with MEHQ only. This procedure presents a rapid and accurate method of determining the MEHQ content of fresh acrylic acid and acrylate esters in the absence of other ... -
Standard Test Method for Rubber Property—Hydrolytic Stability
Abstract: 4.1 Rubber and rubber products for certain applications must withstand the environmental effect of high humidity and resist the deterioration of physical properties under these conditions with time. This test method allows ... -
Standard Test Method for Tack of Pressure-Sensitive Adhesives by Rolling Ball
Abstract: 5.1 The rolling-ball tack test is fast, easy to run, and requires little investment in equipment and little operator training. This test is intended primarily for quality control use since it demonstrates good reproducibility ... -
Standard Specification for Alloy Structural Steel Plates
Abstract: This specification deals with alloy structural steel plates. Plate specimens addressed under this specification are available in four treatment conditions (as rolled or hot rolled; annealed; normalized; and normalized and ... -
Standard Practice for Flexibility Determination of Hot-Melt Adhesives by Mandrel Bend Test
Abstract: 5.1 The “Mandrel Bend” test is simple and fast. It requires little investment in equipment and little operator training. The prime purpose is to determine whether a hot-melt adhesive meets flexibility requirements. This ... -
Standard Test Method for Permanent Deformation of Elastomeric Yarns
Abstract: 5.1 Test Method D3106 for testing permanent deformation of elastomeric yarns is considered satisfactory for acceptance testing of commercial shipments when there is prior agreement as to the exact value of elongation to ... -
Standard Test Method for Softening Point of Pitches (Mettler Softening Point Method)
Abstract: 5.1 Pitch does not go through a solid-liquid phase change when heated, and therefore does not have a true melting point. As the temperature is raised pitch gradually softens or becomes less viscous. For this reason, the ... -
Standard Test Method for Thermal Insulation Performance of Distribution Packages
Abstract: 4.1 This test method is intended for use for evaluating the performance of thermal insulated packaging used for high-value, high-risk materials. This test method may also be used for any product that requires accurate ... -
Standard Test Methods for Structural Panels in Flexure
Abstract: 3.1 These methods give the flexural properties, principally strength and stiffness, of structural panels. These properties are of primary importance in most structural uses of panels whether in construction for floors, ... -
Standard Specification for Phthalocyanine Green Pigments
Abstract: This specification establishes the properties and requirements for chlorinated and chlorinated-brominated copper phthalocyanine green pigments in dry powder form, for use in paints, printing inks, and related products. The ... -
Standard Test Method for Flame Height, Time of Burning, and Loss of Mass of Rigid Thermoset Cellular Plastics in a Vertical Position
Abstract: 5.1 Tests made on rigid cellular materials in accordance with the conditions described by this test method can be of considerable value in comparing their burning characteristics. 5.2 This test method has been applied to ... -
