5.1 In general, these procedures are more suitable for testing woven fabrics than knit fabrics. 5.2 Both test options in this test method are considered satisfactory for acceptance testing of commercial shipments since current estimates of between-laboratory precision are acceptable and the method...
1.1 This test method covers the measurement of the transparency of plastic sheeting in terms of regular transmittance (Tr). Although generally applicable to any translucent or transparent material, it is principally intended for use with nominally clear and colorless thin sheeting. 1...
5.1 These measurements give semiquantitative estimates for the gas transmission of single pure gases through film and sheeting. Correlation of measured values with any given use, such as packaged contents protection, must be determined by experience. The gas transmission rate is affected by...
This specification covers all forms of fiber-reinforced concrete that are delivered to a purchaser with the ingredients uniformly mixed. This specification may also apply to fiber-reinforced concrete intended for shotcreting by the dry-mix process when sampling and testing is possible at the point...
1.1 This test method covers a laboratory procedure for determining the no-pick-up time of pavement markings. The method uses a wheel consisting of a metal cylinder with rubber O-rings. The wheel is rolled down a ramp over a freshly applied pavement marking film repeatedly until there is no...
4.1 The extent of cracking or pitting of bituminous films is a measure of the extent of deterioration due to weathering. Failure due to cracking is more accurately determined electrically than visually. 4.2 Failure determined by this test method will depend not only on the characteristics of...
1.1 This practice covers a procedure for the preparation of accelerated and outdoor weathering test panels of bituminous coatings. It is considered suitable for the preparation of film thicknesses in the range from 0.25 to 2.54 mm [0.010 to 0.100?in.]. 1.2 The values stated in either SI...
5.1 This test method is applicable to the measurement of airborne asbestos in a wide range of ambient air situations and for detailed evaluation of any atmosphere for asbestos structures. Most fibers in ambient atmospheres are not asbestos, and therefore, there is a requirement for fibers to be...
This specification covers a group of common requirements that, unless covered by the individual product specification in another ASTM document, applies to steel forgings for general use. Materials shall be produced primarily by either electric-furnace, basic oxygen, vacuum-induction (VIM),...
1.1 These test methods cover procedures for sampling and testing mastics and coatings for use as weather and vapor retarder finishes on thermal insulations and for other accessory use. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are...
4.1 Purpose-Practices to be employed for the radiographic examination of materials and components with neutrons using digital neutron detectors are outlined herein. They are intended as a guide for the assessment of a digital neutron radiograph's characteristics. For information on neutron...
1.1 This test method covers the determination of the boiling point distribution and cut point intervals of crude oils and residues by using high temperature gas chromatography. The amount of residue (or sample recovery) is determined using an external standard. 1.2 This test method extends the...
1.1 This guide provides advice for conducting experiments to investigate the effects of helium on the properties of metals where the technique for introducing the helium differs in some way from the actual mechanism of introduction of helium in service. Techniques considered for introducing helium...
3.1 In production of paints, smoothness of the paint film is of paramount importance. Agglomerates or coarse particles larger than 45 μm are difficult to disperse and may prevent obtaining a smooth film. These test methods are a valuable quality control test for grading raw...
1.1 This test method covers the determinations of dry and wet bulk density, water absorption, and apparent porosity of thin sections of glass-fiber reinforced concrete. Note 1: This test method does not involve a determination of absolute specific gravity. Therefore, such pore space as may...
4.1 PFAS are widely used in commercial and industrial applications worldwide (see Fig. 1). PFAS are of concern due to their documented persistence and their studied impacts on human health and the environmental. While there is no comprehensive source of information on the many individual PFAS...
5.1 Materials such as engineered thermoplastic films are often used for flexible barrier packaging. However, handling and transportation can cause abrasion to the packaging film and possibly compromise the integrity of the contents (for example, sterility of a medical device)....
4.1 Vickers and Knoop hardness tests have been found to be very useful for materials evaluation, quality control of manufacturing processes and research and development efforts. Hardness, although empirical in nature, can be correlated to tensile strength for many metals, and is an indicator...
4.1 This test method is the procedure of choice for determining volatile content of sheet-fed and coldset web offset inks. This information is useful to the ink manufacturer and user and to environmental interests as part of the determination of the mass of volatile organic compounds emitted from...
6.1 Thermal degradation is often a major factor affecting the life of insulating materials and the equipment in which they are used. The temperature index provides a means for comparing the thermal capability of different materials in respect to the degradation of a selected property...
