17、ide, refer to the Form and Style Manual, Terminology A941, and Terminology E6.4. Significance and Use4.1 The Form and Style Manual provides mandatory requirements and recommended practices for the preparation and contentof ASTM specifications. In order to promote consistency in the style and content
18、 of product specifications under its jurisdiction,Committee A01 recognizes the need to provide a supplementary document pertaining to the types of products and materialscovered by those specifications.4.2 This guide contains a list of sections to be considered for inclusion in a specification for st
19、eel, stainless steel, and relatedalloy products, and guidance or recommended wording, or both, for such sections.4.3 Persons drafting new product specifications, or modifying existing ones, under the jurisdiction of Committee A01, shouldfollow this guide and the requirements of the Form and Style Ma
20、nual to ensure consistency.5. Subject Headings of Text5.1 The various sections of a Committee A01 product specification should be arranged in the following order. Not all of thesesections will appear in every specification; however, those used should be listed in the order given. In some cases, a sp
21、ecificationmay require the addition of a section or sections not listed, in which case they should be inserted in the specification so as topreserve the logical sequence of sections, insofar as possible.5.2 When only one requirement is used in a section having multiple possible subheadings, that req
22、uirement becomes the sectionheading (for example, Tension Test instead of Mechanical Properties).TitleDesignationScopeReferenced DocumentsASTM StandardsOther DocumentsClassificationTerminologyOrdering InformationGeneral RequirementsMaterials and ManufactureMelting PracticeMechanical Working Practice

Section Contents6.1 Title:6.1.1 The title should be as
27、concise as possible, but complete enough to identify clearly the product covered by the specification.Titles are also used in lists, table of contents, and indexes, and it is most important that they be brief but self-explanatory.6.1.2 Two methods for establishing wording are considered acceptable a
28、nd are at the option of the subcommittee.6.1.3 One is to word as in ordinary conversation with the adjectives first as is normal in the English language. For example,“Standard Specification for Hot-Worked, Hot-Cold-Worked, and Cold-WorkedAlloy Steel Plate, Sheet, and Strip for High Strengthat Elevat
29、ed Temperatures.” A general scheme for 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: “quenched and tempered,” “hot-rolled,” “seamless,” “welded,” etc.,6.1.3.3 Material type based on chemical composition
30、: “carbon,” “high-strength low-alloy,” “austenitic stainless,” etc.,6.1.3.4 “Steel,”6.1.3.5 Product form: “bars,” “pressure vessel plate,” “casting,” “sheet and strip,” etc.,6.1.3.6 Special quality of the product, if any: “with improved toughness,” “with mechanical property requirements,” “ofcommerc
31、ial quality,” etc., and6.1.3.7 Specific application or use of the product, if any: “for machine parts,” “for valves,” “for low temperature,” “for generaluse,” “for corrosive service,” etc.6.1.4 The key word in order of importance concept for specification titles is preferred by many subcommittees be
32、cause itfacilitates accurate indexing and provides rapid identification of specification subject matter. For example, “Standard Specificationfor Steel Plate, Sheet, and Strip, Alloy, Hot-Worked, Hot-Cold-Worked, and Cold-Worked, for High Strength at ElevatedTemperatures.” A general scheme for develo
33、ping a title with this format is:6.1.4.1 Type of document: “Standard Specification for,”6.1.4.2 “Steel,”6.1.4.3 Product form: “bars,” “pressure vessel plate,” “casting,” “sheet and strip,” etc.,6.1.4.4 Material type based on chemical composition: “carbon,” “high-strength low-alloy,” “austenitic stai
34、nless,” etc.,6.1.4.5 Special treatment of the material, if any: “quenched and tempered,” “hot-rolled,” “seamless,” “welded,” etc.,6.1.4.6 Special quality of the product, if any: “with improved toughness,” “with mechanical property requirements,”“commercial quality,” etc., and6.1.4.7 Specific applica
35、tion or use of the product, if any: “for machine parts,” “for valves,” “for low temperature,” “for generaluse,” “for corrosive service,” etc.6.1.5 When a subcommittee determines that temperature categories should be used in the title of a specific standard, numericaltemperature ranges should not be
36、used; the establishment of limits on the use of materials is not the responsibility of CommitteeA994 183A01. When a subcommittee determines that a temperature category should be used in a title, one of the following should beselected: cryogenic, low, ambient, moderate, elevated, or high.6.2 Scope:6.
37、2.1 When the specification covers multiple grades, classes, types, or combinations thereof, this should be stated in a separatesection in the scope. The subdivision grade should be based upon chemical composition, a mechanical property, or application ofthe product. Further subdivision should be by
38、class, based on some pertinent property or properties, and identified by arabicnumbers. The subdivision type should be based on some major property, such as manufacture, product form, or genericclassification. The precedence of grade, class, and type is the A01 preferred style, and it should be used
39、 in the absence of anyestablished preference.6.2.2 When a specification has supplementary requirements, the scope should include the following, or similar, statement as asubsection:Supplementary requirements of an optional nature areprovided for use at the option of the purchaser. Thesupplementary r
40、equirements shall apply only when specifiedindividually by the purchaser in the purchase order or contract.6.2.3 Scope statements relating to units should be one of the following:6.2.3.1 Format Requirements for Standards in Inch-Pound Units: For a standard citing inch-pound units of measurement as t
41、hestandard units of measurement, follow the format requirement below:In the ScopeInclude the following in the scope as a numbered paragraph:I.X Units-The values stated in inch-pound units are to beregarded as standard.
