Sampling for Chemical Analysis10.1 SamplesTen ingots shall constitute a representativesample of any shipment lot up to

11、50 000 lb (18 700 kg) orfraction thereof. When a shipment exceeds 50 000 lb, anadditional ingot shall be added for each additional 5000 lb(1870 kg) or fraction thereof. In the case of shipment lots of teningots or less, each ingot shall be drilled once to provide asufficient sample for analysis.1Thi

United States110.2 DrillingThe ingots shall be sampled by drillingthrough with a drill12 in. (2.7 mm) in diameter, in accordancewith Practice E88. The drill shall be cleaned thoroughly befo

15、reuse, and no lubricant shall be used in drilling. Each sampleingot shall be drilled through once from top to bottom. One ofthree ingots shall be drilled centrally, while the other two shallbe drilled midway between the center and a corner of thebottom. The drillings shall be made fine, and stray la

16、rge chipsor chunks created in starting a hole shall be discarded. Thedrillings shall be gone over with a powerful magnet to removeany iron introduced by sampling. The drilling shall be mixedthoroughly.11. Methods of Chemical Analysis11.1 The chemical composition enumerated in Table 1 ofthis specific

17、ation shall, in case of disagreement, be determinedby wet chemical or spectrographic methods mutually agreedupon between the supplier and the purchaser.11.2 By agreement between the purchaser and the supplier,analyses may be required and limits established for elements orcompounds not specified in T

Rejection and Rehearing13.1 Material that fails to conform to the requirements ofthis specification shall be rejected. Rejection should be re-ported t

19、o the supplier promptly and in writing. In case ofdissatisfaction with the results of the test, the supplier maymake claim for a rehearing.13.2 Rejection shall be considered as follows:13.2.1 Variation of weight, quantity, or workmanship, or13.2.2 Chemical composition.13.2.2.1 In case of dispute, th

20、e material shall be sampled inthe presence of both parties in accordance with Section 10.13.2.2.2 The resulting sample shall be mixed and separatedinto three equal parts, each of which shall be placed in a sealedpackage, one for the supplier, one for the purchaser, and one foran umpire, if necessary

21、. The manufacturer and the purchasereach shall make an analysis, and if the results do not establishor dismiss the claim to the satisfaction of both parties, thesample shall be submitted to a mutually agreed-upon umpire.The umpire shall determine the question of fact using ananalytical method agreed

22、 upon by both parties; the umpiresdetermination shall be final.13.3 Where the antimony meets the requirements of thesespecifications as to chemical composition, it shall not becondemned for defects in manufacturing or for defects in theproducts or alloys in which it is used.14. Certification14.1 Whe
