Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Manganese-Silicon (Withdrawn 2004)

Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Manganese-Silicon (Withdrawn 2004)

SCOPE
1.1 This specification covers chromium-manganese-silicon alloy steel plates, intended particularly for welded boilers and other pressure vessels.
1.2 Plates under this specification are available in two grades having strength levels as follows: Grade Tensile Strengthksi [MPa]A 75-95 [515-655]B 85-110 [585-760]
1.3 The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current practice normally limits the maximum thickness of plates furnished under this specification to 2 in. [50 mm].
1.4 Grade A is suitable for rivets and when so used the bars shall be subject to the requirements for rolled bars specified in Specification A 31, except for the chemical and mechanical requirements.
1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents. Therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
WITHDRAWN RATIONALE
This specification covers chromium-manganese-silicon alloy steel plates, intended particularly for welded boilers and other pressure vessels.
Formerly under the jurisdiction of Committee A01 on Steel, Stainless Steel, and Related Alloys, this specification was withdrawn in September 2004 because there is no indication that the specification is being used or that material pertaining to it is being produced.

Standard Test Methods and Definitions for Mechanical Testing of Steel Products

SIGNIFICANCE AND USE
4.1 The primary use of these test methods is testing to determine the specified mechanical properties of steel, stainless steel, and related alloy products for the evaluation of conformance of such products to a material specification under the jurisdiction of ASTM Committee A01 and its subcommittees as designated by a purchaser in a purchase order or contract.  
4.1.1 These test methods may be and are used by other ASTM Committees and other standards writing bodies for the purpose of conformance testing.  
4.1.2 The material condition at the time of testing, sampling frequency, specimen location and orientation, reporting requirements, and other test parameters are contained in the pertinent material specification or in a general requirement specification for the particular product form.  
4.1.3 Some material specifications require the use of additional test methods not described herein; in such cases, the required test method is described in that material specification or by reference to another appropriate test method standard.  
4.2 These test methods are also suitable to be used for testing of steel, stainless steel and related alloy materials for other purposes, such as incoming material acceptance testing by the purchaser or evaluation of components after service exposure.  
4.2.1 As with any mechanical testing, deviations from either specification limits or expected as-manufactured properties can occur for valid reasons besides deficiency of the original as-fabricated product. These reasons include, but are not limited to: subsequent service degradation from environmental exposure (for example, temperature, corrosion); static or cyclic service stress effects, mechanically-induced damage, material inhomogeneity, anisotropic structure, natural aging of select alloys, further processing not included in the specification, sampling limitations, and measuring equipment calibration uncertainty. There is statistical variation in all aspects of mechanical testin...
SCOPE
1.1 These test methods2 cover procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys. The various mechanical tests herein described are used to determine properties required in the product specifications. Variations in testing methods are to be avoided, and standard methods of testing are to be followed to obtain reproducible and comparable results. In those cases in which the testing requirements for certain products are unique or at variance with these general procedures, the product specification testing requirements shall control.

ASTM D7816-23(Test Method)
Standard Test Method for Enumeration of Halophilic and Proteolytic Bacteria in Raceway Brine, Brine-Cured Hides and Skins

SIGNIFICANCE AND USE
4.1 This test method enumerates salt tolerant (halophilic) bacteria, and proteolytic bacteria that are also salt tolerant. Under the conditions of this test method those bacteria are equated as halophilic organisms. Salt tolerant proteolytic bacteria have been known to cause damage to hides and skins in raceway brine.
SCOPE
1.1 This test method covers the enumeration of bacteria that can tolerate high salt concentrations or can hydrolyze protein/collagen, or both. This test method is applicable to raceway brine, brine-cured hides and skins, and pre-charge raceway liquor.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM C488-16(2023)(Test Method)
Standard Test Method for Conducting Exterior Exposure Tests of Finishes for Thermal Insulation

SIGNIFICANCE AND USE
5.1 Both physical and chemical changes possibly occur from weather exposure, and these changes affect performance properties, service life, and maintenance schedules. For this reason, tests of properties relating to performance shall be made both before and after specific periods of outdoor exposure.  
5.2 This test method recognizes that differing geographical locations, environmental conditions, differences between surface temperatures and ambient temperatures, and test durations have extremely varied effects upon the test results.  
5.3 This test method is to be used for comparative qualitative testing.
SCOPE
1.1 This test method covers out-of-doors exposure testing of finishes that are normally field-applied to thermal insulation and possibly include joints or joint sealants, or both. Such exposure is essential prior to the determination of certain physical properties when the finish is to be exposed to exterior weather conditions. This test method also indicates possible compatibility problems between the joint sealant and the finish as well as the ability of the finish to span a dry joint. This test method is not intended to evaluate mildew resistance, efflorescence, or chemical resistance.  
Note 1: For testing free plastic films, see Practice D1435.  
1.2 This test method does not prescribe the method of application, test duration, or inspection intervals.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E527-23(Practice)
Standard Practice for Numbering Metals and Alloys in the Unified Numbering System (UNS)

SIGNIFICANCE AND USE
4.1 The UNS provides a means of correlating many nationally used numbering systems currently administered by societies, trade associations, and individual users and producers of metals and alloys, thereby avoiding confusion caused by use of more than one identification number for the same material; and by the opposite situation of having the same number assigned to two or more entirely different materials. It also provides the uniformity necessary for efficient indexing, record keeping, data storage and retrieval, and cross referencing.  
4.2 A UNS number is not in itself a specification, since it establishes no requirements for form, condition, quality, etc. It is a unified identification of metals and alloys for which controlling limits have been established in specifications published elsewhere.
Note 5: Organizations that issue specifications should report to appropriate UNS number-assigning offices (3.1.2) any specification changes that affect descriptions shown in published UNS listings.
SCOPE
1.1 This practice (Note 1) covers a unified numbering system (UNS) for metals and alloys that have a “commercial standing” (see Note 2), and covers the procedure by which such numbers are assigned. Section 2 describes the system of alphanumeric designations or “numbers” established for each family of metals and alloys. Section 3 outlines the organization established for administering the system. Section 5 describes the procedure for requesting number assignment to metals and alloys for which UNS numbers have not previously been assigned.
Note 1: UNS designations are not to be used for metals and alloys that are not registered under the system described herein, or for any metal or alloy whose composition differs from those registered.
Note 2: The terms “commercial standing,” “production usage,” and other similar terms are intended to apply to metals and alloys in active commercial production and use, although the actual amount of such use will depend, among other things, upon the type of metals and alloys involved and their application.
The various standardizing organizations involved with the individual industries apply their own established criteria to define the status of a metal or alloy in terms of when a UNS designation number will be assigned. For instance, ASTM Committee A01 requires details of heat analysis, mechanical properties, and processing requirements for addition of a new grade or alloy to its specifications. The Copper Development Association requires that the material be “in commercial use (without tonnage limits);” the Aluminum Association requires that the alloy be “offered for sale (not necessarily in commercial use);” the SAE Aerospace Materials Division calls for “repetitive procurement by at least two users.”
Thus, while no universal definition for usage criteria is established, the UNS numbers are intended to identify metals and alloys that are generally in regular production and use. A UNS number will not ordinarily be issued for a material that has just been conceived or that is still in only experimental trial.  
1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Steel Forgings, General Requirements

ABSTRACT
This specification covers a group of common requirements that, unless covered by the individual product specification in another ASTM document, applies to steel forgings for general use. Materials shall be produced primarily by either electric-furnace, basic oxygen, vacuum-induction (VIM), or open-hearth melting process. The primary melting may incorporate separate degassing or refining and may be followed by secondary melting, using electro slag (ESR) or vacuum arc remelting (VAR). Steel shall be forged by any of these three classes based on forging temperature: cold-worked forging, hot-cold-worked forging, or hot-worked forging. After forging, specimens shall be allowed to cool prior to reheating for heat treatment. Details of heat and product analyses for the evaluation of chemical composition are thoroughly discussed. Tension and hardness tests shall be conducted to evaluate mechanical properties such as percentage of elongation and reduction of area. Repair welding shall not be allowed unless permitted by the product specification.
SCOPE

ASTM A747/A747M-23(Specification)
Standard Specification for Steel Castings, Stainless, Precipitation Hardening

ABSTRACT
This specification covers iron-chromium-nickel-copper corrosion resistance steel castings capable of being strengthened by precipitation hardening heat treatment. The steel shall be made by electric furnace process with or without separate refining such as argon-oxygen decarburization. The steel materials shall also undergo homogenization heat treatment, solution annealing heat treatment, precipitation hardening and shall conform to the required values of temperature and time and cooling treatment. The materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, copper, columbium, and nitrogen.
SCOPE
1.1 This specification covers iron-chromium-nickel-copper corrosion-resistant steel castings, capable of being strengthened by precipitation hardening heat treatment.  
1.2 These castings may be used in services requiring corrosion resistance and high strengths at temperatures up to 600 °F [315 °C]. They may be machined in the solution heat-treated condition and subsequently precipitation hardened to the desired high-strength mechanical properties specified in Table S51.1 with little danger of cracking or distortion.  
1.3 The material is not intended for use in the solution heat-treated condition.  
Note 1: If the service environment in which the material is to be used is considered conducive to stress-corrosion cracking, precipitation hardening should be performed at a temperature that will minimize the susceptibility of the material to this type of attack.  
1.4 Supplementary requirements of an optional nature are provided for use at the option of the purchaser. The supplementary requirements shall apply only when specified individually by the purchaser in the purchase order or contract.  
1.5 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M-specification designation (SI units), the inch-pound units shall apply.  
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. Within the text, the SI units are shown in brackets.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM F3441-23a(Guide)
Standard Guide for Measurement of pH Below Resilient Flooring Installations

SIGNIFICANCE AND USE
4.1 There is typically a higher concentration of soluble alkali salts in the surface region of a concrete slab due to the initial bleeding process of a freshly placed concrete slab. If after a resilient floor covering material is installed there is sufficient moisture within the slab to place these salts into solution a potentially damaging high pH solution can develop beneath the installed material.  
4.2 Results obtained through the use of this guide indicate the comparative pH of reagent water placed on properly prepared concrete slab surfaces only at the time of the procedure and in the specific locations evaluated.  
4.3 If pre-installation surface pH evaluation is required by the manufacturer of the resilient flooring, adhesive, patching/underlayment products or project specifications, their instructions and limitations should be consulted.
SCOPE
1.1 This guide discusses procedures that may be used for evaluating the comparative change in pH of reagent water placed on the surface of a properly prepared concrete slab surface.  
1.2 This guide is intended to be used in conjunction with the flat surface electrode pH meter manufacturer’s calibration procedures, operation instructions, and interpretive data where available.

Standard Practice for Analysis and Interpretation of Light-Water Reactor Surveillance Neutron Exposure Results

SIGNIFICANCE AND USE
3.1 The objectives of a reactor vessel surveillance program are twofold. The first requirement of the program is to monitor changes in the fracture toughness properties of ferritic materials in the reactor vessel beltline region resulting from exposure to neutron irradiation and the thermal environment. The second requirement is to make use of the data obtained from the surveillance program to determine the conditions under which the vessel can be operated throughout its service life.  
3.1.1 To satisfy the first requirement of 3.1, the tasks to be carried out are straightforward. Each of the irradiation capsules that comprise the surveillance program may be treated as a separate experiment. The goal is to define and carry to completion a dosimetry program that will, a posteriori, describe the neutron field to which the material test specimens were exposed. The resultant information will then become part of a database applicable in a stricter sense to the specific plant from which the capsule was removed, but also in a broader sense to the industry as a whole.  
3.1.2 To satisfy the second requirement of 3.1, the tasks to be carried out are somewhat complex. The objective is to describe accurately the neutron field to which the pressure vessel itself will be exposed over its service life. This description of the neutron field must include spatial gradients within the vessel wall. Therefore, heavy emphasis must be placed on the use of neutron transport techniques as well as on the choice of a design basis for the computations. Since a given surveillance capsule measurement, particularly one obtained early in plant life, is not necessarily representative of long-term reactor operation, a simple normalization of neutron transport calculations to dosimetry data from a given capsule may not be appropriate (1-67).  
3.2 The objectives and requirements of a reactor vessel's support structure's surveillance program are much less stringent, and at present, are limited to ...
SCOPE
1.1 This practice covers the methodology, summarized in Annex A1, to be used in the analysis and interpretation of neutron exposure data obtained from LWR pressure vessel surveillance programs and, based on the results of that analysis, establishes a formalism to be used to evaluate present and future condition of the pressure vessel and its support structures2 (1-74).3  
1.2 This practice relies on, and ties together, the application of several supporting ASTM standard practices, guides, and methods (see Master Matrix E706) (1, 5, 13, 48, 49).2 In order to make this practice at least partially self-contained, a moderate amount of discussion is provided in areas relating to ASTM and other documents. Support subject areas that are discussed include reactor physics calculations, dosimeter selection and analysis, and exposure units.  
1.3 This practice is restricted to direct applications related to surveillance programs that are established in support of the operation, licensing, and regulation of LWR nuclear power plants. Procedures and data related to the analysis, interpretation, and application of test reactor results are addressed in Practice E1006, Guide E900, and Practice E1035.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
