Tähtaeg 16.03.2018
Plastics piping systems for renovation of underground gas supply networks - Part 1: General (ISO/DIS 11299-1:2018)
This document specifies the requirements and test methods for plastics piping systems intended to be used for the renovation of underground gas supply networks. It is applicable to pipes and fittings, as manufactured, as well as to the installed lining system. It is not applicable to the existing pipeline or any non-structural sprayed coatings or annular filler. This document gives the general requirements common to all relevant renovation techniques.

Tähtaeg 16.03.2018
Plastics piping systems for renovation of underground gas supply networks - Part 3: Lining with close-fit pipes (ISO/DIS 11299-3:2018)
This part of ISO 11299, in conjunction with ISO 11299-1, specifies requirements and test methods for close-fit lining systems intended to be used for the renovation of gas supply networks. It applies to pipes and fittings, as manufactured, as well as to the installed lining system. It is applicable to polyethylene (PE) pipes for both independent and interactive pressure pipe liners as well as associated fittings and joints for the construction of the lining system. It is applicable to PE pipes, fittings and assemblies intended to be used at an operating temperature of 20 °C as the reference temperature. NOTE For other operating temperatures, guidance is given in ISO 4437-5:2014.

Petroleum and natural gas industries - General requirements for offshore structures (ISO/DIS 19900:2018)
This document specifies general principles for the design and assessment of offshore structures subjected to known or foreseeable types of hazards and actions. These general principles are applicable worldwide to all types of offshore structures, including fixed structures as well as floating structures, and to all types of materials used including steel, concrete and aluminium. This document specifies principles that are applicable to design and assessment for all phases of the life of the structure, including: — the successive stages in the construction of the structure (i.e. fabrication, transportation, and installation); — its service in-place, including use and modifications during its planned life and any extension of its life; — its decommissioning. This document contains provisions for new build structures. Most of the provisions also apply to assessment of existing structures, wherever feasible, which is also described in this document.

Plastics piping systems for renovation of underground gas supply networks - Part 2: Lining with continuous pipes (ISO/DIS 11299-2:2018)
This document, read in conjunction with Part 1, specifies requirements and test methods for pipes and fittings which are part of plastics piping systems installed as continuous pipes in the renovation of underground gas supply networks. It is applicable to polyethylene (PE) pipes of three different types: PE solid wall single layered pipes (nominal outside diameter, dn), including any identification stripes; PE pipes with co-extruded layers on either or both the outside and inside of the pipe (total outside diameter, dn), as specified in Annex A, where all layers have the same MRS rating; PE coated pipes (outside diameter, dn) having a peelable, contiguous, thermoplastics additional layer on the outside of the pipe (“coated pipe”), see Annex A. In addition it covers: jointing of pipe lengths by means of butt fusion; fabricated and injection-moulded fittings made of PE;

Petroleum and natural gas industries - Cements and materials for well cementing - Part 3: Testing of deepwater well cement formulations (ISO/DIS 10426-3:2018)
This part of ISO 10426 provides procedures for testing well cements and cement blends for use in the petroleum and natural gas industries in a deepwater environment, or areas with a low seafloor temperature, or areas where low well temperatures exist. This document is a supplement to API RP 10B-3, 2nd edition (2016), the requirements of which are applicable with the additions and exclusions specified in this document. This document does not address the mitigation of shallow water flow in deepwater wells. This is addressed in API RP 65.
