1.1 This guide outlines procedures for the petrographic examination of samples representative of materials proposed for use as aggregates in cementitious mixtures or as raw materials for use in production of such aggregates. This guide is based on Ref (1).1.2 This guide outlines the extent to which petrographic techniques should be used, the selection of properties that should be looked for, and the manner in which such techniques may be employed in the examination of samples of aggregates for concrete.1.3 The rock and mineral names given in Descriptive Nomenclature C 294 should be used, insofar as they are appropriate, in reports prepared in accordance with this guide.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This document gives examples of digestion methods referred to groups of materials for the X-rays fluorescence method of oxidic raw and basic materials.
This part of ISO 16000 specifies procedures to be used in planning of air measurements to determine theconcentrations of asbestos in indoor atmospheres. Careful planning of the measurement strategy is important,because the results can become the basis of recommendations for major building renovations, or for thereturn of a building to normal occupancy status after removal of asbestos-containing materials.This part of ISO 16000 uses the following definition for indoor environments as specified in ISO 16000-1:-- dwellings having living rooms, bedrooms, do-it-yourself (DIY) rooms, recreation rooms, cellars, kitchens and bathrooms;-- workrooms or workplaces in buildings which are not subject to health and safety inspections in regard to air pollutants (for example, offices and sales premises);-- public and commercial buildings (for example, hospitals, schools, kindergartens, sports halls, libraries, restaurants and bars, theatres and other function rooms);-- cabins of vehicles and public transport.
The international standard ISO 16000-27 specifies a method giving an index for the numerical concentration of fibrous structures with fibres equal or greater than 0,2 µm in diameter in settled dust on surfaces and their classification into specific substance groups (e. g. chrysotile, amphibole asbestos, other inorganic fibres). It is primarily applicable to indoor areas, but it is also suitable for certain outdoor situations. A sampling technique for collection of settled dust using adhesive tape is described. The method incorporates an analytical method for evaluation of the collected samples by scanning electron microscopy. The result can be specified in asbestos structures per unit area and/or classified into four different loading classes. The analytical sensitivity depends on the area examined and can be as low as 10 structures per cm2.
