ASTM A1067 A1067M-2012 Standard Specification for Test Coupons for Steel Castings《钢铸件试样标准规格》.pdf

1、Designation: A1067 10 A1067/A1067M 12Standard Specification forTest Coupons for Steel Castings1This standard is issued under the fixed designation A1067;A1067/A1067M; the number immediately following the designation indicatesthe year of original adoption or, in the case of revision, the year of last

2、 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 standardspecification defines the geometries of several separately-cast and integrally-cast test coupons for use ass

3、pecified in the applicable casting product or common requirements standard. This standard does not address procedures formolding, casting, heat treating, machining, or testing; these items are addressed as needed and appropriate by the applicableproduct or common requirements standard.NOTE 1The test

4、 coupons 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 u

5、nits are 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 ad

6、dress 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

7、 standard 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

8、same heat, 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 o

9、f the 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

10、 feeder 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 stat

11、edrequirements, 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 sh

12、own in this standard are not necessarily drawn to scale. The values shown in the tables constitute thedimensional requirements.1 This specification is under the jurisdiction of ASTM Committee A01 on Steel, Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.18on C

DOI: 10.1520/A1067_A1067M-12.This document is not an ASTM standard and is intended only to provide the user of an ASTM standa

14、rd an indication of what changes have been made to the previous version. Becauseit may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current versionof the standard as published by ASTM

16、ons (Figs. 1-89). Other designs may besuitable when shown to produce acceptable properties or where agreed.7. Workmanship, Finish, and Appearance7.1 Care should be taken in the preparation and pouring of the molds to avoid the creation of inclusions or other anomalies inthe resulting test specimens.

17、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.9. Number of Tests and Retests9.1 Sufficient test coupons shall be produced to provide the needed number of test specimens.Feature 4leg d

MOLD MATERIALX1.1 A test coupon is used to demonstrate that the met

25、al can obtain the specified minimum properties, not that the casting hascertain 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 t

26、he coupons are used to demonstrate the capability of the metal, any design 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 prov

27、ide improved properties in some instances.) Conversely, test coupons may be 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 al

28、loys. (This isrelated to the chilling issue; a thin section test coupon cools 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 sh

29、ould be considered as acceptable.SUMMARY OF CHANGESThese test coupons were previously defined in multiple other standards. Committee A01 has identified thelocationslocation of selected changes to these test coupon definitions this standard since the last issue(A1067/A1067M 10) that may impact the us
