2、evision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This test method establishes the requireme

3、nts for theexpansion pin test for copper and copper-alloy pipe and tubingwith an inside diameter of 0.125 in. (3.2 mm) and greater or anoutside diameter up to and including 4 in. (102 mm).NOTE 1For tubes of sizes with an inside diameter less than 0.125 in.(3.2 mm), a substitute test method must be a

4、greed upon between themanufacturer and purchaser.NOTE 2For tubes of sizes greater than 4 in. (102 mm) in outsidediameter, refer to B968/B968M for a test method.1.2 UnitsThe values stated in inch-pound units are to beregarded as standard. The values given in parentheses aremathematical conversions to

5、 SI units that are provided forinformation only and are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and det

Terminology3.1 For definitions of terms related to copper and coppe

7、ralloys, refer to Terminology B846.4. Summary of Test Method4.1 The prepared test specimen is expanded over a conicalpin inserted at a uniform speed or pressure. The expansion ofthe test specimen shall be measured on the outside of the tubediameter and shall conform to the product specification.5. S

8、ignificance and Use5.1 When properly performed and interpreted, the expan-sion pin test will provide information with regard to thecapacity of a tube for expansion and to reveal surface defects.The expansion pin test may provide data for research anddevelopment, engineering design, quality control,

9、and accep-tance or rejections in specifications.5.2 In certain product specifications which establish require-ments for tubes of sizes greater than 4 in. (102 mm), the testdescribed in B968/B968M may be allowed as a substitute.6. Apparatus6.1 PinThe conical pin shall have an included angle of60, unl

10、ess provided otherwise in the product specification.The pin shall be made of carbide or tool steel that has beenhardened and ground to the prescribed angle and shall have asmooth, polished surface. The size of the pin at the base shallbe suitable for the size of tubing being tested.6.2 Testing Machi

11、neAny type of testing machine, eitherhydraulically or mechanically operated, that will exert pressureto expand the pipe and tubing on the pin at a uniform rate.7. Sampling and Test Specimen Preparation7.1 The test specimen shall be prescribed in the specifica-tion for the product being tested. In th

12、e event that a testspecimen size is not prescribed in the pipe or tube specifica-tion, the specimen shall be of suitable length so that it can beexpanded to the required amount. Both ends shall either befaced square to the longitudinal axis in a lathe, or suitablyprepared so as to have a smooth surf

13、ace free from scratches orburrs, which might interfere with the test.1This test method is under the jurisdiction of ASTM Committee B05 on Copperand Copper Alloys and is the direct responsibility of Subcommittee B05.06 onMethods of Test.Current edition approved Jan. 1, 2011.

Procedure8.1 The test specimen shall be wiped clean to remove anyloose chips

16、or dirt from the inside surface. The specimen shallbe well lubricated (Note 3) on the inside surface. The pin (6.1)for use in the test, as prescribed in the specifications for theproduct being tested, shall be wiped clean and free from dirt,grit, or chips, and coated with lubricant.NOTE 3No. 1 lard

17、oil or any extreme pressure lubricating oil isrecommended as a lubricant.8.2 The test specimen shall be expanded over the pin to theamount prescribed in the specification. During the expansionthe testing machine shall be operated at a uniform speed orpressure. The longitudinal axes of the test speci

18、men and the pinshall coincide. The expanded tube shall be examined with theunaided eye to determine conformance with the productspecification. Expansion shall be measured on the outsidediameter of the tube.8.2.1 Subject to agreement by the manufacturer and thepurchaser, the test specimen may be expa

19、nded by hand-hammering or by manually or mechanically pressing the pin,except that in case of dispute another test specimen shall beexpanded as described in 8.2.8.3 In case there is an indication that the specimen was notproperly prepared or tested, a new specimen from the samesample shall be select

20、ed and tested.8.4 During inspection, the expanded section of the testspecimen shall be free of defects, but blemishes of a nature thatdo not interfere with the intended application are acceptable.9. Retests9.1 In case of failure of any specimen a retest shall beallowed in accordance with the require

21、ments of the productspecification.10. Report10.1 When testing is completed by an independent third-party laboratory, the test report shall include the followinginformation. In-house captive laboratories shall only report10.1.1, 10.1.2 and 10.1.5.10.1.1 The date of the test,10.1.2 Sample identificati

22、on,10.1.3 Reference to the test method,10.1.4 The number of replicate test pieces used,10.1.5 The test results: Pass or Fail (relative to presence ofdefects) as required above and by the appropriate productspecification, and10.1.6 Any other features of the material noted during theinspection.11. Pre

23、cision and Bias11.1 No statement is made about either the precision or biasof this test method since the result merely states whether thereis conformance to the acceptance criteria specified in theprocedure and the product specification.12.
