This document specifies basic methods for speech recognition tests for audiological applications.
NOTE Examples of speech materials are given in Annex A.
In order to ensure minimum requirements of precision and comparability between different test procedures including speech recognition tests in different languages, this document specifies requirements for the composition, validation and evaluation of speech test materials, and the realization of speech recognition tests. This document does not specify the contents of the speech material because of the variety of languages.
Furthermore, this document also specifies the determination of reference values and requirements for the realization and manner of presentation. In addition, there are features of speech tests described which are important to be specified, but which are not understood as a requirement.
This document specifies procedures and requirements for speech audiometry with the recorded test material being presented by an audiometer through a transducer, e.g. an earphone, bone vibrator, or loudspeaker arrangement for sound field audiometry. Methods for using noise either for masking the non-test ear or as a competing sound are described.
Some test subjects, for example children, can require modified test procedures not specified in this document.
Specialized tests, such as those used for evaluating directional hearing and dichotic hearing, are outside the scope of this document.

This document 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).
WARNING - 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.
IMPORTANT - 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.
NOTE 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 samples from spilled oil with those 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 can still help to constrain the possible source(s) of the spilled oil.
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 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 weathering-resistant diagnostic ratios, can have applicability in spills involving this kind of 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 [37]. Still the method can be used to analyse the type of product involved.
This method is not directly intended for identifying oil spills in matrixes like groundwater, vegetation, wildlife/tissues, soils, or sediments, and although its application in these matrices is not precluded, it requires caution. The reason for caution is that the extractable compounds in these matrices may alter and/or contribute additional compounds compared to the source sample, which if left unrecognised, can lead to “false non-matches”. It is therefore advisable to analyse background sample(s) from seemingly uncontaminated matrix. Including these “non-oil” matrices in this oil spill identification method can require additional sample preparation (e.g. clean-up) in the laboratory prior to analysis and consideration of the extent to which the matrix can affect the correlation achieved. Evaluating the possible effects in these matrices is beyond the scope of this document. Whether the method can be used for this kind of matrices may depend on the oil concentration compared to the “matrix concentration” of the samples. In matrices containing relatively high concentration of oil, a positive match can still be concluded. In matrices containing relatively low concentration of spilled oil, a false non-match or an inconclusive match could be achieved due to matrix effects.

This document provides guidance for designers of BWMS using electrolytic methods to document the risk assessment and risk reduction process over the lifecycle of the equipment, and to support its approval for use on ships by Administrations and classification societies. Specifically, this document provides basic terminology, principles, and a methodology to identify and subsequently minimize the risk of hazards in the design of BWMS using electrolytic methods. It specifies the procedures for risk assessment and risk reduction following the guidance of ISO 12100. Risks considered include: human health and safety; marine environment related to conditions on board; ship installation, operation, maintenance, and structural integrity.
This document does not address the methodology for the risk assessment of corrosion effects, toxicity and ecotoxicity of active substances, relevant chemicals, and/or other chemicals generated or used by BWMS using electrolytic methods, which is evaluated by the IMO GESAMP-Ballast Water Working Group as prescribed in the document IMO, Methodology for the Evaluation of Ballast Water Management Systems using Active Substances.
This document does not address risks associated with the end of life disposition of the BWMS.

This document specifies a method for the determination of ammonium nitrogen (NH4-N) in drinking water, groundwater, surface water, wastewater, bathing water and mineral water using the small-scale sealed tube method. The result can be expressed as NH4 or NH3 or NH3 or NH3-N.
This method is applicable to (NH4-N) concentration ranges from 0,01 mg/l to 1 800 mg/l of NH4-N. The measuring ranges of concentration can vary depending on the type of small-scale sealed tube method of different manufacturers. Concentrations even slightly higher than the upper limit indicated in the manufacturers manual relating to the small-scale sealed tube method used, cannot be reported as accurate results. Appropriate preliminary dilution of the sample shall be performed or a small-scale sealed-tube method with a different application measuring range shall be used.
All manufacturers' methods are based on the Berthelot reaction and its modifications to develop indophenol blue colour. Reagents mixtures could differ slightly based on manufacturers small-scale sealed tube method. This method is applicable to direct determination of samples by using small-scale sealed tubes for the determination of drinking water, groundwater, surface water, wastewater and on preserved samples. The method is applicable after separation of suspended materials by filtration.
