specification shall apply. All approved alternative inspection provisions shall be specifically incorporated into the contractor's quality program or detailed inspection system, as applicable.
4.2 Quality conformance inspection.
4.2.1 Lot. A lot shall consist 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 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.

4.2.3 Inspection procedures for battery water tests. Each sample specimen taken in accordance with 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 tests. 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 test. Pour approximately 50 milliliters (mL) of the well-mixed specimen into a clean, dry, 25 x 150 mm test tube. Immediately examine for odor and then allow to stand for not less than 10 minutes. Examine by transmittance light for clarity, color,
suspended matter, and sediment.
4.3.1.2 Total solids and organic and volatile matter. Determine the total solids and organic and volatile matter content of the specimen in accordance with ASTM D6317.
