16、C700, West Conshohocken, PA 19428-2959. United States14. 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 of product specificatio
17、ns 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 steel, stainless steel, an
18、d 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 Manual to ensure consisten
19、cy.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 specificationmay require t
20、he 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 requirement becomes the sec

Section Contents6.1 Title:6.1.1 The title should be as concise as possible, but
26、 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 and are at the option of
27、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 Elevated Temperatures.” A gene
28、ral 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: “carbon,” “high-streng
29、th 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,” “ofcommercial quality,” etc., and6
30、.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 because itfacilitates accu
31、rate 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 developing a title with this f
32、ormat 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 stainless,” etc.,6.1.4.5 Spe

34、ct, if any: “for machine parts,” “for valves,” “for low temperature,” “for generaluse,” “for corrosive service,” etc.6.1.5 The use of temperature categories in the titles of specifications should be avoided. When a subcommittee determines thattemperature categories mustshould be used in the title of
35、 a specific standard, numerical temperature ranges should not be used; theestablishment of limits on the use of materials is not the responsibility of Committee A01. When a subcommittee determines thata temperature category mustshould be used in a title, one of the following should be selected: cryo
36、genic, low, ambient, moderate,elevated, or high.6.2 Scope:A994 1636.2.1 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 prope
37、rty, or application ofthe product. Further subdivision should be by 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 grad
38、e, class, and type is the A01 preferred style, and it should be used 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 ar
39、eprovided for use at the option of the purchaser. Thesupplementary requirements 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-Pou
40、nd Units: For a standard citing inch-pound units of measurement as thestandard 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. The values gi
41、ven in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered standard.Units to Be Used in StandardWithin the text, inch-pound units shall appear first followed by non-rationalized SI units inparentheses.6.2.3.2 Format Requirements for Standa
42、rds in SI Units: For a standard citing SI units of measurement as the standard units ofmeasurement, select the type of SI standard to be written and follow the appropriate format requirement listed below:(1) Solely SI Standards:In the ScopeInclude the following in the scope as a numbered paragraph:I
43、.X UnitsThe values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.Units to Be Used in Standard2Within the text,show only rationalized SI units.(2) Combined Standards:In the ScopeInclude the following in the scope as a numbered paragraph:I
44、.X UnitsThis specification is expressed in both inch-poundunits and in SI units; however, unless the purchase order orcontract specifies the applicable M specification designation(SI units), the inch-pound units shall apply. The values statedin either inch-pound units or SI units are to be regardeds
45、eparately as standard. Within the text, the SI units are shownin brackets. The values stated in each system may not beexact equivalents; therefore, each system shall be usedindependently of the other. Combining values from the twosystems may result in nonconformance with the standard.6.2.4 In a gene
46、ral requirements specification, the scope should contain the following, or similar, statement:In the case of conflict between a requirement of a productspecification and a requirement of this specification, theproduct specification takes precedence. In the case of conflictbetween a requirement of th
47、e product specification and arequirement of this specification and a more stringentrequirement of the purchase order or contract, the purchaseorder or contract takes precedence. The purchase order orcontract requirements shall not take precedence if they, in anyway, violate the requirements of the p
48、roduct specification orthis specification; for example, by the waiving of a testrequirement or by making a test requirement less stringent.6.2.5 Temperature Categories:6.2.5.1 Temperature categories should not be used in the scopes of specifications, because that use may mislead users ofstandards by
49、 creating an implication that the scope reflects engineering judgment on the temperature suitability of products forspecific applications. The establishment of temperature limitations on the use of materials is the responsibility of code committees.6.2.5.1 When a subcommittee determines that temperature categories mustshould be used in a specific standard, numericaltemperature ranges should not be used. The categories should be limited to the following: cryogenic, low, ambient, moderate,elevated, or high.6.2.5.2 When a temperature category is used in the scope of a stan
