Ferritic and martensitic steel shall be cooled after pouring to provide complete transformation of austenite prior to heat treatment to enhance mechanical properties. Chemical, heat, and product analyses shall be performed and the chemical composition thus determined shall conform to the prescribed values in carbon, manganese, silicon, phosphorus, sulfur, nickel, chromium, molybdenum, vanadium, tungsten, copper, and aluminum. Tensile testing shall be done on the castings and shall meet the required yield and tensile strength, elongation, and reduction of area. Each casting shall also be tested after machining to hydrostatic shell pressure test and shall not show any leaks.

This specification covers a group of common requirements that, unless covered by the individual product specification in another ASTM document, applies to steel and alloy castings for use in general industrial applications. Materials shall be produced by open-hearth or electric furnace process with or without separate refining, such as argon-oxygen-decarburization (AOD), and then consequently heat treated in the working zone. Castings shall receive heat and product analysis to evaluate their conformance to chemical composition requirements. Mechanical requirements shall also be assessed. The surfaces of castings shall be free of adhering sand, scale, cracks, hot tears, and other surface discontinuities. Repair welding may be performed as required.

This specification is concerned with insulating covers for use on exposed drain and water supply piping under accessible lavatories and sinks.

The insulating covers shall be removable and reusable, and shall satisfy the requirements of the Americans with Disabilities Act 4.19.4: 2010 Americans with Disabilities Act Standard for Accessible Design Section 606.5, ICC/ANSI A117.1 2012 (Standard for Accessible and Usable Buildings and Facilities - for Persons with Physical Disabilities) section 606.6 (Exposed Pipes and Surfaces).Included in this specification are criteria for classifying removable and reusable protective covers on exposed drain and water supply piping under lavatories and sinks, along with methods of marking or labeling. All products shall conform to specified requirements for dimensions; form and installation; workmanship, finish, and appearance; apparent material thermal conductivity; water absorption; surface burning characteristics; rate of burning; fungi growth; water temperature and pH; surface deflection and load; and cracks or voids.

This specification covers the chemical and physical requirements of municipal ferrous scrap that are intended for use by such industries listed as follows: copper industry, iIron and steel foundries, iron and steel production, detinning industry, and ferroalloy industry. Municipal ferrous scrap shall conform to the requirements as to chemical composition for the respective end uses prescribed. Also, municipal ferrous scrap shall conform to the physical properties for the respective end uses prescribed.

This specification covers machine-made glass-fiber-reinforced thermosetting-resin pressure pipe manufactured by the centrifugal casting process. Pipe covered by this specification has been found suitable for conveying gases, petroleum products, or corrosive fluids. For the purposes of this standard, polymer does not include natural polymers. Pipe meeting this specification shall be categorized by the prescribed long-term static or cyclic hydrostatic design basis when tested. Additionally, the pipe shall meet the applicable cell limit requirements for short-term rupture strength, longitudinal tensile strength, tensile modulus, and pipe stiffness.

This specification covers steel castings, general requirements, for pressure-containing parts. The steel shall be made by open-hearth or electric-furnace process, with or without separate refining such as argon-oxygen-decarburization (AOD), unless otherwise designated by the individual specification. Ferritic and martensitic steel shall be cooled after pouring to provide substantially complete transformation of austenite prior to heat treatment to enhance mechanical properties. The material shall conform to the specified chemical composition requirements. An analysis of each heat shall be made by the manufacturer to determine the percentages of the elements specified. The mechanical test methods and definitions are presented in details. One tension test shall be made from each heat, and shall conform to the tensile requirements specified. Test coupons shall be cast from the same heat as the castings represented, except that for investment castings, the test coupons shall be cast in the same type of mold as the castings. After machining, each casting shall be tested under specified hydrostatic shell test pressures in the applicable steel rating for which the casting is designed.

This practice is intended as an aid for establishing a suitable procedure for the heat treatment of magnesium alloys to achieve the proper physical and mechanical properties. Air chamber furnaces that may be either electrically heated, or oil- or gas-fired, are usually used for the heat treatment process. Each furnace must be gas tight, have suitable equipment for protective atmosphere, be equipped with a high-velocity fan or any other comparable means for circulating the atmosphere, and designed so that no direct radiation from the heating elements or impingement of the flame on the magnesium. It is also important that the furnace be calibrated before it is used initially and after any change in the furnace. Likewise, temperature-measurement systems should be regularly checked for accuracy.

This specification covers the basic properties of thermoset molding plastic compounds and the test methods used to establish the properties. The plastic compounds shall be a resin, cellulose-filled or mineral/glass-filled phenolic, melamine, polyester, diallyl iso-phthalate, diallyl ortho-phthalate, silicone, or epoxy. Standard test specimens shall be in the as-received condition or shall be conditioned before testing by humidity, immersion, or temperature conditioning. The specimens shall undergo mechanical or physical qualification tests which shall conform to the following properties: compressive strength; dimensional stability; flexural strength; heat deflection temperature; heat resistance; impact strength; tensile strength; and water absorption. Electrical qualification tests shall be conducted; wherein, the specimens shall comply with the following requirements: arc resistance; dielectric breakdown; dielectric constant; dielectric strength; dissipation factor; surface resistance; comparative track index; volume resistance; and water extract conductance. Tests for combustion qualification shall also be performed to determine the flame resistance ignition time, burning time, flammability, and toxicity requirements. Batch acceptance tests shall be conducted as well to ensure the quality conformance of the specimens.

This specification covers totally reactive epoxy resins supplied as liquids or solids that can be used for castings, coatings, tooling, potting, adhesives, or reinforced applications. The epoxy resins described also can be used as stabilizers and cross-linking agents; and they can be combined with other reactive products. The resins covered contain no hardeners. The six resin types covered in this specification are divided into specific groups by their chemical nature. The materials shall conform to the required viscosity, Mettler softening point, and color.
