🔍 Scope and Significance ASTM D3925-02 (Reapproved 2022) establishes a standard practice for sampling liquid paints and related pigmented coatings. The practice covers methods for taking representative samples from containers of any type, ensuring that these samples are convenient and…
📖 Scope and Definitions This standard test method, designated ASTM D3921-96 (Reapproved 2011), is under the jurisdiction of ASTM Committee D19 on Water and has been approved for use by agencies of the Department of Defense. It provides a procedure…
ASTM D3923-23 establishes standard practices for detecting integrity breaches in reverse osmosis (RO) and nanofiltration (NF) devices. These practices are critical for identifying failures where there is a direct communication between the feed or concentrate and the permeate stream, which…
📐 Scope and Test Method Summary This test method covers the determination of dissolved and total recoverable strontium in water and wastewater by atomic absorption spectroscopy. The method is applicable in the range from 0.1 to 1 mg/L of strontium.…
📘 Surface and Cure Terminology This section defines terms related to surface imperfections and cure conditions in pultruded products. Barcol hardness is measured using a Barber Colman impresser, providing a relative measure of cure (Note 2 states values can differ…
ASTM D3919-15 establishes the standard practice for the quantitative determination of trace elements in water, wastewater, and various aqueous matrices using graphite furnace atomic absorption spectrophotometry (GFAAS). This technique is specifically designed for analytes present at concentration levels below the…
📐 Specimen Configuration and Testing Scope ASTM D3916-22 is the definitive standard for determining the tensile properties of pultruded glass-fiber-reinforced thermosetting plastic rods. It is specifically applicable to diameters ranging from 2.03 mm (0.08 in.) to 12.7 mm (0.5 in.),…
📐 Scope and Applicable Terminology ASTM D3917-23 defines production tolerances for standard rods, bars, shapes, and flat sheet pultruded from thermosetting glass-reinforced plastics. This specification, originally approved in 1980 and revised in 2023, provides a clear framework for evaluating profile…
ASTM D3914 – 02 (Reapproved 2016) provides a standardized method for determining the in-plane shear strength of pultruded, glass-fiber-reinforced thermosetting plastic rods. This test method is critical for assessing the reinforcement-to-resin bond quality in composites utilized across various structural applications.…
