5.1 The connection strength between geosynthetic reinforcement and segmental concrete block units is used in design of reinforced soil retaining walls.5.2 This test is used to determine the connection strength for the design of the connection system formed by segmental concrete block units and geosynthetic reinforcement layers in reinforced soil retaining walls. Performing a series of these connection tests at varying normal loads permits development of a relationship between connection strength and normal load. This relationship may be linear, bilinear, or some other complex mathematical expression.5.3 This connection strength test is meant to be a performance test (laboratory or field); therefore, it should be conducted using full-scale system components. The conditions for the test are selected by the user and are not for routine testing.5.4 As a performance test on full-scale system components, it accounts for some of the variables in construction procedures and materials tolerance normally present for these types of retaining wall systems.1.1 This test method is used to determine the connection properties between a layer of geosynthetic reinforcement and segmental concrete block units used in construction of reinforced soil retaining walls. The test is carried out under conditions determined by the user that reproduce the connection system at full scale. The results of a series of tests are used to define a relationship between connection strength for a segmental unit-geosynthetic connection system and normal load.1.2 This is a performance test used to determine properties for design of retaining wall systems utilizing segmental concrete units and soil reinforcing geosynthetics, either geotextiles or geogrids. The test is performed on a full-scale construction of the connection and may be run in a laboratory or the field.1.3 The values stated in SI units are regarded as the standard. The values stated in inch-pound units are provided for information only.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.

This test method covers the standard material criteria and test method for compression gaskets used in joining hub and spigot cast iron soil pipe and fittings for sanitary drain, waste, vent, and storm piping applications. The gaskets shall be made of a compound containing a thermoset elastomer and shall consist of one or more sealing ring(s) that compress to provide an airtight and watertight seal. Compression gaskets shall have an integral flange to prevent the gasket from rolling into the hub during installation and shall be designed to permit expansion, contraction, and deflection of assembled piping. The gaskets shall be restrained and subjected to hydrostatic pressure and the joint assembly performance shall be evaluated using the restrained hydrostatic joint testing apparatus wherein a water pressure gauge is used to ensure the accuracy of the test pressures.1.1 Several different types of compression gaskets are available for use in connection with hub and spigot cast iron soil pipe and fittings. The purpose of this test method is to establish material criteria and test procedures for compression gaskets used in joining hub and spigot cast iron soil pipe and fittings for sanitary drain, waste, vent, and storm drain piping applications in accordance with the general needs of producers, distributors, and users.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 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.1.4 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 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.

5.1 This practice is based on the use of electrical resistance as an indicator of contact performance.5.2 Existing standards, such as those referenced in Section 2 as representative examples, provide the basis for applied test conditions. Modifications in procedure or sample size, or both, of existing standards may have to be made to provide for resistance measurement and to meet variability index requirements that a user may specify.5.3 This practice accommodates the use of multiple test methods, as may be required to assure satisfactory performance in a given application.1.1 This practice provides a uniform method of specifying performance requirements for (or reporting test results of) electrical contact and connection systems. Both conductor and connector system performance may be specified by this practice, separately or in combination.1.2 This practice may be used for separable or permanent contacts employing metallic conductors and contacts.1.3 This practice provides methods for both signal and power applications.1.4 This practice does not specify the sample preparation or test sequences required for determining contact performance. It is the responsibility of the user of this practice to determine the applied test sequence(s) appropriate for the application.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 and health practices, and determine the applicability of regulatory limitations prior to use.
