Construction products: Assessment of release of dangerous substances - Sampling and quantitative determination of asbestos in construction products
This document summarizes methods for sampling, sample preparation and identification of asbestos in construction products. This document specifies appropriate sample preparation procedures for the quantitative analysis of the asbestos mass fraction in natural, manufactured or recycled large mineral aggregates and construction products of fine mineral particle size materials. This document describes the identification of asbestos by polarized light microscopy (PLM) and dispersion staining, scanning electron microscopy (SEM) with energy dispersive X-ray analysis or transmission electron microscopy (TEM) with energy dispersive X-ray and electron diffraction analysis.
NOTE This document is intended for microscopists familiar with polarized light, transmission electron- and scanning electron microscopy methods and the other analytical techniques specified (see ISO 10312, ISO 13794, ISO 14966, [McCrone et al., 1984], [Su et al., 1995]). It is not the intention of this document to provide instructions on basic analytical techniques.
Bauprodukte: Bewertung der Freisetzung von gefährlichen Stoffen - Probenahme und quantitative Bestimmung von Asbest in Bauprodukten
Dieses Dokument fasst die Probenahmeverfahren, die Probenvorbereitung und die Identifizierung von Asbest in Bauprodukten zusammen. Dieses Dokument legt geeignete Verfahren zur Probenvorbereitung für die quantitative Analyse des Massenanteils von Asbest in natürlichen, hergestellten oder rezyklierten großen mineralischen Gesteinskörnungen und Bauprodukten aus mineralischen Feinkornmaterialien fest. Dieses Dokument beschreibt die Identifizierung von Asbest durch Polarisationsmikroskopie (PLM) und Dispersionsfärbung, Rasterelektronenmikroskopie (REM) mit energiedispersiver Röntgenanalyse oder Transmissionselektronenmikroskopie (TEM) mit energiedispersiver Röntgen- und Elektronenbeugungsanalyse.
ANMERKUNG Dieses Dokument richtet sich an Mikroskopiker, die mit den Verfahren der Polarisations-, Transmissions- und Rasterelektronenmikroskopie und den anderen festgelegten Analyseverfahren vertraut sind (siehe ISO 10312, ISO 13794, ISO 14966, [McCrone et al., 1984], [Su et al., 1995]). Es ist nicht Zweck dieses Dokuments, Anleitungen zu grundlegenden Analyseverfahren zu geben.

Gradbeni proizvodi - Ocenjevanje sproščanja nevarnih snovi - Vzorčenje in kvantitativno določanje azbesta v gradbenih proizvodih
V tem dokumentu so povzete metode za vzorčenje, pripravo vzorcev in določevanje azbesta v gradbenih proizvodih. Ta dokument določa ustrezne postopke priprave vzorcev za kvantitativno analizo masnega deleža azbesta v naravnih, umetnih ali recikliranih velikih mineralnih agregatih in gradbenih proizvodih iz mineralnih materialov z zelo majhno velikostjo delcev. Opisuje določevanje azbesta s polarizirano svetlobno mikroskopijo (PLM) in disperzijskim obarvanjem, vrstično elektronsko mikroskopijo (SEM) z energijsko-disperzivno rentgensko analizo oziroma presevno elektronsko mikroskopijo (TEM) z energijsko-disperzivno rentgensko analizo in elektronsko difrakcijsko analizo.
OPOMBA: Ta dokument je namenjen mikroskopistom, ki poznajo metode polarizirane svetlobne mikroskopije, presevne elektronske mikroskopije in vrstične elektronske mikroskopije ter druge navedene analitske tehnike (glej standarde ISO 10312, ISO 13794, ISO 14966, [McCrone et al., 1984], [Su et al., 1995]). Namen tega dokumenta ni zagotavljanje navodil za osnovne analitske tehnike.
