This Standard outlines considerations and specifies procedures for taking undisturbed samples of soils for routine investigation purposes, and specifies a procedure for packing and forwarding the samples for examination and testing.Undisturbed samples taken in accordance with this Standard are generally suitable for strength, consolidation, reactivity and total suction tests. Classification, chemical, density and strength tests on remoulded specimens are normally performed on disturbed samples, sampled in accordance with AS 1289.1.2.1.Sampling of specimens for California Bearing Ratio tests on undisturbed samples is covered in AS 1289.6.1.2.The selection of the type of sampling device to be used, the technique to be applied and the location of sampling sites is not covered by this Standard. Random selection of sampling sites, when required, is covered by AS 1289.1.4.1 or AS 1289.1.4.2.NOTE: The sampling technique may be chosen according to the conditions, for there is no universal sampler suitable for all conditions. The three main factors to be considered are sampler type, sampler size and operating technique.
