ASTM standards strength properties testing

A variety of tests are available for determining film quality. Many are based on ASTM standards. For example, tests for permeation of oxygen, water vapor, or other substances may be carried out, and will be discussed in Chapter 14. Tests for impact strength, tensile strength, tear strength, and other mechanical properties are important for many applications. Tests particularly related to quality control in the film production process include those that relate in some fashion to the appearance of the film.

When water is used as the immersion liquid, the test is essentially the ASTM Standard Test Method (D570) for Water Absorption of Plastics.( ) Determinations of the relative rate of water absorption are important in evaluating the effects of moisture exposure on such properties as mechanical strength, electrical resistivity, dielectric... 

The Standard Test Method for Strength Properties of Tissue Adhesive in T-Peel by Tension Loading, ASTM F 2256-03, was not employed for testing barrier dressings only porcine tissue was available in 15 cm strips that possessed thick hair on the epidermis side and a thick fat layer on the underside that was not conducive to testing. Removal of the fat layer to isolate the dermis will be necessary before testing by the T-Peel method.

Most mechanical properties reported in the United States are done according to standards described by the American Society of Testing and Materials (ASTM). The standard method for testing small, clear specimens of timber (ASTM D143) calls for the test to be conducted at 65% RH. Control specimens have a moisture content of approximately 9% (Table 3), whereas specimens reacted with acetic anhydride or formaldehyde have a moisture content of only about 4% and specimens reacted with butylene oxide 6%. This means that the standard test is run on specimens of different moisture contents. Because of the great effect of moisture content on mechanical properties (Table 1), it is misleading or even invalid, to compare strength properties of control and modified wood since they were tested at different moisture levels.

Since most silicone adhesives and sealants are elastomeric in nature, their physical property testing often parallels classical rubber testing approaches. Common tests include durometer, tensile strength, elongation, and modulus. Several methods are available for the measurement of rubber properties, but the most commonly used are the American Society for Testing and Materials (ASTM) D-412, Test Method for Rubber Properties in Tension, and the ASTM C-661, Standard Test for Indentation Hardness of Elastomeric-Type Sealants by Means of a Durometer. These properties vary widely with the product... 

Flexural modulus is a measure of the strength of adhesives. Modulus data are most often used in stress analysis (one-dimensional or as an input to 3D-modeling). In addition to flexural modulus, elongation-at-break is also recorded. The standard test method is ASTM D790, Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials. Two methods are specified. The first uses a three-point bending test two supports hold the part and a load is applied with a single point to induce...
