Oil spill identification - Petroleum and petroleum related products - Part 2: Analytical method and interpretation of results based on GC-FID and GC-low resolution-MS analyses

Oil spill identification - Petroleum and petroleum related products - Part 2: Analytical method and interpretation of results based on GC-FID and GC-low resolution-MS analyses

This document specifies a method to identify and compare the compositional characteristics of oil samples. Specifically, it describes the detailed analytical and data processing methods for identifying the characteristics of spill samples and establishing their correlation to suspected source oils. Even when samples or data from suspected sources are not available for comparison, establishing the specific nature (e.g. refined petroleum, crude oil, waste oil, etc.) of the spilled oil still helps to constrain the possible source(s).
This methodology is restricted to petroleum related products containing a significant proportion of hydrocarbon-components with a boiling point above 150 °C. Examples are: crude oils, higher boiling condensates, diesel oils, residual bunker or heavy fuel oils, lubricants, and mixtures of bilge and sludge samples, as well as distillate fuels and blends. While the specific analytical methods are perhaps not appropriate for lower boiling oils (e.g. kerosene, jet fuel, or gasoline), the general concepts described in this methodology, i.e. statistical comparison of weathering-resistant diagnostic ratios, are applicable in spills involving these kinds of oils.
Paraffin based products (e.g. waxes, etc.) are outside the scope of this method because too many compounds are removed during the production process [37]. However, the method can be used to identify the type of product involved.
Although not directly intended for identifying oil recovered from groundwater, vegetation, wildlife/tissues, soil, or sediment matrices, they are not precluded. However, caution is needed as extractable compounds can be present in these matrices that alter and/or contribute additional compounds compared to the source sample. If unrecognized, the contribution from the matrix can lead to false “non-matches”. It is therefore advisable to analyse background sample(s) of the matrix that appear unoiled.
When analysing “non-oil” matrices additional sample preparation (e.g. clean-up) is often required prior to analysis and the extent to which the matrix affects the correlation achieved is to be considered. Whether the method is applicable for a specific matrix depends upon the oil concentration compared to the “matrix concentration”. In matrices containing high concentrations of oil, a positive match can still be concluded. In matrices containing lower concentrations of oil, a false “non-match” or an “inconclusive match” can result from matrix effects. Evaluation of possible matrix effects is beyond the scope of this document.

Oil spill identification - Petroleum and petroleum related products - Part 2: Analytical method and interpretation of results based on GC-FID and GC-low resolution-MS analyses
EN 15522-2:2023

This document specifies a method to identify and compare the compositional characteristics of oil

samples or data from suspected sources are not available for comparison, establishing the specific nature
(e.g. refined petroleum, crude oil, waste oil, etc.) of the spilled oil still helps to constrain the possible
source(s).
This methodology is restricted to petroleum related products containing a significant proportion of
hydrocarbon-components with a boiling point above 150 °C. Examples are: crude oils, higher boiling
condensates, diesel oils, residual bunker or heavy fuel oils, lubricants, and mixtures of bilge and sludge
samples, as well as distillate fuels and blends. While the specific analytical methods are perhaps not
appropriate for lower boiling oils (e.g. kerosene, jet fuel, or gasoline), the general concepts described in
this methodology, i.e. statistical comparison of weathering-resistant diagnostic ratios, are applicable in
spills involving these kinds of oils.
Paraffin products (e.g. waxes, etc.) are outside the scope of this method because too many compounds
are removed during the production process [37] to correctly distinguish them from each other. However,
the method can be used to identify the type of product involved.
Although not directly intended for identifying oil recovered from groundwater, vegetation,
wildlife/tissues, soil, or sediment matrices, they are not precluded. However, caution is needed as
extractable compounds can be present in these matrices that alter and/or contribute additional
compounds compared to the source sample. If unrecognized, the contribution from the matrix can lead
to false “non-matches”. It is therefore advisable to analyse background sample(s) of the matrix that
appear unoiled.
When analysing “non-oil” matrices additional sample preparation (e.g. clean-up) is often required prior
to analysis and the extent to which the matrix affects the correlation achieved is to be considered.
Whether the method is applicable for a specific matrix depends upon the oil concentration compared to

concluded. In matrices containing lower concentrations of oil, a false “non-match” or an “inconclusive

Oil spill identification - Petroleum and petroleum related products - Part 1: Sampling
EN 15522-1:2023

EN 15522-1 provides guidance on taking and handling samples, that are collected as part of an investigation into the likely source of a crude oil or petroleum product spill into a marine or aquatic environment. Guidance is given on taking samples from both the spill and its potential source.
Mostly, oil sampling is part of legal procedures and has to be treated like any other preservation of evidence (legal sampling). If samples are to be used in connection with legal proceedings, this document should be read in conjunction with any documents issued by the regulatory authorities in the country or countries in question where the spill has occurred.
Taking samples may involve hazardous materials, operations and equipment.
This document is not intended to address all the safety and health aspects associated with the guidance given. It is the responsibility of the user to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note: Most countries have special trained teams to take samples on board of ships. As police officer or law enforcer don’t take unnecessary risks and ask assistance from such a team when available.
For the sake of clarity, the word ‘oil’ is used throughout this document. It can equally refer to crude oil, a petroleum product or mixtures of such.

Electricity metering equipment (AC) - General requirements, tests and test conditions - Part 31: Product safety requirements and tests (IEC 62052-31:2024)
EN IEC 62052-31:2024

IEC 62052-31:2024 specifies general safety requirements and associated tests, with their appropriate conditions for type testing of directly connected, transformer-operated or transducer-operated AC and DC electricity meters and load control equipment. This document applies to electricity metering equipment designed to:
• measure and control electrical energy on electrical networks (mains) with voltage up to 1 000 V AC, or 1 500 V DC;
• have all functional elements, including add-on communication modules, enclosed in, or forming a single meter case with exception of indicating displays;
• operate with integrated displays (electromechanical or static meters);
• operate with detached indicating displays, or without an indicating display (static meters only);
• wall-mounted or to be installed in specified matching sockets or racks;
• optionally, provide additional functions other than those for measurement of electrical energy.
This document also applies to transducer-operated meters or meters designed for operation with Low Power Instrument Transformers (LPIT) or sensors (as defined in the IEC 61869 series).
When equipment in scope of this document is designed to be installed in a specified matching socket, then the requirements apply to, and the tests are performed on, equipment installed in its specified matching socket. However, requirements for sockets and inserting / removing the meters from the socket are outside the scope of this document.
This document is also applicable to auxiliary input and output circuits, operation indicators, and test outputs of equipment for electrical energy measurement.
Equipment used in conjunction with equipment for electrical energy measurement and control may need to comply with additional safety requirements. See also Clause 13.
This document does not apply to:
• meters rated to operate with voltage exceeding 1 000 V AC, or 1 500 V DC;
• metering systems comprising multiple devices physically remote from one another;
• portable meters;
• meters used in rolling stock, vehicles, ships and airplanes;
• laboratory and mobile meter test equipment;
• reference standard meters;
• conventional or low power instrument transformers;
• equipment with solid-state or other non-electromechanical supply and load control switches.
The safety requirements of this document are based on the following assumptions:
• metering equipment has been installed correctly;
• metering equipment is used generally by ordinary persons, including meter readers and consumers of electrical energy. In many cases, it is installed in a way that it is freely accessible. Its terminal covers cannot be removed, and its case cannot be opened without removing seals (if present) and using a tool;
• during normal use all terminal covers, covers and barriers providing protection against accessing hazardous live parts are in place;
• for installation, configuration, maintenance and repair it may be necessary to remove terminal cover(s), (a part of) the case or barriers so that hazardous live parts may become accessible. Such activities are performed by skilled persons, who have been suitably trained to be aware of working procedures necessary to ensure safety. Therefore, safety requirements covering these conditions are out of the Scope of this document.
