Standard Test Method for Spreading of Liquid Agricultural Spray Mixtures
Abstract: 5.1 This test method is intended to provide a rapid means of determining the relative ability of a liquid agricultural spray mixture to spread on a test substrate. 5.2 This test method was validated using Parafilm M3 as ... -
Standard Test Method for Volumetric and Mass Flow Rate Measurement in a Duct Using Tracer Gas Dilution
Abstract: 5.1 The method presented here is a field method that may be used to determine mass and volume flow rates in ducts where flow conditions may be irregular and nonuniform. The gas flowing in the duct is considered to be an ... -
Standard Test Method for Mass Scale Calibration of Thermogravimetric Analyzers
Abstract: 5.1 This test method calibrates or demonstrates conformity of thermogravimetric apparatus at ambient conditions. Most thermogravimetry analysis experiments are carried out under increasing temperature conditions or at ... -
Standard Guide on Metallographic Laboratory Safety
Abstract: 4.1 This guide is intended as a summary of safety practices in the metallography laboratory. It can be used as a training reference for those new to the field of metallography and as a refresher to those who are experienced. ... -
Standard Practice for Fabrication of the Neutron Radiographic Beam Purity Indicators
Abstract: 5.1 The BPI is designed to yield quantitative information concerning neutron beam and image system parameters that contribute to film exposure and, thereby, affect overall image quality. For proper measurements of film ... -
Standard Guide for Assessing Depressurization-Induced Backdrafting and Spillage from Vented Combustion Appliances
Abstract: 5.1 Although a number of different methods have been used to assess backdrafting and spillage (see NFPA 54/ANSI Z223.1, CAN/CGSB-51.71, and 1-4)6 a single well-accepted method is not yet available. At this point, different ... -
Standard Specification for Titanium Sponge
Abstract: This specification covers virgin titanium metal melting stock. This virgin metal is commonly designated as sponge titanium because it is most commonly porous and spongelike in texture, although metal produced electrolytically ... -
Standard Specification for Shelter, Electrical Equipment S-250/G
Abstract: This specification establishes the requirements and the corresponding test methods for one type of lightweight field and mobile shelter designed for transport by cargo truck, fixed or rotary winged aircraft, by rail, and ... -
Standard Test Method for Estimating the Approximate Residual Circumferential Stress in Straight Thin-walled Tubing
Abstract: 4.1 Residual stresses in tubing can be detrimental to its future mechanical performance. Such stresses can, for example, make the tubing more susceptible to stress corrosion cracking when exposed to certain environments. ... -
Standard Guide for Evaluating Data Acquisition Systems Used in Cyclic Fatigue and Fracture Mechanics Testing
Abstract: This guide covers how to understand and minimize the errors associated with data acquisition in fatigue and fracture mechanics testing equipment. This guide is not intended to be used instead of certified traceable calibration ... -
Standard Practice for Acoustic Emission Examination of Pressurized Containers Made of Fiberglass Reinforced Plastic with Balsa Wood Cores
Abstract: 4.1 This practice does not rely on absolute quantities of AE parameters. It relies on trends of cumulative AE counts that are measured during a specified sequence of loading cycles. This practice includes an example of ... -
Standard Test Method for Sensory Analysis—Triangle Test
Abstract: 5.1 The test method is effective for the following test objectives: 5.1.1 To determine if a perceptible difference results or if a perceptible difference does not result, for example, when a change is made in ingredients, ... -
Standard Test Methods for Determining Mechanical Integrity of Photovoltaic Modules
Abstract: 4.1 The useful life of photovoltaic modules may depend on their ability to withstand periodic exposure to high wind forces, cyclic loads induced by specific site conditions or shipment methods, high loads caused by accumulated ... -
Standard Practice for Efficacy of Slimicides for the Paper Industry—Bacterial and Fungal Slime
Abstract: 5.1 This practice is to be used to determine if a slime control agent has application in the paper industry for control of bacterial or fungal slime/biofilm. 5.2 This practice is run in acid, alkaline, or acid and alkaline ... -
Standard Specification for Laboratory Glass Volumetric Flasks, Special Use
Abstract: This specification covers the requirements for precision grade glass volumetric flasks for laboratories and specialty use. The products can be grouped into three styles according to size and shape. All products should be ... -
Standard Practice for Computed Tomographic (CT) Examination of Castings
Abstract: 4.1 CT may be performed on an object when it is in the as-cast, intermediate, final machined condition, or as a flaw or failure detection tool. A CT examination can be used as a design tool to improve wax forms and moldings, ... -
Standard Specification for Non-Reinforced Liquid Coating Encapsulation Products for Leaded Paint in Buildings
Abstract: This specification covers minimum material performance requirements and laboratory test procedures for nonreinforced liquid coating encapsulation products (single or multiple-coat systems) for leaded paint in buildings. ... -
