This part of ISO 20088 describes a method for determining the resistance of a Cryogenic Spill Protection (CSP) systems to a cryogenic jet as a result of a pressurised release which does not result in immersion conditions. It is applicable where CSP systems are installed on carbon steel and will be in contact with cryogenic fluids.

A cryogenic jet may be formed upon release from process equipment operating at pressure (e.g., some liquefaction processes utilise 40 - 60 bar operating pressure). Due to high pressure discharge, the cryogenic spillage protection may be compromised by the large momentum combined with extreme cryogenic temperature.

Although the test uses liquid nitrogen (LIN) as the cryogenic liquid, the test described in this standard is representative of a release of LNG, through a 20mm orifice or less, at a release pressure of 6 barg or less, based upon simulated parameters 1 m from the release point. Confidence in this test being representative is based upon a comparison of the expected dynamic pressure of the simulated release in comparison with dynamic pressure from releases in accordance with this part of the ISO 20088 standard.

It should be recognised that it is not practical in this test to cover the whole range of cryogenic process conditions found in real plant conditions; in particular the test does not cover high pressure cryogenic jet releases that may be found in refrigeration circuits and in LNG streams immediately post-liquefaction.

LIN is used as the cryogenic medium due to the ability to handle the material at the pressures described in this part of the standard safely. The test condition is run at 8 barg pressure.

Part 1 of the standard covers cryogenic release scenarios which may lead to immersion conditions for steel work protected by cryogenic spill protection as a result of a jet release or low pressure release of LNG or LIN. Part 2 of the standard covers vapour phase exposure conditions as a result of a jet release or low pressure release of LNG or LIN.

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.

This document, read in conjunction with ISO 11299-1, 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;

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.

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.

This method, which permits to measure the quantity of oil separated from lubricating grease in the conditions of the test, is useful to predict the storage behaviour of greases on storage in pails and drums.

This method does not apply to very soft greases that, during the test, flow unchanged through the sieve.
