This document describes the objectives and functional requirements for the control and mitigation of fires and explosions on offshore installations used for the development of hydrocarbon resources.
This document is applicable to the following:
— fixed offshore structures;
— floating systems for production, storage, and offloading.
Mobile offshore units as defined in this document and subsea installations are excluded, although many of the principles contained in this document can be used as guidance.
This document is based on an approach where the selection of control and mitigation measures for fires and explosions primarily caused from loss of containment is determined by an evaluation of hazards on the offshore installation. The methodologies employed in this assessment and the resultant recommendations will differ depending on the complexity of the production process and facilities, type of facility (i.e. open or enclosed), manning levels, and environmental conditions associated with the
area of operation.
NOTE Statutory requirements, rules, and regulations can, in addition, be applicable for the individual offshore installation concerned.

This document gives a method for determining the resistance to cracking of steel pipes in sour service.
This test method employs a full-scale test specimen consisting of a short length of pipe (a ‘full ring’), sealed at each end to contain the sour test environment within. The test method applies to any pipe; seamless, longitudinally welded (with or without filler), helical welded, and to girth welds between pipes.
NOTE 1 The specimen is usually a pipe but can also consist of flange neck or section of a bend, or other tubular component or a combination of the above.
NOTE 2 This test method can also be used for corrosion resistant alloys (CRAs).
The method utilizes ovalization by mechanical loading to produce a circumferential stress, equal to the target hoop stress, at two diametrically opposite locations on the inside surface of the test specimen.
The test specimen is then subjected to single sided exposure to the sour test environment
NOTE 3 The test also allows measurement of hydrogen permeation rates.
WARNING — The use of this document can involve hazardous materials, operations and equipment. It does not purport to address all of the safety or environmental problems associated with its use. Attention is drawn to local and national regulations regarding use of hazardous materials, in particular for hydrogen sulfide.

This document specifies a micro gas chromatography method for the on-line or offline determination of the content of five terpenes in biomethane, namely:
— alpha-pinene
— beta-pinene
— para-cymene
— limonene
— 3-carene.
The method is specifically developed for these five compounds. Information about the compounds is given in Annex A.
The method is applicable to the determination of individual amount fractions of the five terpenes from 1 μmol/mol up to and including 10 μmol/mol. With minor modifications it can also be used for terpene amount fractions above 10 μmol/mol.

This document specifies a test method using the high-frequency reciprocating rig (HFRR), using a digital camera, for assessing the lubricating property of petroleum-based middle distillate fuels, paraffinic diesel fuels, and biodiesel blends, with and without lubricity enhancing additives, with HFRR wear scar diameters (WSDs) of 350 μm to 700 μm.
This test method applies to fuels used in diesel engines.
NOTE It is not known if this test method will predict the performance of all additive/fuel combinations.

This part of ISO 17827 specifies a method for the determination of the size distribution of particulate biofuels by the horizontally oscillating screen method. It applies to particulate uncompressed fuels with a nominal top size of 3,15 mm and above, e.g. wood chips, hog fuel, olive stones, etc. The method is intended to characterize material up to a particle size class of P63. For larger P-classes and PL-classes, the characterization is mainly done by hand sorting.

This part of ISO 17827 specifies a method for the determination of the size distribution of particulate biofuels by the vibrating screen method. The method described is meant for particulate biofuels only, namely, materials that either have been reduced in size, such as most wood fuels, or are physically in a particulate form. This part of ISO 17827 applies to particulate uncompressed fuels with a nominal top size of 3,15 mm and below (e.g. sawdust).

This document specifies a method for the determination of the content of undissolved substances, referred to as total contamination, in middle distillates, in diesel fuels containing up to 30 % (V/V) fatty acid methyl esters (FAME). The working range is from 12 mg/kg to 26 mg/kg and it was established in an interlaboratory study by applying EN ISO 4259-1 [1].
This document in general applies to products having a kinematic viscosity not exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, e.g. diesel fuel as specified in EN 590 [2].
This test method may be used for diesel fuels containing more than 30 % (V/V) FAME and for petroleum products having a kinematic viscosity exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, however in such cases the precision of the test method has not been defined.
NOTE For the purposes of this document, the term “% (V/V)” is used to represent the volume fraction, φ, of a material.
WARNING — Use of this test method may involve hazardous materials, operations and equipment. This method does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this method to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
