Abstract: This specification covers hot- and cold-worked precipitation hardenable cobalt-containing alloys (UNS R30155 and UNS R30816) rod, bar, forgings, and forging stock for high temperature service. The material shall conform ... -
Standard Test Method for Glazing and Glazing Systems Subject to Airblast Loadings
Abstract: 5.1 This test method provides a structured procedure to establish the hazard rating of glazing, glazing systems, and glazing retrofit systems subjected to an airblast loading. Knowing the hazard rating provides the ability ... -
Standard Guide for Techniques in Land Search
Abstract: 5.1 Lost persons are at risk of injury or death from extended periods of isolation, either mental, physical, or both. Their inability to solve immediate problems requires that search and rescue (SAR) personnel use the most ... -
Standard Test Methods for Detention Hollow Metal Vision Systems
Abstract: 4.1 A major concern for corrections administration officials is the resistance of security barriers used in detention/correctional facilities to certain types of physical attack that it is reasonable to expect in the field. ... -
Standard Specification for Composition of Anorganic Bone for Surgical Implants
Abstract: This specification covers material requirements for chemical composition of anorganic xenogeneic or allogeneic bone (apatite) intended for surgical implants. This specification specifically excludes synthetic hydroxylapatite, ... -
Standard Test Methods for Detention Locks for Swinging Doors
Abstract: 4.1 A major concern for detention and correctional administrative officials is the reliable operation of locks used in their facilities. These test methods aid in assigning a level of physical security and performance to ... -
Standard Test Method for Measuring Heat Stability of Resilient Flooring by Color Change
Abstract: 3.1 Resilient floor covering is made by fusing polymer materials under heat or pressure, or both, in various manufacturing and decorating processes. The polymer material may be compounded with plasticizers, stabilizers, ... -
Standard Specification for Coextruded Composite Pipe
Abstract: This specification covers coextruded composite pipe, produced by a coextrusion die system, in which the concentric layers are formed and combined before exiting the die. Coextruded composite pipe conforming to the requirements ... -
Standard Practice for Chemical Protective Clothing Program
Abstract: 4.1 This practice presents those elements that constitute a chemical protective clothing (CPC) program and conditions to be used in establishing a program for the selection and use of CPC. Adherence to this practice requires ... -
Standard Practice for Identifying Tire Tread Surface Irregular Wear Patterns Resulting from Tire Use
Abstract: 3.1 This practice fulfills the need for a standardized system for identifying and describing the tread pattern features of tires that are characteristic of intermediate states of treadwear short of total wear out. This ... -
Standard Specification for Precipitation-Hardening and Cold Worked Nickel Alloy Bars, Forgings, and Forging Stock for Moderate or High Temperature Service
Abstract: This specification covers hot- and cold-worked precipitation-hardenable nickel alloy rod, bar, forgings, and forging stock for high-temperature service. Chemical analysis shall be performed on the alloy and shall conform ... -
Standard Test Method for Resistance of Chemical Protective Clothing Materials to Liquid Permeation—Permeation Cup Method
Abstract: 5.1 This test method establishes a standard procedure for rapidly (in 1 h or less) determining the chemical resistance of specimens of protective clothing materials. This test method can be used to rank materials as to ... -
Standard Practice for Installation Acceptance of Plastic Non-pressure Sewer Lines Using Low-Pressure Air
Abstract: 4.1 This low-pressure air testing practice detects damaged piping or improper jointing by measuring the rate at which air under pressure escapes from an isolated section of sewer. 4.2 The rate of air loss indicates the ... -
Standard Specification for Ovens, Microwave, Electric
Abstract: This specification covers commercial microwave ovens. These ovens use ultrahigh frequency electromagnetic radiation in the approved industrial, scientific, and medical bands to defrost, heat, and cook food. The microwave ... -
