5.1 This test method is intended for testing dry and wet abrasion resistance of manufactured fiber yarns. This test method is useful for ropes intended for use in the marine environment and for knitted hoses for various applications. The test method has been used with yarns having...
1.1 These test methods cover the preparation and tensile testing of resin-impregnated and consolidated test specimens made from continuous filament carbon and graphite yarns, rovings, and tows to determine their tensile properties. 1.2 These test methods also cover the determination of the...
1.1 This test method covers accelerated testing for tensile creep, and tensile creep-rupture properties using the Stepped Isothermal Method (SIM). 1.2 The test method is focused on geosynthetic reinforcement materials such as yarns, ribs of geogrids, or narrow geotextile specimens. 1.3 The...
This specification covers finished fabrics woven from "E" electrical glass fiber yarns that are intended as a reinforcing material in laminated plastics for structural use. This specification can also be applied to fabrics made of other glass types. This specification permits the application...
5.1 This test method is considered satisfactory for acceptance testing of commercial shipments since current estimates of between-laboratory precision are acceptable, and this test method is used extensively in the trade for acceptance testing. 5.1.1 If there are differences of practical...
This specification covers the requirements for continuous fiber and staple fiber glass strands, including single, plied and multiple wound. It also covers textured glass fiber yarns. It is one of a series to provide a substitute for Military Specifications: MIL-Y-1140 Yarn, Cord,...
1.1 This test method covers the determination of the comparative tensile properties of glass fiber strands, yarns, and rovings in the form of impregnated rod test specimens when tested under defined conditions of pretreatment, temperature, humidity, and tension testing machine speed. This...
1.1 This specification primarily covers glass fabrics woven from "E" electrical continuous glass fiber rovings that are intended primarily as a reinforcing material in laminated plastics for structural use. 1.2 This specification specifies the terminology, definitions, general requirements, and...
5.1 This index test method is to be used to determine the strength of an individual junction in a geogrid product. The test is performed in isolation, while in service the junction is typically confined. Thus the results from this test method are not anticipated to be related to design performance....
This specification covers the requirements for continuous glass filament sewing thread and untreated and neoprene treated, continuous filament cord; intended to assist ultimate users by designing the types of these products that are typical in the industry. The fiber shall be electrical grade, free...
1.1 This test method covers the measurement of extension force developed while drawing a partially oriented filament yarn between pairs of draw rolls of different surface speeds. 1.2 Extension force provides an estimate of the yarn orientation. 1.3 This test method applies to...
1.1 This test method covers the determination of the yarn number of all types of cotton, woolen, worsted, and man-made fiber yarns taken from packages; or from any textile fabrics in which the yarns are intact and can be removed in measurable lengths. The test method is not...
5.1 The trapezoid tear method is a test that produces tension along a reasonably defined course such that the tear propagates across the width of the specimen. The trapezoid tearing strength for woven fabrics is determined primarily by the properties of the yarns that are gripped in the...
1.1 This specification covers prefabricated modified bituminous sheet materials reinforced with polyester fabric, with or without granules, that use atactic polypropylene (APP) as the primary modifier and are intended for use in the fabrication of multiple ply roofing and waterproofing membranes....
This specification covers the manufacture and requirements of Type II heavy-duty asphalt-impregnated and coated glass-fiber venting base sheet with mineral surfacing on the top side and coarse mineral granules on the bottom side for use as the first ply of a roofing membrane. The mat shall be a...
1.1 This practice describes a procedure for the division of shipments of yarn into test lots and the sampling of such lots for testing. 1.1.1 This practice can be used for lot sample testing of yarns for both pre-fabric production and post-fabric production. 1.2 This practice is...
5.1 This test method is considered satisfactory for acceptance testing of commercial shipments because it has been used extensively in the trade for that purpose. 5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative test...
1.1 These test methods cover the tensile testing of para-aramid flat yarns. The methods include testing procedure only and include no specifications or tolerances. 1.2 This standard includes the following test methods: Section Linear Density 10 Force at Specified Elongation (FASE) 11 Modulus...
3.1 Terminology D3888 was originally developed as a terminology standard for rotor spinning when it evolved as a new yarn spinning technology in the 1980s. Ring spinning production had been the traditional spinning since the early 1800s when hand spinning became mechanized. Rotor spinning...
1.1 This test method covers preparation and procedures to measure the thermal shrinkage force of yarns and cords in air. 1.2 This test method is applicable to measurement of the thermal shrinkage force of yarns and cords whose shrinkage force at 180 ± 2?°C (355 ± 4?°F) in air does not...
