3.1 The electrical conductivity of silica is related to both the adsorbed water and the hydroxyl groups on the surface of the precipitated, hydrated silica. Since the electrical conductivity of distilled or de-ionized water is very low, high electrical conductivity values are...
This SAE Aerospace Standard (AS) defines the requirements for a threadless, flexible, high conductive, self-bonding coupling assembly which, when installed on defined ferrules, provides a flexible connection for joining ducting and components in pressurized fluid systems. The assembled coupling is...
1.1 This test method covers the determination of the electrical conductivity of electrocoat baths or ultrafiltrate samples using commercially available equipment. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1...
1.1 This specification covers tin-coated copper-clad steel wire for electronic application. 1.2 Four classes of tin-coated copper-clad steel wire are covered as follows: 1.2.1 Class T30HS-Nominal 30?% conductivity, hard-drawn, 1.2.2 Class T30A-Nominal 30?% conductivity, annealed, 1.2...
1.1 This test method describes the determination of thermal conductivity of homogeneous, non-porous solid materials in the range of 0.10 W/(K·m) to 1.0?W/(K·m) by modulated temperature differential scanning calorimeter. This range includes many polymeric, glass, and ceramic materials....
1.1 These test methods cover the determination of the electrical conductivity and resistivity of water. The following test methods are included: Range Sections Test Method A-Field and Routine Laboratory 10 to 200?000 12 to 18 ?Measurement of Static (Non-Flowing) Samples ?μS/cm Test Method...
1.1 This specification covers bare concentric-lay-stran
This specification establishes the requirements for plates, sheets, strips, and rolled bars of copper-chromium-iron
5.1 Conductivity measurements are typically made on samples of moderate to high ionic strength where contamination of open samples in routine laboratory handling is negligible. Under those conditions, standard temperature compensation using coefficients of 1 to 3?% of reading per degree...
This specification covers seven grades of diesel fuel oils suitable for various types of diesel engines. These grades are: Grade No. 1-D S15; Grade No. 1-D S500; Grade No. 1-D S5000; Grade No. 2-D S15; Grade No. 2-D S500; Grade No. 2-D S5000; and Grade No. 4-D. The requirements specified for diesel...
1.1 These test methods cover the determination of specific resistance (resistivity) of liquid paints, solvents, and other fluids in the range of 0.6 to 2640 MO-cm. 1.2 Test Method A describes a procedure for making resistance tests with a commonly used paint application test assembly (Fig. 1 and...
4.1 The heat of hydration of a calcium aluminate-based castable is liberated over a short period of time (as compared to portland cement). This makes it easy to measure the heat profile using off-the-shelf thermocouple equipment. 4.2 The heat profile can be used to make inferences about the setting...
1.1 This test method covers the precise on-line determination of pH in water samples of conductivity lower than 100?μS/cm (see Table 1 and Table 2) over the pH range of 3 to 11 (see Fig. 1), under field operating conditions. pH measurements of water of low conductivity are problematic...
5.1 The ability of a fuel to dissipate charge that has been generated during pumping and filtering operations is controlled by its electrical conductivity, which depends upon its content of ion species. If the conductivity is sufficiently high, charges dissipate fast enough to prevent...
This specification covers lightweight aggregates intended for use in concrete not exposed to the weather, in which the prime consideration is the thermal insulating property of the resulting concrete. Two general types of lightweight aggregate are group I aggregates, which are prepared by expanding...
1.1 This standard practice describes standard procedures for using a conductive geotextile with electrical methods to locate leaks in exposed geomembranes and geomembranes covered with water or earth materials containing moisture. 1.2 This standard practice provides guidance for the use of...
This specification establishes the requirements for purchases of Grade UL 91 unleaded aviation gasoline under contract and is intended primarily for use by purchasing agencies. It does not cover any other gasolines satisfactory for reciprocating aviation engines. The unleaded aviation gasoline,...
4.1 This guide is intended to help analysts in the semiconductor industry. Examples of the usefulness of anion monitoring include: (1) determining when ion-exchange resin beds (in water-purification systems) need to be regenerated, and (2) ensuring that anion levels are low enough to allow the...
5.1 Accurate measurement of organic carbon in water at low and very low levels is of particular interest to the electronic, life sciences, and steam power generation industries. 5.2 Elevated levels of organics in raw water tend to degrade ion exchange resin capacity. Elevated levels of organics in...
