Asbestos, a fibrous mineral raw material, displays a number of useful characteristics – including resistance to heat and flames, good insulation properties, high surface energy, high tensile strength, etc. Due to its fibrous nature, asbestos proved easy to process, making it the material of choice for a wide range of civil engineering products (e.g. fibre cement panels, PVC flooring, light-weight panels, industrial screed, wall coatings, plaster, etc.).

 

What we examine/ asbestos analysis

We examine material specimens and samples, dust samples and air samples for asbestos and/or man-made mineral fibres. All examination methods have been accredited by Deutsche Akkreditierungsstelle (DAkkS), Germany’s National Accreditation Body.

Material specimens and samples (building materials, technical products, raw materials) examined for asbestos to VDI Guideline 3866, Sheet 5, as well as for man-made mineral fibres, including testing for evidence of WHO respirable fibres.

Indoor air samples examined for asbestos and/or man-made mineral fibres to VDI Guidelines 3492 (status quo, control and clearance measurements) and 3861, Sheet 2 (equipment exhaust measurements) BGI/GUV-I 505-46 (workplace exposure measurements) as well as to the pertinent international standard, ISO 14966.

Dust samples/ dust particles on adhesive tape examined for asbestos and/or man-made mineral fibres (including evidence of WHO respirable fibres).

Quantification of asbestos content as per BIA method 7487 in building materials and asphalts, optionally conducted to the specifications of TRGS 517.

Determination of the carcinogenicity index for exposure to man-made mineral fibres as per BIA method 7488.

Further applications of scanning electron microscopy (SEM) analysis

In addition to examining for asbestos and/or man-made mineral fibres, scanning electron microscopy – in conjunction with energy-dispersive X-ray micro-analysis – provides a wide range of additional applications, such as:

High-resolution surface imaging (e.g. metals, glass, corrosion structures, ruptures, plastics).

Chemical identification of impurities (e.g. inclusions in glass, blooming of ceramic products and building materials, corrosions layers, faults in electronic circuits, etc.).

Chemical identification of very small sample quantities (deposits in production areas, on worktops, etc.).

Elementverteilungsabbildungen (z.B. Untersuchungen von Schweißnähten, Lötstellen, Metallen und Legierungen etc.)
