This specification designates woods to be used as panels in weathering tests of coatings such as solvent-borne or water-borne paints. Different wood species shall be considered for testing due to their wide variations in the anatomy and density. Wood species materials for test panels include western red cedar, white pine and Ponderosa pine, southern pine, redwood, and Douglas fir. Wood panel characteristics such as weight per volume, wood character, panel thickness, surface smoothness, relative humidity, and growth rings density shall be in accordance with the specification.1.1 This specification designates woods for weathering tests of exterior solvent-borne or water-borne paints and other materials of similar purpose. Such tests may include either outdoor exposure tests or accelerated laboratory tests. It is the purpose of this specification to minimize the influence of variation of wood of a given species on test results.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

4.1 The field examination, sampling, and petrographic examination in this practice along with appropriate laboratory testing may be used to determine the suitability of rock for erosion control. Factors to consider include identification and delineation of areas or zones of the rock, beds, and facies of unsuitable or marginal composition and properties due to weathering, alteration, structural weaknesses, porosity, and other potentially deleterious characteristics.4.2 Evaluate both the rock mass properties and the rock material properties.4.2.1 The rock mass properties are the lithologic properties of the in situ rock that are evaluated on a macroscopic scale in the field. These properties include features such as fractures, joints, faults, bedding, schistosity, and lineations, as well as the lateral and vertical extent of the rock unit.4.2.2 The rock material properties are those lithologic properties that may be evaluated using small specimens and thus can be subject to meaningful laboratory testing. These properties would include mineral composition, grain size, rock hardness, degree of weathering, porosity, unit weight, and many others.4.3 Rock proposed for use in erosion control applications are normally classified as either filter bedding stone, riprap stone, armor stone, or breakwater stone. However, these procedures may be also extended to rocks used in groin and gabion structures.4.4 In cases in which only stockpile samples are to be obtained for laboratory testing, a full quarry geological examination may not be required. It is the responsibility of the specifier of this standard to indicate which sections of this Practice apply to the specific project.NOTE 2: The quality of the result produced by this standard is dependent upon the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluation some of those factors.1.1 This practice covers the evaluation of rock to be used for erosion control. The complexity and extent of this evaluation will be governed by the size and design requirements of the individual project, the quantity and quality of rock required, and the potential risk for property damage or loss of human life.1.2 It is not intended that all of the evaluations listed in this practice be addressed for every project. For some small, less critical jobs, a visual inspection of the rock may be all that is necessary. Several of the evaluations listed may be necessary on large, complex, high-hazard projects. It is the responsibility of the designer to determine the intensity and number of evaluations made on any one project.1.3 Examination of the rock at the source, evaluation of similar rock exposed to the environment at any field installations, as well as laboratory tests may be necessary to determine the properties of the rock as related to its predicted performance at the site of intended use (1, 2, 3, 4, 5, 6).21.4 The examination of the rock at its source is essential to its evaluation for erosion control and aids in the planning of the subsequent laboratory examinations. Very large pieces of rock up to several tons weight are used in the control of erosion; take great care with the field descriptions and in the sampling program to assure that zones of impurities or weaknesses that might not occur in ordinary size specimens are recorded and evaluated for their deleterious potential under the conditions of intended use. It is necessary that the intended method of rock removal be studied to ascertain whether the samples taken will correspond to the blasting, handling, and weathering history of the rock that will finally be used (3).1.5 The specific procedures employed in the laboratory examinations depend on the kind of rock, its characteristics, mineral components, macro and micro structure, and perhaps most importantly, the intended use, size of the pieces, and the exposure conditions at the site of use (1, 2, 3, 4).1.6 It is assumed that this practice will be used by personnel who are qualified by education and experience to plan the necessary evaluations and to conduct them so that the necessary parameters of the subject rock will be defined. Therefore, this practice does not attempt to detail the laboratory techniques required, but rather to mention them and only detail those properties that are of special concern in the course of the examination for rock to be used for erosion control.1.7 Units—The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are provided for information only.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.NOTE 1: Erosion stone pieces can weigh from several hundred pounds to several tons. Exercise caution at all times as the mass of each piece represents a potential pinch point and a lifting, handling, and carrying hazard.1.9 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
