1、Designation: B 153 05Standard Test Method forExpansion (Pin Test) of Copper and Copper-Alloy Pipe andTubing1This standard is issued under the fixed designation B 153; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、 revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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 requir
3、ements 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 b
4、e agreed upon between themanufacturer and purchaser.NOTE 2For tubes of sizes greater than 4 in. (102 mm) in outsidediameter, a test method must be agreed upon between the manufacturerand purchaser. The flattening test, as described in the various pipe and tubespecifications, is recommended as a subs
5、titute for the expansion pin test.1.2 UnitsThe values stated in inch-pound units are re-garded as standard. The values given in parentheses aremathematical conversions to SI units that are provided forinformation purposes only and are not considered standard.1.3 This standard does not purport to add
6、ress 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 determine the applica-bility of regulatory limitations prior to use.2.

7、logy Relating to Copper and Copper Alloys3. Terminology3.1 For definitions of terms related to copper and copperalloys, refer to Terminology B 846.4. 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 s
8、pecimen shall be measured on the outside of the tubediameter and shall conform to the product specification.5. Significance 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 de
9、fects.Expansion pin test may provide data for research and devel-opment, engineering design, quality control, and acceptance orrejections in specifications.6. Apparatus6.1 PinThe conical pin shall have an included angle of60, unless provided otherwise in the product specification.The pin shall be ma
10、de 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 MachineAny type of testing machine, eitherhydraulically or mechanically oper
11、ated, 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 material being tested. In the event that a testspecimen size is not prescribed in the pipe or tube
12、 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 surface free from scratches orburrs, which might interfere with the test.8
13、. Procedure8.1 The test specimen shall be wiped clean to remove anyloose chips 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 thematerial being tested, shall be wiped clea
14、n and free from dirt,grit, or chips, and coated with lubricant.NOTE 3No. 1 lard oil or any extreme pressure lubricating oil isrecommended as a lubricant.1This test method is under the jurisdiction of ASTM Committee B05 on Copperand Copper Alloys and is the direct responsibility of Subcommittee B05.0

17、est 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 specimen and the pinshall coincide. The expanded tube shall be examined with theunaided
18、 eye to determine conformance with the productspecification. Expansion shall be measured on the outsidediameter of the tube.8.3 Subject to agreement by the manufacturer and thepurchaser, the test specimen may be expanded by hand-hammering or by manually or mechanically pressing the pin,except that i
19、n case of dispute another test specimen shall beexpanded as described in 8.2.8.4 In case there is an indication that the specimen was notproperly prepared or tested, a new specimen from the samesample shall be selected and tested.9. Retests9.1 In case of failure of any specimen a retest shall beallo
20、wed in accordance with the requirements of the specifica-tion.10. Precision and Bias10.1 No statement is made about either the precision or biasof this test method since the result merely states whether thereis conformance to the criteria for success specified in theprocedure.11.
