This document specifies the derivation of biological equivalence (BEQ) concentrations for results of in vitro bioassays which are based on measuring effects on a biological process such as enzyme induction or cellular growth. The concept described here can be used for any biological assay after the proof of its applicability.
To derive BEQ concentrations, the effect on a biological process caused by a sample – i.e. the activity of the sample – is expressed in terms of a concentration of a reference compound which results in an equivalent effect on the process. The term "sample" used in this document addresses environmental samples as well as defined mixtures and pure compounds used as test item in a bioassay. BEQ concentrations can be derived for environmental water samples, extracts of environmental water samples including tap water or solutions of pure chemicals or mixtures of chemicals.

This European Standard specifies general requirements and performance test procedures for portable and fixed position measuring devices (MDs) that are used in an in-line or online operating position to measure physical and chemical determinands in water. It excludes at-line devices, such as chemical test kits, and off-line devices, such as laboratory analysers.
The general requirements include functional facilities that MDs need to meet users’ applications and information that need to be included in associated documents.
The test procedures specify uniform methods to be used when determining key performance characteristics of MDs. The performance tests comprise testing carried out under laboratory and field conditions.
Statistical procedures are defined for evaluation of the test data. It is recognized that for some devices certain test procedures are not applicable.
Example values for performance characteristics for a selection of MDs for monitoring waste water effluents and receiving waters are detailed in Annex A for guidance.
This European Standard requires the manufacturer of a MD to provide more technical data for verification than does EN ISO 15839:2006 [5]. Consequently, EN ISO 15839 will be of greater assistance to manufacturers wishing to characterize a new device whereas this European Standard is more focussed on user requirements for the verification of manufacturer’s claims.

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 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 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
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.

— sample water and waste water from non-pressurized (i.e. open to atmosphere) channels or vessels;
— sample over extended periods to collect discrete or composite samples based on time, event or flow proportional sampling.
It does not include sampling systems built into online and in-line analysers.
The general requirements include functional facilities that samplers need to meet users’ applications and information that needs to be included in associated documents.
The test procedures specify uniform methods to be used when determining key performance characteristics of samplers at one or more set sample volume. It is for the sampler manufacturer and/or user to decide on the required set sample volume(s). All of the test procedures are to be carried out under laboratory conditions. It is recognized that for some samplers, certain test procedures are not applicable.
Statistical procedures are specified for evaluation of the test data. Some example calculations are provided.
Specific sample integrity requirements are specified for samplers to be used for the collection of samples of final effluent or influent for the purpose of monitoring the performance of urban waste water treatment works. Samplers to be used for other industrial applications do not need to be assessed against these specific sample integrity requirements.
This document does not cover the installation and on-going use of samplers.

This European Standard specifies general requirements and performance test procedures for portable and fixed position measuring devices (MDs) that are used in an in-line or online operating position to measure physical and chemical determinands in water. It excludes at-line devices, such as chemical test kits, and off-line devices, such as laboratory analysers.
The general requirements include functional facilities that MDs need to meet users’ applications and information that need to be included in associated documents.
The test procedures specify uniform methods to be used when determining key performance characteristics of MDs. The performance tests comprise testing carried out under laboratory and field conditions.
Statistical procedures are defined for evaluation of the test data. It is recognized that for some devices certain test procedures are not applicable.
Example values for performance characteristics for a selection of MDs for monitoring waste water effluents and receiving waters are detailed in Annex A for guidance.
This European Standard requires the manufacturer of a MD to provide more technical data for verification than does EN ISO 15839:2006 [5]. Consequently, EN ISO 15839 will be of greater assistance to manufacturers wishing to characterize a new device whereas this European Standard is more focussed on user requirements for the verification of manufacturer’s claims.

This document specifies a method for the determination of certain cyclic volatile methylsiloxanes (cVMS) in environmental water samples with low density polyethylene (LDPE) as a preservative and subsequent liquid-liquid extraction with hexane containing 13C-labeled cVMS as internal standards. The extract is then analysed by gas chromatography-mass spectrometry (GC-MS).
NOTE Using the 13C-labeled, chemically identical substances as internal standards with the same properties as the corresponding analytes, minimizes possible substance-specific discrimination in calibrations. Since these substances are least soluble in water, they are introduced via the extraction solvent hexane into the system.

The purpose of this document is to describe test plans and different operating methodologies of these test plans to define and verify the acceptable length of stability of a substance in a sample under specified conditions of preservation (temperature, matrix, light, addition of a stabilizer, where appropriate, type of preservation etc.) before starting analytical protocols (chemicals and physico-chemicals analysis). Biological and microbiological methods are excluded.
It is necessary to have an analytical method with performances that have already been characterized (repeatability, intermediate precision, trueness, accuracy and uncertainty) in order to perform the stability study and implement its test plans.
