📐 Scope and Referenced Test Methods The ASTM D1117-01 standard is a comprehensive guide covering the evaluation of nonwoven fabrics. It provides a structured framework for testing by referencing specific ASTM standard test methods. The guide was reinstated in 2001…
The ASTM D1118/D1118M standard (reapproved 2017) specifies a test method for the magnetic rating of asbestos fiber and asbestos textile products. This method is primarily used for testing asbestos insulating materials. The standard emphasizes that values in SI or inch-pound…
The ASTM D1110-21 standard outlines standardized test methods for determining the water solubility of wood. These methods are crucial for characterizing the presence of extraneous components in wood samples, which can impact properties like color, odor, and adhesive bonding. The…
📐 Test Method Overview This test method, designated as D1113-13, covers the determination of oven-dried, ash-free, alcohol extractive-free vegetable matter and other alkali-insoluble impurities in scoured wool. It is also applicable to related fibers such as goat hair, camel hair,…
The ASTM D1107-21 standard specifies a test method for determining the ethanol-toluene solubility of wood. This test measures the content of waxes, fats, resins, oils, tannins, and other soluble components that are not part of the wood’s polymeric structure. 📐…
🧪 Overview and Significance This test method, designated D1108-21, covers the determination of dichloromethane soluble content in wood, which serves as a measure of waxes, fats, resins, oils, and similar materials. The dichloromethane extractable content is influenced by seasoning or…
🔬 Scope and Significance of the Test ASTM D1109-21 covers the determination of the solubility of wood in a hot, dilute alkali solution. Specifically, a 1 % sodium hydroxide (NaOH) solution is used. The primary application of this test is…
The ASTM D1105-21 standard establishes a definitive method for removing extractives from wood samples prior to chemical analysis. This ensures that subsequent tests accurately reflect the structural polymer components (cellulose, hemicellulose, and lignin) of the wood rather than its soluble…
🔬 Scope and Principle of the Method ASTM D1106-21 defines the standard procedure for determining the acid-insoluble lignin content of wood, commonly referred to as the 72 % sulfuric acid method. Wood naturally contains approximately 20 to 30 % lignin,…
ASTM D1101 – 97a (Reapproved 2024) specifies accelerated test methods for measuring the resistance to delamination of adhesive joints in structural laminated wood products, also known as glulam, intended for exterior service. The test is designed to evaluate whether the…
