Scope: The ASTM D2918 standard test method is used to determine the durability of adhesive junctions in T-peel-type specimens. This test method can be utilized as an accelerated screening test for determining adhesive joint durability. It can be used to assess the durability of adhesive joints exposed to the elements or to the circumstances that...
Scope: The ASTM D1184 test method is a standard test method for determining the flexural strength of adhesive bonded laminated assemblies when subjected to flexural stresses with standard form specimens and under defined pretreatment, temperature, relative humidity, and testing methodology conditions. Rather than reducing shear stress to a minimum, the test specimen and testing technique...
Scope: The ASTM D1002 is a standard test method for apparent shear strength of single-lap-joint adhesively bonded metal specimens by tension loading (Metal-to-Metal). This is largely a comparison test process. It can, however, be used as a discriminator to determine differences in adherend surface preparation conditions and adhesive environmental endurance. The test method has been...
Scope: The ASTM D2557 test technique is used for determining the comparative shear strength of adhesives for bonding metals when tested on a standard specimen and under specified preparation and testing conditions at extreme subzero temperatures. This test procedure is performed in the temperature range of -267.8°C (-450°F) to -55°C (-67°F). For homogeneous sets of...
Scope: The ASTM D2295 test technique is used to determine the comparative shear strengths of adhesives for bonding metals when they are tested on a standard specimen and under certain preparation and testing conditions at elevated temperatures. The ability to compare adhesive bond strength at increasing temperatures enables a better selection of adhesives that must...
Scope: When tested on a standard specimen and exposed to a specific temperature and tensile stress in a spring-loaded testing apparatus, the ASTM D2294 test technique covers the assessment of the creep properties of adhesives for bonding metals. This test method is valuable for comparing adhesive creep properties in research and development, especially when those...
Scope: When evaluated on a standard specimen and exposed to particular parameters of temperature and compressive stress in a spring-loaded testing apparatus, the ASTM D2293 test technique includes the assessment of the creep properties of adhesives for bonding metals. This test method is valuable for comparing adhesive creep properties in research and development, especially when...
Scope: The ASTM D2095 test technique specifies the use of bar-and rod-shaped butt-joined specimens to determine the relative tensile strength of adhesives. This test method can be used to evaluate adhesives using a variety of adherend materials in similar or distinct combinations. Specification acceptance, service evaluation, manufacturing control, research, and development all may benefit from...
Scope: The T-peel test (ASTM D1876) determines how much force is needed to gradually separate two bound, flexible adherents. Peel tests intended for flexible adhesives are designed to measure resistance to highly localized stresses. A peel test also measures a material’s adhesive strength of the adhesive bonding strength between two materials. The T-peel test is...
Scope: ASTM D1781 is a standard test method for determining adhesive bond peel resistance on items with a flexible adherend and a rigid adherend surface. By removing the sandwich assembly’s face, this standard can also be used to examine the structure and core of a sandwich. The purpose is to determine how much torque is...
Scope: The ASTM D1304 is a standard test method for adhesives relative to their use as electrical insulation and cover procedures for testing adhesives in liquid, highly viscous, solid, or set states. As per the ASTM D1304 method, the electrically insulated adhesives have a wide range of applications due to their good adherence to a...
Scope: The nonvolatile content of aqueous adhesives such as dextrin, starch, casein, and animal gelatin is determined using the ASTM D1489 test technique. Tube winding, laminating, case and carton sealing, packing, bottle labelling, flat gumming, envelope sealing, and gummed tape manufacturing are just a few of the applications for aqueous adhesives non-volatile components. For adhesive...
Scope: The blocking point of potentially adhesive material is determined using the ASTM D1146 test procedure. Because some potentially adhesive compounds are both thermoplastic and hygroscopic, this test method allows for assessing both thermoplastic and hygroscopic blocking on the same material. Because certain criteria are more stringent than others, ASTM D1146 recognizes and defines two...
Scope: The ASTM D1084 test method is used to determine adhesive viscosity. The adhesive’s fluid flow is also taken into account in order to suit the machine’s requirements. Viscosity is significant during the coating step because uncured adhesives react differently when “ran” across a surface. Adhesive makers usually provide the viscosity and solid content to...
Scope: The ASTM D4883 test method employs a modern ultrasonic wave propagation-based technique for determining the density of polyethylenes. For the identification and characterization of polyethylene, density measurements are quite useful. It’s typically used as a way to track physical changes in a sample or as a measure of sample uniformity. It is a critical...
