Standard Practice for Periodic Inspection of Building Facades for Unsafe Conditions
Abstract: 4.1 Intent—This standard practice is intended to establish the minimum requirements for conducting periodic inspections of building facades to identify unsafe conditions that could cause harm to persons and property. It ... -
Standard Test Method for Instrumented Impact Testing of Metallic Materials
Abstract: 5.1 Instrumented impact testing provides an independent measurement of the absorbed energy associated with fracturing CVN or MCVN specimens for test machines equipped with a dial or optical encoder, or both. 5.2 Instrumented ... -
Standard Test Method for Determining the Drainage Efficiency of Exterior Insulation and Finish Systems (EIFS) Clad Wall Assemblies
Abstract: 5.1 This test method is a standard procedure for determining the drainage efficiency of an EIFS clad wall assembly. -
Standard Test Method for Paired Preference Test
Abstract: 5.1 The paired preference test determines whether or not there is a preference for one product over another product among a specific target population. Knowledge of consumer segments, brand loyalties, the range of product ... -
Standard Test Method for Impact Testing of Miniaturized Charpy V-Notch Specimens
Abstract: 5.1 There are cases where it is impractical or impossible to prepare standard CVN specimens. MCVN specimens are an alternative approach for characterizing notched specimen impact behavior. Typical applications include MCVN ... -
Standard Test Methods for Measurement of Electrical Performance and Spectral Response of Non-concentrator Multijunction Photovoltaic Cells and Modules
Abstract: 4.1 In a series-connected multijunction PV device, the incident total and spectral irradiance determines which component cell will generate the smallest photocurrent and thus limit the current through the entire series-connected ... -
Standard Specification for Nickel-Molybdenum Alloy Plate, Sheet, and Strip
Abstract: This specification covers plate, sheet, and strip of nickel-molybdenum alloys covering UNS N10001, N10665, N10675, N10629, and N10624 for use in general corrosive service. Product analysis shall be performed on the alloy ... -
Standard Test Method for Multiangle Color Measurement of Metal Flake Pigmented Materials
Abstract: 5.1 Instrumental Measurement Angles—This test method is designed to provide color data at specific measurement angles that can be utilized for quality control, color matching, and formulating in the characterization of ... -
Standard Practice for Application of Hose Stream
Abstract: 4.1 This practice is intended to standardize the apparatus used and the method or pattern of application of a standard hose stream to building elements as one part of the assessment and fire resistance of building elements. ... -
Standard Guide for Evaluating Non-Contacting Optical Strain Measurement Systems
Abstract: This guide assists potential users in understanding the issues related to the accuracy of non-contacting strain measurement systems and to provide a common framework for quantitative comparison of optical systems. The ... -
Standard Test Method for Directional Difference Test
Abstract: 5.1 The directional difference test determines with a given confidence level whether or not there is a perceivable difference in the intensity of a specified attribute between two samples, for example, when a change is ... -
Standard Test Method for Determining the Antimicrobial Activity of Antimicrobial Agents Under Dynamic Contact Conditions
Abstract: 5.1 Substrate–bonded, antimicrobial agents are not typically free to diffuse into their environment under normal conditions of use. This test method ensures good contact between the bacteria and the treated fiber, fabric, ... -
Standard Test Method for Same-Different Test
Abstract: 5.1 This overall difference test method is used when the test objective is to determine whether a sensory difference exists between two products. 5.2 The test is appropriate in situations where products have extreme ... -
Standard Test Method for Evaluating the Tensile-Adhesion Performance of an Exterior Insulation and Finish System (EIFS) or EIFS with Drainage
Abstract: 5.1 Maintaining adequate tensile adhesion of EIFS and EIFS with drainage components to each other and to the substrate is essential for long term performance of the system. 5.2 The tensile-adhesion properties obtained by ... -
Standard Test Method for Using a Rolling Inclinometer to Measure Longitudinal and Transverse Profiles of a Traveled Surface
Abstract: 5.1 This test method establishes procedures for collecting elevation and distance data of longitudinal and transverse profiles on a traveled surface. 5.2 Results of this test are used primarily to: 5.2.1 Evaluate the ... -
Standard Test Method for Compressibility of Metal Powders in Uniaxial Compaction
Abstract: 5.1 The compressibility value obtained by this test is a measure of a material characteristic of the powder. 5.2 The test method is useful in research and development projects, as a quality control test in the evaluation ... -
Standard Practice for Calibration of the Electron Binding-Energy Scale of an X-Ray Photoelectron Spectrometer
Abstract: 5.1 X-ray photoelectron spectroscopy is used extensively for the surface analysis of materials. Elements (with the exception of hydrogen and helium) are identified from comparisons of the binding energies determined from ... -
Standard Test Method for Determining Tensile Breaking Strength of Glass Fiber Reinforcing Mesh for Use in Exterior Insulation and Finish Systems (EIFS) and EIFS with Drainage Systems, after Exposure to a Sodium Hydroxide Solution
Abstract: 5.1 Glass fiber reinforcing meshes are used to strengthen EIFS and EIFS with drainage. The reinforcing meshes are embedded into base coats that contain portland cement, which potentially exposes the glass fibers in the ... -
