ASTM Standards Interpretation
🎯 Scope and Significance This test method, designated as D3082-15, covers the determination of boron in water and wastewaters using the curcumin colorimetric-extraction method. It is applicable for boron concentrations between 0.1 and 1.0 mg/L, and the range can be…
🔬 Scope and Overview of the Practice ASTM D3084-20, Standard Practice for Alpha-Particle Spectrometry of Water, provides the framework for obtaining well-resolved alpha-particle spectra from water samples, while addressing the common problems associated with identification and measurement. This practice is…
📋 Test Overview and Conditions This test method, designated D3079‑94 (Reapproved 2009)´1, determines the water vapor transmission rate (WVTR) of flexible heat‑sealed packages intended for dry products. The standard quantifies the amount of water vapor that permeates through a package…
📐 Scope and Specimen Requirements This test method, designated D3080/D3080M−23, covers the determination of the consolidated drained shear strength of a single soil specimen under direct shear boundary conditions. The specimen is deformed at a controlled rate on or near…
ASTM D3078-02 (Reapproved 2021), formally designated as the “Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission,” outlines a qualitative procedure for detecting gross leaks in flexible packages containing a headspace gas. Issued under the jurisdiction…
📐 Overview and Scope of ASTM D3075-94 The ASTM D3075-94 standard, originally developed by the Chemical Specialties Manufacturers Association (CSMA) and under the jurisdiction of Committee D10 on Packaging, provides a definitive test method for determining the overrun of food…
🔍 Scope and Overview of D3076-18 ASTM D3076-18 establishes standardized practices for evaluating effective crimping on outside crimped valves of aerosol containers. It provides quality assurance frameworks adaptable to the wide variety of container and valve assemblies available in the…
🧪 Test Apparatus and Sample Conditioning The accuracy and reproducibility of drop testing per ASTM D3071‑94 depend heavily on a standardized apparatus and strict sample conditioning. The drop surface consists of a 12 × 12‑in. (305 × 305‑mm) steel plate, 0.25 in. (6.4 mm) thick, embedded…
🧪 Overview and Significance of ASTM D3074‑94 The ASTM D3074‑94 standard, Standard Test Methods for Pressure in Metal Aerosol Containers, outlines two definitive procedures for measuring the internal pressure of aerosol containers. The classification and specification of containers by the…
This article covers the ASTM D3069‑94 (Reapproved 2013) standard, which provides a reliable method for measuring the delivery rate of aerosol products. The test is essential for evaluating valve performance and is often a prerequisite for both biological and storage testing.…
🧪 Apparatus and Test Setup This practice specifies a rapid pressure determination setup utilizing a stainless steel pressure gage with a range of 0 to 160 psi (0 to 1.1 MPa) and preferably one-number graduations. The gage must be attached…
🧪 Formulation Components and Ingredients This terminology standard clearly defines the components of an aerosol formulation. The active ingredient is the component producing the product’s specific effect, while an inert (inactive) ingredient does not contribute to this effect. The standard…
