This SAE Recommended Practice provides general guidelines on the material selection, construction, and qualification of components and wiring systems used to construct nominal 12 VDC and/or 24 VDC electrical wiring systems for heavy-duty vehicles The guidelines are limited to nominal 12 VDC and/or...
This specification covers protective face guards designed to be attached to a pre-existing helmet for youth baseball. General requirements for protective face guards shall include mechanical strength, durability, flexibility, finish, padding, attachment system, and shall not cause skin irritation....
4.1 The Webster hardness gage is portable and therefore useful for in situ determination of the hardness of fabricated parts and individual test specimens for production control purposes. It is not as sensitive as Rockwell or Brinell hardness machines; see 10.2. 4.2 This test method should...
5.1 Tensile properties determined by this test method are of value for identifying and characterizing materials for control and specification purposes as well as for providing data for research and development studies. 5.2 This test method is intended for use in testing resin-compatible sized glass...
4.1 The use of this guide is voluntary and is intended for use as a procedures guide for selection and application of specific types of strain gages for high-temperature installations. No attempt is made to restrict the type of strain gage types or concepts to be chosen by the user....
4.1 Because the sample is prepared in a manner as it would be applied in the field, the test specimens may be considered representative of the application of a specified surfacing. Such methods include application by squeegees, rollers, trowels, notched trowels, and gage rakes. 4.2 These...
1.1 This practice covers a general procedure for using the Impulse Excitation Method (IEM) to facilitate natural frequency measurement and detection of defects and material variations in metallic and non-metallic parts. This test method is also known as Impulse Excitation Technique (IET), Acoustic...
1.1 This test method covers the determination of fracture toughness (KIc and optionally KIsi) of metallic materials under predominantly linear-elastic, plane-strain conditions using fatigue precracked specimens having a thickness of 1.6 mm (0.063 in.) or greater2 subjected to slowly, or in special...
5.1 This practice provides supplemental instructions for the use of Test Method D6484/D6484M to determine unnotched compressive strength data for material specifications, research and development, material design allowables, and quality assurance. Factors that influence compressive strengths and...
1.1 This test method determines the open-hole (notched) tensile strength of continuous fiber-reinforced ceramic matrix composite (CMC) test specimens with a single through-hole of defined diameter (either 6?mm or 3?mm). The open-hole tensile (OHT) test method determines the effect of the single...
1.1 This test method covers the measurement of tensile properties of geotextiles using a wide-width strip specimen tensile method. This test method is applicable to most geotextiles that include woven fabrics, nonwoven fabrics, layered fabrics, knit fabrics, and felts that are used for geotextile...
This practice provides a qualifying method to verify the proficiency and ability of coating applicators to attain the required quality for application of specified coatings to steel surfaces given the proper tools and equipment. The coating applicator shall be provided with information on the...
5.1 General: 5.1.1 This guide is intended to support PBF-LB process and parameter development, part acceptance criteria, and process control tests. 5.1.2 Flaws and Defects-Fabricating fully dense parts continues to be a challenge in AM as the process intrinsically introduces volumetric flaws into a...
1.1 These test methods cover the tension testing of wrought and cast aluminum- and magnesium-alloy products, with the exception of aluminum foil,2 and are derived from Test Methods E8M, which cover the tension testing of all metallic materials. Note 1: These metric test methods are the equivalents...
This specification covers aluminum in the form of foil and light gage sheet.
5.1 The methods described provide indirect measurement of the thickness of sections of materials not exceeding temperatures of 1200°F [650°C]. Measurements are made from one side of the object, without requiring access to the rear surface. 5.2 Ultrasonic thickness measurements are used extensively...
This practice covers procedures for the verification and classification of extensometer systems, but it is not intended to be a complete purchase specification. The practice is applicable only to instruments that indicate or record values that are proportional to changes in length corresponding to...
