ASTM D1621 Compressive Properties of Rigid Cellular Plastics
ASTM D1621 test method provides details about the rigid cellular materials by determining their compressive properties such as strain, stress, yield point, strength, displacement, deformation, stress-strain diagram, and modulus of elasticity. This method is mainly used for expanded plastics. The final results of this test method are expressed in SI units.
Scope:
The ASTM D1621 test method determines the compressive properties of rigid cellular plastics and specifies their behavior. The help of a load-deformation curve determines stress and modulus of elasticity. Yield point, strain, deformation, displacement, and gauge length are also measured. The test method provides data for research and aids in development and quality control, along with specifying the applications of these materials. In this way, this test method defines the standard for preparing and testing rigid cellular materials, especially plastics.
Procedure:
The apparatus used in ASTM D1621 consists of a testing machine, load measurement system, compression platens, displacement measurement system, and direct compression platen displacement system. A micrometer dial gauge is used to measure the specimen size. Then the sample is carefully aligned between the compression platens. The displacement, thickness, yield point, and deformation are detected by compressing the specimen. All these properties help define the applications of rigid cellular materials, especially plastics.
Specimen size:
As per ASTM D1621, the test specimen is square or circular with a minimum and maximum area of 25.8 cm.sq and 232 cm.sq respectively. The minimum height is 25.4 mm, and the full size should not exceed the width or diameter of the specimen.
Data:
In ASTM D1621, the apparent modulus (Ec ) can be calculated as:
Ec ꞊ WH/AD
Where (W=load, H= height, A=Area, D=Deformation)
Conclusion:
The ASTM D1621 test method determines the compressive properties of rigid cellular plastics and specifies their behavior.
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
