1.1 This test method determines the curved beam strength of a continuous fiber-reinforced composite material using a 90° curved beam specimen (Fig. 1). The curved beam consists of two straight legs connected by a 90° bend with a 6.4-mm inner radius. An out-of-plane (through-the-thickness) tensile stress is produced in the curved region of the specimen […]

1.1 These test methods cover procedures to determine the total mercury content in a sample of coal or coal combustion residue. 1.2 The values stated in SI units are regarded as the standard.

1.1 The specifheation covers a two part flowable space grade room temperature vulcanizing (RTV) silicone rubber adhesive or compound. The material is speifially designed for appli-cations requiring extreme low temperature, low oulgassing and minimal volatile condensibles under extreme operating condi-tions. The RTV silicone rubber should be suitable for with-standing environmental exposure to temperatures from -115

1.1 This test method covers the analysis of tannery liquors made up from vegetable tanning materials. 1.2 The values stated in SI units are to be regarded as the standard.

1.1 This test method covers determining the sugars present in vegetable tanning materials. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.1 This practice covers extracting the tannin from raw and spent materials. The water extract obtained by this method is used to determine the tannin content of the original material.Analysis for total solids, soluble solids, and soluble non-tannins of the water extract from a material provides the information necessary to calculate the extractable tannin con-tent

1.1 This test method is intended for use in determining the moisture content in raw and spent materials that are extracted for tannin analysis. The moisture content of the sample is operationally defined to be equal to the weight loss expericnced as a result of the evaporation which occurs in the drying oven. 1.2 The

1.1 This test method is intended for use in determining the quantity of soluble non-tannins and tannin in solutions of tannin extracts, water extracts of vegetable tanning materials, or tanning liquors. The method is applicable to the analysis of liquid, solid, pasty, and powdered extracts and to extracts of raw or spent materials.
