These international guidelines are based on the assumption that monitoring of environmental components (atmosphere, water, soil and biota) as well as food quality is performed to ensure the protection of human health[5][7][8][9][10][11][12]. The guidelines constitute a basis for the setting of national regulations, standards, and inter alia, for monitoring air, water and food in support of public…

This document provides a)    a discussion of alternative experimental designs for the determination of trueness and precision measures including reproducibility, repeatability and selected measures of intermediate precision of a standard measurement method, including a review of the circumstances in which their use is necessary or beneficial, and guidance as to the interpretation and application…

This document specifies the common conventions required for the interchange of specific patient data (demographic, recording conditions ...), ECG signal data and metadata, ECG measurements and ECG annotations, and ECG interpretation results. This document specifies the content and structure of the information which may be interchanged between digital ECG electrocardiographs/devices and computer…

This document provides information and general guidance about the methods for measuring the indoor light stability of reflection prints, both colour and monochrome, transparent or translucent films, and photographic prints for backlit displays. This document is relevant to the selection and operation of the methods of exposure to radiation and environmental stress factors described in detail in…

Scope 1.1 General 1.1.1 This Standard covers solid waste containment interceptors intended for commercial and residential applications and specifies requirements for materials, physical characteristics, performance testing, and markings. 1.1.2 Solid waste containment interceptors covered by this standard include trap interceptors and non-trap interceptors of various configurations (see…

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…

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…

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…

This document specifies a laboratory test method for indirectly measuring the adhesion performance of repair material to wet concrete crack surfaces by qualitatively, as a pass/fail at predetermined time, against predetermined amount of weight exerted on the repair material adhesion. NOTE            This document classifies and categorizes materials that are tested into families of similar…
