This document describes the characteristics of working suspensions of nano-objects to be considered when conducting in vitro assays to evaluate inherent nano-object toxicity. In addition, the document identifies applicable measurement methods for these characteristics. This document is applicable to nano-objects, and their aggregates and agglomerates greater than 100 nm. This document intends to help clarify whether observed toxic effects come from tested nano-objects themselves or from uncontrolled sources.

This document specifies requirements and provides recommendations for the interpretation of observations in order to reach opinions that answer questions that are relevant for decision making in investigations or legal proceedings. This document states requirements that are applicable to all forensic disciplines. This document states requirements that apply when the opinion is based directly on human judgment and when the opinion is based on interpretation through a statistical model. This document is applicable to interpretation that occurs at a scene, within a forensic facility or within a judicial setting. Interpretation is not necessary, and the requirements of this standard do not apply, if the observations resulting from the analysis directly answer the relevant question.

This document specifies requirements and provides recommendations for reporting of forensic work. It is applicable to the reporting of forensic work performed at a scene and within a forensic facility. The requirements facilitate the preparation and issuing of reports that are accurate, clear, transparent, complete, unambiguous, impartial and suitable for their intended use. This document also includes requirements relating to the review of case records and reports, the issuance and control of reports, and requirements related to testimony.

This document specifies a method for the enumeration of intestinal enterococci in water. The method is based on the growth of target organisms in a liquid medium and calculation of the “Most Probable Number” (MPN) of microorganisms by reference to MPN tables or using informatic programs. The test described in this document relies upon the detection of intestinal enterococci based upon expression of the enzyme ß-D-glucosidase. This method provides a confirmed result in 24 h with no requirement for confirmation of positive wells. This method can be applied to a range of types of water (for example, drinking water, bathing water, groundwater, surface water and wastewater), including those containing an appreciable amount of suspended matter and high background counts of heterotrophic bacteria. For marine waters, enterococci are best enumerated using diluted samples.

This document considers atmospheric precipitation and defines the procedures and equipment to perform laboratory and field tests, in steady-state conditions, for the calibration, check and metrological confirmation of non-catching precipitation measurement instruments. It provides a classification of non-catching measurement instruments based on their laboratory performance. The classification does not relate to the physical principle used for the measurement, nor does it refer to the technical characteristics of the instrument assembly but is solely based on the instrument calibration. Attribution of a given class to an instrument is not intended as a high/low ranking of its quality but rather as a quantitative standardized method to declare the achievable measurement accuracy to provide guidance on the suitability for a particular purpose, while meeting the user’s requirements.
