ISO/IEC 17025:2017 specifies the general requirements for the competence, impartiality and consistent operation of laboratories.
ISO/IEC 17025:2017 is applicable to all organizations performing laboratory activities, regardless of the number of personnel.
Laboratory customers, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others use ISO/IEC 17025:2017 in confirming or recognizing the competence of laboratories.

This document specifies a system for fuel quality monitoring of petrol and diesel (FQMS).

This European Standard specifies a procedure for drawing, from fuel dispensers, samples of unleaded petrol and diesel fuel to be used for the assessment of automotive fuel quality in accordance with EN 14274. This European Standard does not cover the sampling of Liquefied Petroleum Gas (LPG).
WARNING: The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ISO/IEC 17020:2012 specifies requirements for the competence of bodies performing inspection and for the impartiality and consistency of their inspection activities.
It applies to inspection bodies of type A, B or C, as defined in ISO/IEC 17020:2012, and it applies to any stage of inspection.

ISO 14596:2007 specifies a method for the determination of the sulfur content of liquid petroleum products, additives for petroleum products, and semi-solid and solid petroleum products that are either liquefied by moderate heating or soluble in organic solvents of negligible or accurately known sulfur content. The method is applicable to products or additives having sulfur contents in the range 0,001 % (m/m) to 2,50 % (m/m); higher contents can be determined by appropriate dilution. Other elements do not interfere at concentrations anticipated in the materials subject to this analysis.

ISO 8754:2003 specifies a method for the determination of the sulfur content of petroleum products, such as naphthas, unleaded motor gasolines, middle distillates, residual fuel oils, base lubricating oils and components. The method is applicable to products having sulfur contents in the range 0,03 % (by mass) to 5,00 % (by mass).

ISO 3170:2004 specifies the manual methods to be used for obtaining samples of liquid or semi-liquid hydrocarbons, tank residues and deposits from fixed tanks, railcars, road vehicles, ships and barges, drums and cans, or from liquids being pumped in pipelines.
ISO 3170:2004 applies to the sampling of petroleum products, crude oils and intermediate products, which are stored in tanks at or near atmospheric pressure, or transferred by pipelines, and are handled as liquids at temperatures from near ambient up to 200 degrees Celsius.
The sampling procedures specified are not intended for the sampling of special petroleum products which are the subject of other International Standards, such as electrical insulating oils (IEC 60475), liquefied petroleum gases (ISO 4257), liquefied natural gases (ISO 8943) and gaseous natural gases (ISO 10715).

ISO 4259:2006 covers the calculation of precision estimates and their application to specifications. In particular, it contains definitions of relevant statistical terms, the procedures to be adopted in the planning of an inter-laboratory test programme to determine the precision of a test method, the method of calculating the precision from the results of such a programme, and the procedure to be followed in the interpretation of laboratory results in relation both to precision of the test methods and to the limits laid down in specifications.
The procedures in ISO 4259:2006 have been designed specifically for petroleum and petroleum-related products, which are normally homogeneous. However, the procedures described in this International Standard can also be applied to other types of homogeneous products. Careful investigations are necessary before applying ISO 4259:2006 to products for which the assumption of homogeneity can be questioned.

This European Standard specifies requirements and test methods for marketed and delivered automotive diesel fuel. It is applicable to automotive diesel fuel for use in diesel engine vehicles designed to run on automotive diesel fuel containing up to 7 %(V/V) Fatty Acid Methyl Ester.
NOTE   For the purposes of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction and the volume fraction.

This European Standard specifies requirements and test methods for marketed and delivered unleaded petrol. It is applicable to unleaded petrol for use in petrol engine vehicles designed to run on unleaded petrol.
This European Standard specifies two types of unleaded petrol: one type with a maximum oxygen content of 3,7 % (m/m) and a maximum ethanol content of 10,0 % (V/V) in Table 1, and one type intended for older vehicles that are not warranted to use unleaded petrol with a high biofuel content, with a maximum oxygen content of 2,7 % (m/m) and a maximum ethanol content of 5,0 % (V/V) in Table 2.
NOTE 1   The two types are based on European Directive requirements [3], [4].
NOTE 2   For the purposes of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction, µ, and the volume fraction, φ.

The procedure specified may be applied to products having contents in the range 1 to 1O OOO mg/kg and is particularly suitable for distillates with less than 3OO mg/kg. Test samples which are viscous, highly aromatic, or of high content may be first diluted with a sulfur-free solvent. The procedure can be used for natural and refinery gases, also for substances supplied to the burner in the liquid state and for the determination of volatile sulfur in substances supplied to the burner in the gaseous state after vaporisation from the liquid phase. It is not suitable for heavy-duty engine oils.
