1、Designation: A1067/A1067M 12 A1067/A1067M 12aStandard Specification forTest Coupons for Steel Castings1This standard is issued under the fixed designation A1067/A1067M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of la

2、st revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification defines the geometries of several separately-cast and integrally-cast test coupons for use as specif

3、ied inthe applicable casting product or common requirements standard. This standard does not address procedures for molding, casting,heat treating, machining, or testing; these items are addressed as needed and appropriate by the applicable product or commonrequirements standard.NOTE 1The test coupo

4、ns described herein were formerly defined in multiple casting specifications. Those standards now reference this documentwhen test coupons are required and should be consulted for applicable manufacturing and processing requirements.1.2 UnitsThe values stated in either SI units or inch-pound units a

5、re to be regarded separately as standard. The values statedin each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with the standard.1.3 This standard does not purport to address

6、all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2. Ordering Information2.1 The applicable casting product stand

7、ard or common requirements standard or both provide information regarding thenumber of coupons, molding materials to be used, heat treatment concerns, and other processing issues.3. Materials and Manufacture3.1 Unless specified otherwise by the purchaser, test coupons shall be poured from the same h

8、eat, or from the same master heat,or from a sub-heat from the same master heat as the castings they are to represent.3.2 Except where specified herein or in the applicable product or common requirements standard, the details of the gating andrisering of the coupons are left to the discretion of the

9、producer.3.3 The test coupons shall be processed and heat-treated as specified in the applicable product or common requirementsspecification. Except when specified otherwise, the portion of the test coupon from which the test specimen or specimens are tobe machined may be cut from the riser or feede

10、r prior to heat treatment.4. Performance Requirements4.1 The primary function of the test coupon is to provide sound specimens useable for the determination of mechanical,physical, corrosion, or other properties of the metal used to produce the castings. If the test results conform to the statedrequ

11、irements, then the test coupon may be considered to have functioned acceptably.5. Other Requirements5.1 The casting producer shall establish procedures for the identification and traceability of the coupons from pouring throughtesting.6. Dimensions and Permissible Variations6.1 The drawings shown in

12、 this standard are not necessarily drawn to scale. The values shown in the tables constitute thedimensional requirements.6.2 The drawings shown in this standard depict the more commonly used test coupons (Figs. 1-9). Other designs may be suitablewhen shown to produce acceptable properties or where a

Workmanship, Finish, and Appearance7.1 Care should be taken in the preparation and pouring of the molds to avoid

14、 the creation of inclusions or other anomalies inthe resulting test specimens.8. Sampling8.1 Care shall be taken in the production and processing of the test coupon to assure that it is representative of the casting orcastings it represents.1 This specification is under the jurisdiction of ASTM Comm

23、l CastingsA1067/A1067M 12a7SUPPLEMENTARY REQUIREMENTSThere are currently no supplementary requirements for this standard.APPENDIX(Nonmandatory Information)X1. MOLD MATERIALX1.1 A test coupon is used to demonstrate that the metal can obtain the specified minimum properties, not that the casting hasce

24、rtain properties. Thus it serves as a check of the composition and heat treatment. It is not (and cannot be) a check of the gatingand feeding system used for the casting or of any of the other processing variables.X1.2 Since the coupons are used to demonstrate the capability of the metal, any design

25、 that produces compliant properties shouldbe acceptable. There are a few exceptions:X1.2.1 The mold material used for the test coupons must not be a more powerful chill than the material used for the casting.(Chilling may provide improved properties in some instances.) Conversely, test coupons may b

26、e produced using a mold materialthat is a less powerful chill (more insulating) than that used for the casting.X1.2.2 In the case of a heavy section casting, a heavy section coupon may be appropriate for thickness-sensitive alloys. (This isrelated to the chilling issue; a thin section test coupon co

27、ols more quickly than a thick section casting.)X1.3 Pursuant to the above, a test specimen taken from a sacrificial casting and which produces test results that comply with therequirements of the applicable product standard should be considered as acceptable.SUMMARY OF CHANGESCommittee A01 has ident

28、ified the location of selected changes to this standard since the last issue(A1067/A1067M 10) 12) that may impact the use of this standard. (Approved May 1, 2012Nov. 1, 2012.)(1) Added Fig. 9 The minimum length of the coupon (Fig. 9and revised 6.2 accordingly.) was changed from 4 in. (100 mm) to5 in

29、. (125 mm), and the SI equivalent for the diameter from 130 to 125 mm.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard. Users of this standard are expressly advised that determination of the validity of a

30、ny such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years andif not revised, either reapproved or withdrawn. Your comments are

31、invited either for revision of this standard or for additional standardsand should be addressed to ASTM International Headquarters.

32、ved a fair hearing you shouldmake your views known to the ASTM Committee on Standards, at the address shown below.This standard is copyrighted by ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959,United States.
