1. The review of the efficiency and effectiveness of the current test methods as a demonstration of the effectiveness of the sealant solution.
2. The research and review of alternative test methodologies to demonstrate the effectiveness of sealant solutions
3. Recommendations for the performance requirements for each test method; and
4. The development of one new LC suite GIS (referred to throughout as the “Private Standard”) for gas leakage sealants. It will be a performance specification producedas a result of the review, re-categorization and amalgamation of the following sixexisting LC suite of GISs.

The standards being considered as part of this project are as follows:

• GIS/LC8 Part 1 - Specification for methods of repairing leaking ferrous gas mains. Part 1 - External systems (excluding joint and pipe clamps)
• GIS/LC8 Part 3 - Specification for methods of repairing leaking ferrous gas mains. Part 3 - Internal sealing methods
• GIS/LC9 - Specification for methods of repairing joints on screwed pipework
• GIS/LC12 - Specification For External Sealant Injection Systems For Joint Repair On Ferrous Distribution Mains Systems Operating At Pressures Equal To Or Less Than 2 Bar
• GIS/LC14 - Specification for annular gap sealants
• GIS/LC25 - Specification For External Sealant Injection Systems For Joint Repair On Ferrous Distribution Mains Systems Operating At Pressures Equal To Or Less Than 2 Bar Performance Specification

To develop and deliver a new combined standard utilising new or alternative test methodologies to allow for the cost effective assessment and implementation of leakage sealants across all UK gas distribution networks.
