📐 Scope and Applicability of D4035‑22 ASTM D4035‑22 establishes the standard performance specification for knitted necktie and scarf fabrics composed of any textile fiber or mixture of textile fibers. The requirements apply to both the length (warp) and width (fill)…
The ASTM D4032-08 (Reapproved 2016) standard specifies the method for determining the stiffness of fabrics using the circular bend procedure. It is generally applicable to woven, knitted, and nonwoven textiles of any fiber content. The test principle involves a plunger…
This test method, designated D4033-92, provides a standardized procedure for measuring resistance to yarn slippage in upholstery fabrics under dynamic fatigue conditions. It evaluates three primary seam constructions commonly used in upholstery: warp sewn to warp (wale to wale), filling…
This specification provides requirements for continuous glass filament sewing thread and continuous filament cord, both untreated and neoprene treated. It assists users by designating typical industry products and establishes standards for construction, testing, and classification. 📐 Scope and Designation of…
The ASTM D4031-07 (Reapproved 2018) standard provides a standardized methodology for measuring the bulk properties of textured yarns. By evaluating the change in length of a tensioned skein subjected to specific environmental and loading conditions, this test method quantifies critical…
ASTM D4028/D4028M-13 (Reapproved 2021) is the standard specification for solar screening woven from vinyl-coated fiber glass yarn. It establishes requirements for screening designed to reduce solar heat gain while providing outward visibility and interior light, with insect-restraining capabilities equivalent to…
ASTM D4029/D4029M-23 specifies the requirements for finished woven glass fabrics made from “E” electrical glass fiber yarns, intended for use as reinforcing materials in laminated plastics for structural applications. This standard covers terminology, general requirements, and physical properties, and it…
This test method, designated D4027 −98 (Reapproved 2019), covers the determination of shear properties of structural adhesives using a modified-rail test configuration. Developed under the jurisdiction of ASTM Committee D14 on Adhesives, it is designed to provide accurate measurements of…
📋 Scope and Key Requirements This practice, designated as D4025-18, specifies the manner in which results of examination and analysis of deposits formed from water for subsurface injection are to be reported. It covers inorganic, organic, and biological constituents, differing…
📐 Scope and Principle This test method, designated ASTM D4026-06 (Reapproved 2021), covers the determination of residual styrene monomer in styrene-butadiene (SBR) latex. The procedure is based on the direct injection of a diluted latex sample into a gas chromatograph.…
