5.1 The volume of a complex shaped PM part cannot be measured accurately using micrometers or calipers. Since density is mass per unit volume, a precise method for measuring the volume is needed. Archimedes' principle may be used to calculate the volume of water displaced by an immersed...
1.1 This test method covers the measurement of thickness of flexible packaging materials using contact micrometers. 1.2 The Precision and Bias statement for this test method was developed using both handheld and bench top micrometers with foot sizes ranging from 4.8?mm to 15.9?mm...
1.1 This test method covers the determination of several elements (including iron, nickel, sulfur, and vanadium) occurring in crude oils. 1.2 For analysis of any element using wavelengths below 190?nm, a vacuum or inert gas optical path is required. 1.3 Analysis for elements such as arsenic,...
3.1 The overall thickness or caliper of resilient flooring is a basic physical property. However, conventional means of measuring the thickness, such as a hand micrometer or regular dial micrometer, are not applicable for foam-layer products due to the error from compressing the foam....
This specification covers bare round copper-clad steel wire for electronic application. Four classes of copper-clad steel wire are covered as Class 30HS, 30A, 40HS, and 40A. The wire shall consist of a core of homogeneous open-hearth, electric-furnace, or basic-oxygen steel with a continuous outer...
4.1 The purpose of these test methods is to establish consensus test methods by which both manufacturers and end users may perform tests to establish the validity of the readings of their radiation thermometers. The test results can also serve as standard performance criteria for instrument...
This specification establishes the requirements for autocatalytic (electroless) nickel-phosphorus coatings applied from acidic aqueous solutions to metallic products for use in engineering functions operating at elevated temperatures. The coatings covered here are alloys of nickel and phosphorus...
1.1 This test method covers the determination of elements in biodiesel and biodiesel blends by microwave plasma atomic emission spectrometry (MP-AES). The specific elements within the scope of this method are calcium (Ca), magnesium (Mg), phosphorus (P), potassium (K), and sodium (Na). 1.2 This...
1.1 This test method covers the determination of the Differential Indentation Depth hardness of metallic materials by the Differential Indentation Depth hardness principle. This standard provides the requirements for Differential Indentation Depth hardness testing machines and the procedures for...
1.1 This test method may be used to determine the initial, fractional, filtration efficiency of household and commercial canister (tank-type), stick, hand-held, upright, and utility vacuum cleaner systems. 1.1.1 Water-filtration vacuum cleaners which do not utilize a replaceable dry media filter...
This Standard specifies micrometer for external measurements, bar-shaped micrometer for internal measurements, micrometer for span measurements of teeth, and micrometer head (hereafter referred to as micrometer, unless otherwise specified) equipped with analogue...
1.1 This test method was developed for ranking the high-stress abrasion resistance of cemented carbides, but it has been successfully used on ceramics, cermets, and metal matrix hardfacings with a hardness over 55 Rockwell hardness, C scale (HRC). The feature of this test method that discriminates...
This specification covers the standard general requirements for lead-coated and lead-alloy-coated, round, soft or annealed copper wire for electrical purposes. The base metal shall be made of copper while the coating material shall be a commercially pure lead or a lead alloy which consists of lead,...
This specification establishes the requirements for autocatalytic (electroless) nickel-phosphorus coatings applied from acidic aqueous solutions to metallic products for use in engineering functions operating at elevated temperatures. The coatings covered here are alloys of nickel and phosphorus...
4.1 This practice is useful as one method of controlling some electroplating solutions. It serves to indicate the presence of contamination or some other adverse condition. 4.2 Ductility measurements are of particular value when electroplated parts are to be subjected to moderate stress such as...
5.1 Silver may be used to treat consumer textile products to provide enhanced antimicrobial (fungi, bacteria, viruses) properties (3, 4). At any point in a textile product's lifecycle, there may be a need to measure the amount of silver present. This standard prescribes a test method based on...
4.1 This practice provides procedures commonly used for measuring the thickness of steel sheet products under the jurisdiction of ASTM Committees A01 and A05 and their subcommittees as designated by a purchaser in a purchase order or contract. 4.2 Thickness is a significant quality characteristic...
Purpose. This specification defines the procedures to be followed for the electrodeposited cadmium plating of fasteners, fastening systems and other related hardware primarily as a corrosion protective plating. Classification. The plating shall be of the following types and classes as specified....
This SAE International Aerospace Standard covers requirements for micrometer adjustable, feel impulse, torque wrenches. The torque wrench is used to apply a pre-set torque to threaded fasteners and other torque requirements.
1.1 This test method covers the determination of the relative permittivity (dielectric constant) and dissipation factor of solid dielectrics from 50 Hz to 10 MHz over a range of temperatures from -80 to 500 °C.2,3 Two procedures are included as follows: 1.1.1 Procedure A-Using Micrometer...
