1.1 This practice establishes minimum qualifications for agencies engaged in the testing and inspection ofsoil and rock.Minimum requirements for field and laboratory personnel are defined. The practice also covers the establishment and main-tenance of a quality system.

1.1 These test methods cover rubber identification and are based on infrared examination of pyrolysis products (pyrolyz-ates) and films. 1.2 These test methods are applicable to rubbers in the raw state and, when compounded, both in the cured and uncured state.

1.1 This test method covers the measurement of soluble,suspended, and total 226 Ra in water in concentrations above 3.7 × 10 −3 Bq/L. This test method is not applicable to the measurement of other radium isotopes. 1.2 This test method may be used for quantitative measure-ments by calibrating with a 226 Ra standard, or for

1.1 This test method covers the determination of total acidity in trichlorotrifluoroethane and other halocarbons that are liquid at room temperature. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.1 These test methods cover procedures for the analysis of white zinc pigments.

1.1 This specification covers machine-made fiberglass pipe,8 in. (200 mm) through 156 in. (4000 mm), intended for use in gravity-flow systems for conveying sanitary sewage, storm water, and some industrial wastes. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipes. NOTE 1—For the purposes of this standard, polymer does not

1.1 This practice describes a procedure for establishing tolerances and evaluating the color and gloss of specimens with respect to specified standards.This practice is appropriate for nonfluorescent opaque specimens. 1.2 This practice does not indicate the extent of tolerances,but gives guidance on how they can be set.For product specification,the tolerances between specimens and the speci-fied

1.1 This test method covers the determination of sulfur concentration in the range from 3.0 mg ⁄kg to 1000 mg ⁄kg in light liquid hydrocarbons and fuels with oxygenates boiling in the range from 26 °C to 274 °C (80 °F to 525 °F). NOTE 1—Preliminary data has shown that this test method is also
