The concentration in micrograms per liter (g/L) will equal the parts per billion (ppb). When specific gravity is not
14、 equal to unity, mg/L or g/L divided by the specific gravity of the solution will equal ppm or ppb, respectively. 2Test measurements conducted in accordance with the indicated test standards are expressed in g/L and should be converted to the mg/L equivalent using 1 mg/L = 1000 g/L. 4. QUALITY ASSUR
15、ANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the acquisition order (see 6.2), the contractor is responsible for the performance of all inspection requirements (examinations and tests) specified herein. Except as otherwise specified in the acquisition order (see 6.
16、2), the contractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in this specification where such inspections ar
17、e deemed necessary to ensure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items supplied to the Government shall meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors over
18、all inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the government for acceptance comply with all requirements of the contract. Sampling
19、 inspection, as part of the manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.1.2 Contrac
20、tor assurance of compliance. The contractors quality program or detailed inspection system shall provide assurance of compliance of all characteristics with the applicable drawing and specification requirements using, as a minimum, the conformance criteria specified herein. 4.1.3 Alternative inspect
21、ion provisions. When specified in the acquisition order (see 6.2), alternative inspection provisions, methods, or equipment such as statistical process control, tool control, and other types of sampling procedures may be used by the contractor when they provide, as a minimum, the level of quality as
22、surance required by the inspection provisions specified herein. Prior to applying such alternative procedures, methods, or equipment, the contractor shall describe them in a written proposal submitted to the Government for evaluation and approval. The contractor shall demonstrate that the effectiven
23、ess of each proposed alternative is equal to or better than the quality assurance provisions specified herein. In cases of dispute as to whether the contractors proposed alternative provides equal quality assurance, the provisions of this Provided by IHSNot for ResaleNo reproduction or networking pe
24、rmitted without license from IHS-,-,-O-B-41H 4 specification shall apply. All approved alternative inspection provisions shall be specifically incorporated into the contractors quality program or detailed inspection system, as applicable. 4.2 Quality conformance inspection. 4.2.1 Lot. A lot shall co
25、nsist of the battery water produced by one manufacturer at one plant from the same materials and under essentially the same manufacturing conditions, provided the operation is continuous. In the event the process is a batch operation, each batch shall constitute a lot (see 6.3.1). 4.2.2 Sampling for
26、 battery water tests. Sampling shall be conducted in accordance with table II. A representative specimen of approximately 0.9 liter (L) shall be removed from each sample container and placed in a suitable clean, dry container labeled to identify the lot and container from which it was taken. TABLE I
27、I. Sampling for battery water tests. Number of containers in a batch or lot Number of samples 1 to 2 Sample 100% 3 to 25 2 26 to 150 3 151 to 1,200 5 1,201 to 7,000 8 7,001 to 20,000 10 over 20,000 20 4.2.3 Inspection procedures for battery water tests. Each sample specimen taken in accordance with
28、4.2.2 shall be tested as specified in 4.3.1. Failure of any test by any inspection shall be cause for rejection of the lot represented. 4.3 Test methods. 4.3.1 Battery water tests. Reagent-grade water meeting the requirements of ASTM D1193 and reagent-grade chemicals shall be used throughout the tes
29、ts. Where applicable, blank determinations shall be run and corrections applied where significant. Unless otherwise specified (see 6.2), acid and base reagents shall be concentrated acids and bases. Tests shall be conducted as specified in 4.3.1.1 through 4.3.1.10. 4.3.1.1 Physical characteristics t
