This document establishes a framework for the characterization of physical and chemical properties of tyre and road wear particles (TRWP) using published analytical standards. It is applicable to laboratory-generated TRWP and TRWP collected in the environment. NOTE            This framework focuses primarily on published International Standards, but also includes standards published by other…

This document specifies a method of determining, using an Alveograph, the rheological properties of different types of dough obtained from common wheat flour (Triticum aestivum L.) produced by industrial milling or laboratory milling. It describes the Alveograph test and how to use a laboratory mill to produce flour in two stages: —    stage 1: preparation of the wheat grain for milling to make…

This document specifies a method to evaluate the capability of portable household air cleaners to reduce the concentration and viability of key experimentally generated bioaerosols in a specified chamber. Indoor air free of harmful microbes is important to the health of occupants. This is particularly relevant with regard to increased time spent indoors. Air cleaners are used to reduce the…

1 Scope This document specifies procedures and test methods used to demonstrate the cleaning efficacy of washer-disinfectors (WD) and their accessories intended to be used for cleaning of reusable medical devices. NOTE 1 The requirements can be used for washer-disinfectors intended for use with other articles used in the context of medical, dental, laboratory, pharmaceutical and veterinary…

This document describes a test method to determine the activity concentration of atmospheric tritium by trapping tritium in air by bubbling through a water solution. Atmospheric tritium activity concentration levels are expressed in becquerel per cubic metre (Bq∙m-3). The formulae are given for a sampling system with four bubblers. They can also be applied to trapping systems with only one…

Scope 1.1 This standard presents methodologies for characterizing and quantifying coarse, fine, and ultrafine particles and volatile organic compound (VOC) emissions from operating three-dimensional (3D) printers under normal conditions of use in defined indoor environments including classroom, office, and residential scenarios. 1.2 This method primarily applies to the emissions of particles…

This document specifies requirements and good practice recommendations for the collection and transport of samples intended for medical laboratory examinations. This document is applicable to medical laboratories and service providers, which can be independent from the medical laboratory, involved in laboratory pre-examination processes that include the examination request, patient preparation…

This document defines terms related to cell line authentication in the field of biotechnology. It describes the general principles, detection strategies and analytical methods for cell line authentication. It specifies requirements and key considerations for method selection, quality control parameters, data analysis and reporting. This document is applicable to routine inspection of cell lines…

This document provides a method to ensure the performance of continuous monitoring TRO sensors, which can be installed in a BWMS or elsewhere in a ship, taking into consideration environmental factors associated with shipboard conditions, such as high salinity, vibration, variation in humidity and temperature, and predictable sea conditions. This document is intended for use by BWMS manufacturers…

1 Scope 1.1 Introduction This Standard describes the test procedures, test set-ups, and calculations required to determine the performance, capacities, energy consumption, and overall efficiency of gas-fired and oil-fired combined radiant space and water heating systems (combos) with hydronic heat distribution. 1.2 Type of standard This Standard establishes laboratory methods for testing and…
