Standard Test Method for Determination of the Spectral Mismatch Parameter Between a Photovoltaic Device and a Photovoltaic Reference Cell
Abstract: 5.1 The calculated error in the photovoltaic device current determined from the spectral mismatch parameter can be used to determine if a measurement will be within specified limits before the actual measurement is performed. ... -
Standard Test Method for Electrical Performance of Photovoltaic Cells Using Reference Cells Under Simulated Sunlight
Abstract: 5.1 This test method provides a procedure for testing and reporting the electrical performance of photovoltaic cells. 5.2 The test results may be used for comparison of cells among a group of similar cells or to compare ... -
Standard Practice for Heat Flow Calibration of Differential Scanning Calorimeters
Abstract: 5.1 Differential scanning calorimetry is used to determine the heat or enthalpy of transition. For this information to be meaningful in an absolute sense, heat flow calibration of the apparatus or comparison of the resulting ... -
Standard Practice for Evaluation of Antimicrobial Agents as Preservatives for Invert Emulsion and Other Water Containing Hydraulic Fluids
Abstract: 5.1 This procedure is designed to determine the effectiveness of antimicrobial agents intended for microbial control in invert emulsions and other water containing hydraulic fluids. -
Standard Test Methods for Flow Rate of Metal Powders Using the Hall Flowmeter Funnel
Abstract: 5.1 The rate and uniformity of die cavity filling are related to flow properties, which thus influence production rates and uniformity of compacted parts. 5.2 The ability of a powder to flow is a function of interparticle ... -
Standard Guide for Investigating the Effects of Helium in Irradiated Metals
Abstract: 4.1 Helium is introduced into metals as a consequence of nuclear reactions, such as (n, α), or by the injection of helium into metals from the plasma in fusion reactors. The characterization of the effect of helium on the ... -
Standard Classification for Solar Simulators for Electrical Performance Testing of Photovoltaic Devices
Abstract: This specification provides the performance requirements and parameters used for classifying both pulsed and steady state solar simulators intended for indoor testing of photovoltaic devices (solar cells or modules), ... -
Standard Practice for Evaluation of Fungal Control Agents as Preservatives for Aqueous-Based Products Used in the Paper Industry
Abstract: 5.1 This practice should be used to determine if a fungal control agent is effective to preserve pigment suspensions, dye solutions, pulp slurries, starch solutions, polymers, sizing agents, latex emulsions, and other ... -
Standard Practice for Analysis and Interpretation of Light-Water Reactor Surveillance Neutron Exposure Results
Abstract: 3.1 The objectives of a reactor vessel surveillance program are twofold. The first requirement of the program is to monitor changes in the fracture toughness properties of ferritic materials in the reactor vessel beltline ... -
Standard Test Method for Determining Residual Stresses by the Hole-Drilling Strain-Gage Method
Abstract: 5.1 Summary: 5.1.1 Residual stresses are present in almost all materials. They can be created during the manufacture or life of the material. Residual stresses can be a significant factor in the failure of a material, ... -
Standard Guide for Sensor Set Design and Irradiation for Reactor Surveillance
Abstract: 4.1 In neutron dosimetry, a fission or non-fission dosimeter, or combination of dosimeters, can be used for determining a fluence rate, fluence, or neutron spectrum in nuclear reactors. Each dosimeter is sensitive to a ... -
Standard Test Method for Linear Thermal Expansion of Solid Materials by Thermomechanical Analysis
Abstract: 5.1 Coefficients of linear thermal expansion are used, for example, for design purposes and to determine if failure by thermal stress may occur when a solid body composed of two different materials is subjected to temperature ... -
Standard Test Method for Resistance to Attrition of Granular Carriers and Granular Pesticides
Abstract: 4.1 This procedure was designed principally with granular clay, corncob, nut shell, or sand carriers and granular pesticide products, but need not be limited to these materials. There may be more appropriate test methods ... -
Standard Test Methods for Determining Bulk Density of Granular Carriers and Granular Pesticides
Abstract: 3.1 These test methods were designed principally for clay, corncob, nut shell, paper-based or sand granular carriers, and granular pesticide products, but need not be limited to these materials. There may be more appropriate ... -
Standard Test Method for Measuring Reaction Rates by Radioactivation of Neptunium-237
Abstract: 5.1 Refer to Practice E261 for a general discussion of the determination of fast-neutron fluence rate with fission detectors. 5.2 237Np is available as metal foil, wire, or oxide powder. For further information, see Guide ... -
Standard Test Method for Critical Radiant Flux of Floor-Covering Systems Using a Radiant Heat Energy Source
Abstract: 5.1 This fire test response standard is designed to provide a basis for estimating one aspect of the fire exposure behavior of a floor-covering system installed in a building corridor. The test environment is intended to ... -
Standard Test Method for Apparent Density of Free-Flowing Metal Powders Using the Hall Flowmeter Funnel
Abstract: 5.1 This test method provides a guide for evaluation of an important physical characteristic of a powder known as the apparent density. The measured apparent density bears a relationship to the mass of powder that will ... -
Standard Test Methods for Testing Industrial Resistance Thermometers
Abstract: 4.1 These test methods provide uniform methods for testing industrial resistance thermometers so that a given tester may expect to obtain the same value of a test result from making successive measurements on the same test ... -
Standard Practice for Evaluation of Microbicides Used in Cooling Water Systems
Abstract: 5.1 This practice determines potentially effective microbicides for use in cooling water systems using cooling water and deposits/biofilm obtained from the field. The addition of deposits/biofilms addresses the need to ...
