Abstract:

This specification covers sampling and testing of laboratory glassware items for use until they are no longer considered functional for the intended purpose, and does not include disposable (single use) items. Four types of reusable laboratory glassware are covered, namely: blown and pressed glassware, nongraduated; blown and pressed glassware, graduated; tubular glassware, nongraduated; and tubular glassware, graduated. The product shall be designed to meet the specified test performance requirements. Alternate testing methods, inspection levels, and sample sizes may be implemented. Sampling shall be conducted in accordance with the specified inspection and examination levels and acceptance quality levels for major defects, minor defects, and dimensional examination. Where applicable, distilled water and reagent grade chemicals shall be used throughout the tests. Inspection shall be conducted in accordance with applicable section and individual specifications. The basic testing criteria for the following tests are detailed: (1) leakage test, (2) permanency of marking by alkali and acid tests, (3) capacity fill test, (4) autoclaving, (5) pour test, and (6) centrifugal test.
