Standard Specification for PVC Insulating Sheeting
This guide provides a recommended list of selected ship structure details for use in ship construction. Structural details which have failed in service and are not recommended for use in ship construction are included as well. This guide is intended to convey the lessons learned on different configurations of ship structure details, not the dimensions, thickness, or construction methods which would result from structural calculations. Details are shown for the ten families of structural details, which are: beam brackets, clearance cut-outs, gunwale connections, miscellaneous cut-outs, non-tight collars, panel stiffeners, stanchion ends, stiffener ends, tight collars, and tripping brackets. Evaluation of details is based on in-service experience as described in "Design Guide for Structural Details". Data for over 400 details is summarized and rated by observed relative successful performance. Each of the ten families of details includes configurations with no signs of failures. The details without failures within each family group are shown in descending order of numbers observed. Those details with failures are shown in ascending order of failures (percentages are indicated for each). Thus the first detail shown in each family group has the best observed service performance and is most highly recommended while the last has the highest failure rate and therefore least desirable. The details provide guidance in the selection of structural detail configurations in future design and repair of such details.
1.1 This specification covers acceptance testing of Poly Vinyl Chloride insulating sheeting for use as a covering for protection of workers.
1.2 The following safety hazards caveat applies only to the test method portion, Sections 17 – 19, 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.
1.3 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.
