4.1 This guide defines a series of test methods to determine the oil containment effectiveness of containment booms when they are subjected to a variety of towing and wave conditions. The test methods measure the tow speed at which the boom first loses oil (both in calm water and in various wave conditions), the tow speed at which the boom reaches a gross oil loss condition (both in calm water and in various wave conditions), boom conformance to the surface wave conditions for various wave heights, wavelengths and frequencies, (qualitatively), resulting tow forces when encountering various speeds and wave conditions, identifies towing ability at high speeds in calm water and waves, boom sea-worthiness relative to its hardware (that is, connectors, ballast members), and general durability.4.2 Users of this guide are cautioned that the ratio of boom draft to tank depth can affect test results, in particular the tow loads (see Appendix X1 discussion).4.3 Other variables such as ease of repair and deployment, required operator training, operator fatigue, and transportability also affect performance in an actual spill but are not measured in this guide. These variables should be considered along with the test data when making comparisons or evaluations of containment booms.1.1 This guide covers the evaluation of the effectiveness of full-scale oil spill containment booms in a controlled test facility.1.2 This guide involves the use of specific test oils that may be considered hazardous materials. It is the responsibility of the user of this guide to procure and abide by the necessary permits for disposal of the used test oil.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.4 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.1.5 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.

5.1 Upon mutual agreement between the purchaser and the seller, fabrics intended for this end use should meet all of the requirements listed in Table 1 of this specification.5.2 It is recognized that for purposes of fashion or aesthetics the ultimate consumer of articles made from these fabrics may find acceptable fabrics that do not conform to all of the requirements in Table 1. Therefore, one or more of the requirements listed in Table 1 may be modified by mutual agreement between the purchaser and the seller.5.2.1 In such cases, any references to the specification shall specify that: “This fabric meets ASTM Specification D3995 except for the following characteristic(s).”5.3 Where no pre-purchase agreement has been reached between the purchaser and the seller, and in case of controversy, the requirements listed in Table 1 are intended to be used as a guide only. As noted in 5.2, ultimate consumer demands dictate varying performance parameters for any particular style of fabric.5.4 The significance and use of particular properties and test methods are discussed in the appropriate sections of the specified test methods.1.1 This performance specification covers the minimum performance requirements for knitted fabrics for dress and vocational career apparel composed of any textile fiber or mixtures of textile fibers.1.2 This performance specification is not applicable to career apparel fabrics such as those used in protective clothing, that do not patently fit the categories Career Apparel or Career Apparel, Dress (see Terminology D7022 for these terms). Minimum performance specifications for such fabrics should be as agreed between the purchaser and the seller.1.3 These requirements apply to the length and width directions for those factors where each fabric direction is pertinent.1.4 The following precautionary statement pertains only to the test methods portion, Section 7, of this specification. 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.1.5 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.
