13.Sampling
13.1Sampling —Four test specimens shall be obtained,one from each of four production units (Explanatory Note 1)or in accordance with the statistical sampling methods as prescribed by Specification B 830.
14.Test Methods
14.1Diameter —Measure the diameter of each specimen with a micrometer caliper graduated in 0.0001-in.increments or measure the diameter of each specimen with a micrometer caliper graduated in minimum 0.005mm increments for wires less than 1.00mm in diameter,or minimum 0.01-mm incre-ments for wires 1.00mm in diameter and larger.Take two measurements at one point,with the cond measurement across the cross-ctional diameter 90°rotated from the first measurement.Average the two measurements to obtain the specimen diameter.Should the measured diameter of any specimen vary from the specified diameter by an amount greater than the
tolerance permitted by Table 4,the lot shall be considered to not meet diameter requirements.
14.2Finish —Make a visual surface finish inspection with the unaided eye (corrective lens excepted).The surface finish shall meet the requirements of 6.1.Should any specimen be found unacceptable,the lot shall be considered to not meet surface finish requirements.
14.3Tensile strength and elongation may be determined simultaneously.Obtain the tensile strength,in accordance with Test Methods B 557or B 557M ,by dividing the maximum load resisted by the tensile specimen by the original cross-ctional area of the specimen,with the tensile stress to be expresd in ksi [MPa].Elongation is the percent increa in length of the tensile test specimen as measured between gage marks originally spaced 10in.[250mm]apart on the speci-men.Elongation measurements are not required for wires <0.0500in.[<1.25mm]in diameter.Should any part of the fracture take place outside the elongation gage lines,or if examination of the tensile specimen indicates a flaw,the values obtained may not be reprentative and a test on another ction of the specimen may be run (Explanatory Note 6).14.4Determine the electrical resistivity in accordance with Test Method B 193.
14.5Test Results —A numerical average for the tensile strength,elongation,and resistivity of the four specimens shall be calculated and shall be considered the lot average.
14.6Conformance Criteria —To be considered in conform-ance,the lot average test results shall meet the average for a lot requirements of Table 1or Table 2and Table 3,and the test results of each specimen shall meet the individual tests requirements of Table 1or Table 2and Table 3unless otherwi specified.
14.6.1If the lot average results are in conformance,and all of the individual specimen results are in conformance,the lot shall be considered in conformance.
14.6.2If the lot average result for one or more of the tested properties is not in conformance and one or more of the individual specimen results is also not in conformance,the lot shall be considered not in conformance.
14.6.3If the lot average results are in conformance,but one or more of the individual specimen results are not in conform-ance,the lot shall be considered in conformance except that the production unit or units reprented by the non-conforming specimen or specimens shall be rejected.
14.6.4If the lot average results for one or more of the tested properties is not in conformance,but all the individual speci-men results are in conformance,then additional test specimens and tests shall b
e required as follows:
14.6.4.1An additional six test specimens shall be obtained,one each from six production units other than the four originally sampled.Tests shall be run on the six additional specimens,and a numerical average of the ten tested specimens shall be calculated and considered the lot average.
14.6.4.2If the ten specimen lot average results are in conformance,and all ten of the individual specimen results are in conformance,the lot shall be considered in conformance.14.6.4.3If the ten specimen lot average results for one or more of the tested properties are not in conformance,or if one or more of the ten individual specimen results are not in conformance,the lot shall be considered not in conformance.14.6.5In the event a lot is rejected in accordance with 14.6.2or 14.6.4.3,production units making up that lot may be individually tested.Acceptance of individual production units from a rejected lot shall be dependent on the individual specimen test results meeting the average for a lot requirements of Table 1or Table 2and Table 3.
14.7Bending (Brittleness)—Specimens from any produc-tion unit may be tested,with the frequency of sampling and testing to be agreed upon by the manufacturer and the purchar.
15.Inspection
15.1Unless otherwi specified in the purcha contract,the manufacturer shall be responsible for the performance of all inspection and testing requirements specified.
15.2All tests and inspections shall be made at the place of manufacture unless otherwi agreed upon by the manufacturer and the purchar.

EXPLANATORY NOTES
N OTE 1—A lot should compri material taken from a product regularly meeting the requirements of this specification.Inspection of lots of less than 5000lb [2500kg]of wire cannot be justified economically.For small lots of less than 5000lb [2500kg]the purchar may agree to the manufacturer’s regular inspection of the product as a whole as evidence of acceptability of such sma
ll lots.
N OTE 2—Evidence of statistical control must be demonstrated.To do this,control charts,as described in Part 3of ASTM STP 15D 5may be ud.N OTE 3—The speed of testing can affect the results of the tensile strength and elongation test.In order to ensure uniformity in the test method and valid applicability of the test results to the conformance criteria,it is recommended that the rate of paration of the heads of the tensile test machine not exceed 0.5in.for each inch or 0.5mm for each millimetre of length between grips per minute.
N OTE 4—Relationships that may be uful in connection with the values of electrical resistivity are shown in Table 3.Resistivity units are bad on the International Annealed Copper Standard (IACS)adopted by IEC in 1913,which is 1⁄58V ·mm 2/m at 20°C (68°F)for 100%conduc-
tivity.The value of 0.017241V ·mm 2/m at 20°C (68°F)is the international equivalent of volume resistivity of annealed copper equal to 100%conductivity.A complete discussion of this subject is contained in NBS Handbook 100.The u of five significant figures in expressing resistivity does not imply the need for greater accuracy of measurement than that specified in Test Method B 193.The u of five significant figures is required for reasonably accurate reversible conversion from one t
of resistivity units to another.The equivalent resistivity values in Table 3were derived from the fundamental IEC value (1⁄58V ·mm 2/m)computed to ven significant figures and then rounded to five significant figures.N OTE 5—Cumulative historic results cured on the product of a single manufacturer indicating a record of continual conformance of that product with the requirements of this specification are necessary to ensure that the sample can be assumed reprentative of the lot,and that the conformance criteria will largely ensure compliance of the lot with this specification.The sample sizes and conformance criteria are applicable only to lots produced by manufacturers that meet this requirement.
N OTE 6—Elongation measurements made and reported by the test apparatus may be ud for process control purpos.However,in ca of a discrepancy,measurements shall be made on a 10in.[250mm]specimen as stated above.
