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.

This document describes a method to firstly identify the specific nature of oils spilled in the environment and secondly compare the chemical composition of spilled oil or oily samples with that of suspected sources. Specifically, the document describes the detailed analytical methods and data processing specifications for identifying the specific nature of oil spills and establishing their correlation to suspected sources. 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 may still help constrain the possible source(s) of the spilled oil.

This methodology is restricted to petroleum related products containing a significant proportion of hydrocarboncomponents 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 may not be appropriate for lower boiling oils (e.g. kerosenes, jet fuels, or gasoline), the general concepts described in this methodology, i.e. statistical comparison of weatheringresistant diagnostic ratios, may have applicability in spills involving lower boiling oils.

Paraffin as petroleum product (for candles, etc.) is outside the scope of this method, because too many compounds have been removed during the production process. Still the method can be used to analyse the type of product involved.

This document specifies a method for the determination of the dissolved anions chlorate, chloride, and chlorite in water with low contamination (e.g. drinking water, raw water or swimming pool water).

An appropriate pretreatment of the sample (e.g. dilution) and the use of a conductivity detector (CD), UV detector (UV) or amperometric detector (AD) make the working ranges given in Table 1 feasible.

Table 1 — Working ranges of the analytical method

a   The working range is restricted by the ion-exchange capacity of the columns. Dilute the sample in to the working range, if necessary.

b   The minimum working range for chlorite of 0,05 mg/l was obtained using calibration checks, but the round robin trials (Annex A, Table A.4) showed that it is difficult to obtain this with sufficient accuracy. Thus great care shall be taken when working in the lower range of this method.

This document specifies the representation of latitude and longitude and optionally height or depth compatible with previous editions of ISO 6709.

This document also supports the representations of other coordinate types and time that may be associated with those coordinates as defined through one or more coordinate reference systems (CRS).

This document describes a text string of coordinates, suitable for electronic data exchange, for one point including reference system identification to ensure that the coordinates unambiguously represent the position of that point. Files containing multiple points with a single common reference system identification are out of scope. This document also describes a simpler text string structure for coordinate representation of a point location that is more suitable for human readability.
