5.1 The general design geometry herein defined applies to both a separate adaptor accessory mating two booms of different geometry as well as boom end connectors (see Terminology F818).5.2 Interconnectibility is intended to facilitate mating of oil spill response booms of various sizes, strengths, design, and manufacture.5.3 The use of this general design geometry in no way guarantees the effective performance of the linked boom sections, since each boom's design and the environmental conditions at each incident govern overall performance.AbstractThis specification covers design criteria requirements, design geometry, material characteristics, and desirable features for oil spill response boom connections. These criteria are intended to define minimum mating characteristics and are not intended to be restrictive to a specific configuration. Any material is acceptable for construction of the boom connector provided consideration is given to such factors as weight, mechanical strength, chemical resistance, flexibility, and conditions of the environment in which it is to be used. End connector and cross pin materials shall be corrosion resistant in sea water and such other environments as the intended service may require. If dissimilar metals are used, care shall be used in design to avoid galvanic corrosion. The minimum tensile strength of a boom-to-boom connection shall equal or exceed the minimum fabric tensile strength specified. When the connector is designed as an integral part of the boom, it shall ensure distribution or transfer of the tension member loads from one boom section to the next through or around the end connector in such a manner that the integrity of the joint is not broken. The connector shall be of the hook engagement design. The geometry of single hook engagement end connectors shall be compatible with the requirements specified. Desirable features of the connector design include the following: speed and ease of connection, light weight, connectable in the water, readily cleaned of sand and debris, inherently safe to personnel, and easy to install or replace.1.1 This specification covers design criteria requirements, design geometry, material characteristics, and desirable features for oil spill response boom connections. These criteria are intended to define minimum mating characteristics and are not intended to be restrictive to a specific configuration.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 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.

1.1 This test method provides a basic procedure for evaluating the tensile strength properties of the net section of finished metal connector plates. 1.2 This test method serves as a basis for determining the comparative performance of different types and sizes of metal connector plates in tension. 1.3 A companion test method, Test Method E767, covers the performances tests on these plates in shear. 1.4 Method D1761 covers the performance of the teeth and nails in wood members during the use of metal connector plates (see Note 1). Note 1-The maximum design load in tension, an indication of the effectiveness of the net cross section of the perforated metal connector plate, is not necessarily a criterion of the effectiveness of the plate in transmitting the load from wood member to wood member, since that property is influenced by a number of factors, including the effectiveness of the nails or that of the integral plate projections, or a combination thereof, used in the wood species under consideration, and tested in accordance with Method D1761. 1.5 This test method does not provide for the corrosion testing of metal connector plates exposed to long-term adverse environmental conditions where plate deterioration occurs as a result of exposure. Under such conditions, special provisions shall be introduced for the testing for corrosion resistance. 1.6 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 The general design geometry herein defined applies to both a separate adaptor accessory mating two booms of different geometry as well as boom end connectors (see Terminology F818).5.2 Interconnectibility is intended to facilitate mating of oil spill response booms of various sizes, strengths, design, and manufacture.5.3 The use of this general design geometry in no way guarantees the effective performance of the linked boom sections, since each boom’s design and the environmental conditions at each incident govern overall performance.1.1 This specification covers design criteria requirements, design geometry, material characteristics, and desirable features for oil spill response boom slide connections. These criteria are intended to define minimum mating characteristics and are not intended to be restricted to a specific configuration.1.2 The specification defines the geometry required to mate with typical Universal slide connectors or Specification F962 connectors with web thickness up to 0.3 in. Some very heavy-duty or PVC connectors may exceed this dimension and not be compatible.1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this 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.

4.1 Materials for electrical connector contacts must satisfy a number of requirements in the areas of electrical, mechanical, and economic characteristics. The stability of electrical properties is one of the most important of these characteristics. Wear of contact surfaces may adversely affect these electrical properties, especially in designs where the contact surfaces are relatively thin coatings. This test method provides a means to compare various material systems on a basis relevant to their application in electrical connector contacts.4.2 Repeated insertion and withdrawal of a connector may cause wear or other mechanical damage to the electrical contact surfaces, rendering those surfaces more susceptible to environmental degradation. This test method is intended to detect degradation of the electrical properties of the connector by such processes.4.3 This test method describes procedures for conducting wear and durability testing of electrical connectors; the procedures produce quantitative results. These results may be used to compare the performance of different connector designs so that meaningful design choices can be made. Such results may also be used to compare the performance of a connector to a previously established standard to evaluate the quality of the samples under test.4.4 The test results obtained from this test method are limited in their applicability to connector combinations that are equivalent in design and manufacture to those actually tested.4.5 The user is cautioned that the conditions in this test should be compared to the conditions that the connector will experience in the intended application in order to determine the relevance of this test method to the particular needs of the user. For example, the environmental stress in this test method is less severe than certain industrial and marine environments and therefore test results are not directly applicable to predict the performance of product intended for use in such areas.4.6 It is recommended that this test method be used in one of two ways. First, it may be used to evaluate and report the performance of a particular connector system. In such a case, it is appropriate to report the results in a table in the format shown in Fig. 1 and to state “The results shown in the table were obtained for (insert connector designation or description) when tested in accordance with ASTM Standard B794, Method __ , Procedure __ .” Second, it may be used to impose requirements for acceptance of product. In this case, limits for the values shown in Fig. 1 must be established prior to product acceptance testing. Such limits may be established by various methods such as by evaluation of product which is known to be acceptable or by application of appropriate experience. These limits must be documented in a manner that the entity performing the product test can refer to the limits to determine if the test product conforms to such limits. A purchaser may wish to supply a table of limits and include on the purchase order a statement similar to: “The product, when tested in accordance with ASTM Standard B794, Method __ , Procedure __ , shall meet the limits in the supplied table.” This table supplied by the purchaser may set limits on all of the values in Fig. 1, or only on a subset of those values that the purchaser deems adequate to ensure the performance of the product.FIG. 1 Sample Format for Reporting Results1.1 This test method covers the effects of repeated insertion and withdrawal of separable electrical connectors which are harmful to the electrical performance of the connector.1.2 This test method is limited to electrical connectors designed for use in applications where the current through any one connection in the connector does not exceed 5 A, and where the connector may be separated a number of times during the life of the connector.1.3 This test method is limited to electrical connectors intended for use in air ambients where the operating temperature is less than 65°C.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 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 become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.1.6 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.
