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,thos

18、e used should be listed in 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 use

24、ction Contents6.1 Title:6.1.1 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

25、for establishing wording 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

26、 Plate, Sheet, and Stripfor 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.

27、3.3 Material type based on chemical composition:“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 im-proved toughness,” “with

28、mechanical property 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.A994 1326.1.4 The key word in order of importance concept forspecifi

29、cation titles is preferred by 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

30、 at Elevated Temperatures.” A general scheme fordeveloping 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:“

31、carbon,” “high-strength 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,”“com

32、mercial quality,” 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

33、 deter-mines that 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 u

34、sed in a title,one 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 b

35、ased upon chemical 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, o

36、r generic classification. 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:Suppl

37、ementary requirements of an optional nature areprovided 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 thefollowing:6.2.3.1

38、Format Requirements for Standards in Inch-PoundUnits: For a standard citing inch-pound units of measurementas the standard units of measurement, follow the formatrequirement below:In the ScopeInclude the following in the scope as anumbered paragraph:I.X Units-The values stated in inch-pound units ar

39、e to beregarded as standard. The values given 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-poundunits shall appear first followed by non-rationalized SI units inparenthes

40、es.6.2.3.2 Format Requirements for Standards in SI Units: Fora standard citing SI units of measurement as the standard unitsof measurement, select the type of SI standard to be written andfollow the appropriate format requirement listed below:(1) Solely SI Standards:In the ScopeInclude the following

41、 in the scope as anumbered paragraph:I.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

42、 in the scope as anumbered paragraph:I.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

43、 units or SI units are to be regardedseparately 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 nonconform

44、ance 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, theproduct specification takes precedence. In the case o

45、f conflictbetween a requirement of the 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 anyw

46、ay, violate the requirements of the product 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 thescopes of specifications, because that

47、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 a s

48、ubcommittee determines that temperaturecategories must be used in a specific standard, numericalA994 133temperature 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 scop

49、e ofa 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 specification.Low (or cryogenic) temperatures are temperatures wherefracture toughness is important.6.2.6 Specifications that reference general requirementsmay include the following statement in the scope:The following referenced general requirements areindispensable for the appl
