This test method covers the determination of ethylene oxide content in polyethoxylated nonionic surfactants. It can also be used for compounds containing propylene oxide or any compounds (glycols and glycol and polyglycol ethers and esters) which form unstable 1,2-diiodides on reaction with hydroiodic acid. The apparatus is comprised of the following: heat source which shall be an electric heater provided with a sliding rheostat or other means of heat control; flasks which shall be equipped with a standard ground-glass joint; condensers with standard joints; gas bubbler filled with dibutyl phthalate; buret; and pipet. The dual apparatus is designed to permit a sample and a blank to be run simultaneously. Reagent grade chemicals or reagents of sufficiently high purity including water, carbon dioxide or nitrogen, lubricant, dibutyl phthalate, glass beads, hydroiodic acid, hydrochloric acid, methanol, potassium dichromate, potassium iodide solution, sodium thiosulfate, and starch indicator solution shall be used in all tests. The ethylene oxide content shall be calculated from the amount of sodium thiosulfate solution required to titrate the sample and the blank, normality of sodium thiosulfate, and weight of the sample. Standard deviations for repeatability and reproducibility shall be estimated to determine the acceptability of the results.

This specification covers three types of nitrogen gas used as an electrical insulating material in electrical equipment: Type I, obtained from the air by liquefaction processes and dried; Type II, obtained from the air by liquefaction processes, deoxidized with hydrogen over a platinum catalyst, and dried; and Type III, obtained from the air by liquefaction processes and if necessary deoxidized by suitable means. Materials shall be tested and the individual grades shall conform to specified values of % volume of nitrogen and rare gases, hydrogen, and oxygen; and dew point.

This test method covers the determination of inorganic active oxygen in bleaching compounds such as perborates, percarbonates, and peroxides by titration of an acidified aqueous solution with a standard solution of potassium permanganate. Tests shall use reagent grade chemicals, reagent water, potassium permanganate standard solution, sodium oxalate, and sulfuric acid. Well mixed sample shall be titrated according to the procedure indicated in this standard method. Active oxygen weight percent shall be calculated using the given formula.

This specification covers particulate glass (cullet material) recovered from waste destined for disposal, smaller than 6 mm intended for reuse as a raw material in the manufacture of glass containers. Flint glass cullet is a particulate glass material that contains no more than 0.1 weight % Fe2O3, or 0.0015 weight % Cr2O3, as determined by chemical analysis. The color mix for amber, flint, green and other color glass cullet shall conform to the prescribed mix.

This specification covers metallic-coated carbon steel wire for the manufacture of chain-link fence fabric and marcelled tension wire. Three coating types, namely: Type I (aluminized), Type II (galvanized), and Type III (zinc-aluminum-mischmetal alloy-coated), and five coating classes, namely: Class 3, Class 4, Class 5, Class 60, and Class 100, are covered. This specification does not cover the wire for chain-link fence when the coating is to be applied after the weaving process. The steel rod from which the wire is to be drawn shall be manufactured by the open-hearth, electric-furnace, or basic-oxygen process. The wire shall be cold-drawn, then metallic-coated at finished size to produce the specified mechanical properties such as breaking strength. Type I and Type III coatings shall be produced by a hot-dip process and Type II coating by either a hot-dip or an electrolytic process. The ingot or pig aluminum to be used for Type I coating shall conform to the impurity limits specified for copper and iron. Requirements for coated wire diameter, coating weight, coating adherence, and methods of chemical analysis and breaking strength test are detailed.

This specification covers the requirements for an adhesive which is intended for use in bonding pre-fabricated acoustical materials to the inside walls and ceilings of rooms in buildings. This adhesive is required to maintain a specific tensile adhesion or bond strength for a long period of time under the temperature and moisture conditions likely to be encountered and to maintain sufficient plasticity to allow for movement of parts of the building as it ages. The adhesive shall be of uniform composition, shall be free from all ingredients that will affect its serviceability or have a deleterious effect on the acoustical material, shall not liberate toxic gases or fumes under normal conditions of use and application, nor shall it contain irritating substances. Tests shall be conducted to determine the following adhesive properties: surface adherence; wetting; tensile and adhesion strengths; volume shrinkage; cracking; and plasticity to permit indentation. The specimens shall also be subjected to migration or bleeding and storage tests.

This guide presents directions for the installation, use, and storage of full-size or nearly full-size movable soccer goals. It is expected that these guidelines can help prevent deaths and serious injuries resulting from soccer goal tipover. These guidelines are intended for use by parks and recreation personnel, school officials, sports equipment purchasers, parents, coaches, and any other members of the general public concerned with soccer goal safety. These guidelines are intended to address the risk of movable soccer goal tipover. In designing soccer goal, the following may be considered: use of a counterbalancing strategy by lengthening the over all depth of the goal to effectively place more mass further from the goal's front posts, selection of light materials for the goal's front posts and crossbar and provides much heavier materials for the rear ground bar and frame members, use of a heavy rear framework and folds flat when not in use, making the goal much less likely to tip over. Securing soccer goals may be done in several ways. The number and type of anchors to be used will depend on a number of factors, such as types of playing surface, soil type, soil moisture content, and total goal weight. These anchor types shall include: Auger-Style Stake which is helical in shape and is screwed into the ground, Peg- or Stake-Style Stake which varies in lengths and diameters, J-Hook-Shaped-Stake Style which varies in lengths and diameters and its curved-top portion is designed to fit over goal members to secure it to the ground, and All-Stakes styles in which a minimum of two stakes must be used for each goal. Sandbags or other counterweights could be an effective alternative to anchors on hard surfaces, such as artificial turf, where the surface cannot be penetrated by a conventional anchor, that is, an indoor practice facility. Also a semipermanent anchor type may be used which is usually comprised of two or more functional components. The main support requires a permanently secured base that is buried underground. One type of semipermanent anchor connects the underground base to the soccer goal by means of two tethers. Another design utilizes a buried anchor tube with a threaded opening at ground level. Net pegs may be tapered, metal or plastic stakes, or both, and should only be used to secure the net to the ground.
