17、the requirements of the Form andStyle Manual to ensure consistency.5. Subject Headings of Text5.1 The various sections of a Committee A01 productspecification should be arranged in the following order. Not allof these sections will appear in every specification; however,those used should be listed i
18、n the order given. In some cases,a specification may require the addition of a section or sectionsnot listed, in which case they should be inserted in thespecification so as to preserve the logical sequence of sections,insofar as possible.5.2 When only one requirement is used in a section havingmult
19、iple possible subheadings, that requirement becomes thesection heading (for example, Tension Test instead of Mechani-cal Properties).TitleDesignationScopeReferenced DocumentsASTM StandardsOther DocumentsClassificationTerminologyOrdering InformationGeneral RequirementsMaterials and ManufactureMelting

Section Contents6.1 Title:6
24、1.1 The title should be as concise as possible, but com-plete enough to identify clearly the product covered by thespecification. Titles are also used in lists, table of contents, andindexes, and it is most important that they be brief butself-explanatory.6.1.2 Two methods for establishing wording
25、are consideredacceptable and are at the option of the subcommittee.6.1.3 One is to word as in ordinary conversation with theadjectives first as is normal in the English language. Forexample, “Standard Specification for Hot-Worked, Hot-Cold-Worked, and Cold-Worked Alloy Steel Plate, Sheet, and Stripf
26、or High Strength at Elevated Temperatures.”Ageneral schemefor generating titles with this format is:6.1.3.1 Type of document: “Standard Specification for,”6.1.3.2 Special treatment of the material, if any: “quenchedand tempered,” “hot-rolled,” “seamless,” “welded,” etc.,6.1.3.3 Material type based o
27、n chemical composition: “car-bon,” “high-strength low-alloy,” “austenitic stainless,” etc.,6.1.3.4 “Steel,”6.1.3.5 Product form: “bars,” “pressure vessel plate,” “cast-ing,” “sheet and strip,” etc.,6.1.3.6 Special quality of the product, if any: “with im-proved toughness,” “with mechanical property
28、requirements,”“of commercial quality,” etc., and6.1.3.7 Specific application or use of the product, if any:“for machine parts,” “for valves,” “for low temperature,” “forgeneral use,” “for corrosive service,” etc.6.1.4 The key word in order of importance concept forspecification titles is preferred b
29、y many subcommittees be-cause it facilitates accurate indexing and provides rapid iden-tification of specification subject matter. For example, “Stan-dard Specification for Steel Plate, Sheet, and Strip, Alloy,Hot-Worked, Hot-Cold-Worked, and Cold-Worked, for HighStrength at Elevated Temperatures.”
30、A general scheme fordeveloping a title with this format is:6.1.4.1 Type of document: “Standard Specification for,”A9940526.1.4.2 “Steel,”6.1.4.3 Product form: “bars,” “pressure vessel plate,” “cast-ing,” “sheet and strip,” etc.,6.1.4.4 Material type based on chemical composition: “car-bon,” “high-st
31、rength low-alloy,” “austenitic stainless,” etc.,6.1.4.5 Special treatment of the material, if any: “quenchedand tempered,” “hot-rolled,” “seamless,” “welded,” etc.,6.1.4.6 Special quality of the product, if any: “with im-proved toughness,” “with mechanical property requirements,”“commercial quality,
32、 etc., and6.1.4.7 Specific application or use of the product, if any:“for machine parts,” “for valves,” “for low temperature,” “forgeneral use,” “for corrosive service,” etc.6.1.5 The use of temperature categories in the titles ofspecifications should be avoided. When a subcommittee deter-mines tha
33、t temperature categories must be used in the title of aspecific standard, numerical temperature ranges should not beused; the establishment of limits on the use of materials is notthe responsibility of Committee A01. When a subcommitteedetermines that a temperature category must be used in a title,o
34、ne of the following should be selected: cryogenic, low,ambient, moderate, elevated, or high.6.2 Scope:6.2.1 When the specification covers multiple grades,classes, types, or combinations thereof, this should be stated ina separate section in the scope. The subdivision grade shouldbe based upon chemic
35、al composition, a mechanical property, orapplication of the product. Further subdivision should be byclass, based on some pertinent property or properties, andidentified by arabic numbers. The subdivision type should bebased on some major property, such as manufacture, productform, or generic classi
36、fication. The precedence of grade, class,and type is the A01 preferred style, and it should be used in theabsence of any established preference.6.2.2 When a specification has supplementary requirements,the scope should include the following, or similar, statement asa subsection:Supplementary require
37、ments of an optional nature are pro-vided for use at the option of the purchaser. The supplemen-tary requirements shall apply only when specified individuallyby the purchaser in the purchase order or contract.6.2.3 When a specification is a combined standard, thescope should include the following, o
38、r similar, statement as asubsection:This specification is expressed in both inch-pound units and inSI units; however, unless the purchase order or contract speci-fies the applicable M specification designation (SI units), theinch-pound units shall apply. The values stated in either inch-pound units
39、or SI units are to be regarded separately as stan-dard. Within the text, the SI units are shown in brackets. Thevalues stated in each system may not be exact equivalents;therefore, each system shall be used independently of theother. Combining values from the two systems may result innonconformance
40、with the standard.6.2.4 In a general requirements specification, the scopeshould contain the following, or similar, statement:In the case of conflict between a requirement of a productspecification and a requirement of this specification, the prod-uct specification takes precedence. In the case of c
41、onflict be-tween a requirement of the product specification and a require-ment of this specification and a more stringent requirement ofthe purchase order or contract, the purchase order or contracttakes precedence. The purchase order or contract require-ments shall not take precedence if they, in a
42、ny way, violate therequirements of the product specification or this specification;for example, by the waiving of a test requirement or by makinga test requirement less stringent.6.2.5 Temperature Categories:6.2.5.1 Temperature categories should not be used in thescopes of specifications, because th
43、at use may mislead users ofstandards by creating an implication that the scope reflectsengineering judgment on the temperature suitability of prod-ucts for specific applications. The establishment of temperaturelimitations on the use of materials is the responsibility of codecommittees.6.2.5.2 When
44、a subcommittee determines that temperaturecategories must be used in a specific standard, numericaltemperature ranges should not be used. The categories shouldbe limited to the following: cryogenic, low, ambient, moderate,elevated, or high.6.2.5.3 When a temperature category is used in the scope ofa
45、 standard, the scope should cite the property or properties ofthe specified material that explain the selection of the tempera-ture category with a statement such as:Elevated temperatures are temperatures in the range wherecreep and stress rupture properties are important for the steelsin this speci
46、fication.Low (or cryogenic) temperatures are temperatures where frac-ture toughness is important.6.2.6 Specifications that reference general requirementsmay include the following statement in the scope:The following referenced general requirements are indispens-able for the application of this speci
47、fication: Specification AXXX.6.2.7 Definitions of the various product forms should beaddressed in the section on Terminology, rather than in theScope section.6.3 Referenced Documents:Populate this section last, listing in alphanumeric sequencethe designation and complete title of all documents refer
