Asbestos test: We examine these materials for asbestos and this is how you commission an analysis

 

In our descriptive video, we explain step by step how you can order an asbestos analysis from us. Find out which materials we test for asbestos and how the process works.

 

 

What is asbestos?

 

Asbestos is a collective name for a group of natural, fibrous silicate minerals. These fibers are characterized by their exceptional tensile strength, heat resistance and resistance to chemical influences. Due to these excellent properties, asbestos was used in numerous products and materials, especially in construction, until the 1990s.

 

Why is asbestos so dangerous?

 

Asbestos is dangerous due to its fibrous structure and the associated health risks. The individual asbestos fibres are virtually invisible to the naked eye.

 

If asbestos fibres are released – for example through damage, ageing or improper handling of materials containing asbestos – they can be inhaled and lead to serious diseases in the lungs, which are often not detected until years or decades later.

 

A common consequence is asbestosis, a hardening and scarring of the lung tissue that restricts respiratory function. Asbestos is also carcinogenic and can cause lung cancer and mesothelioma (tumors of the chest or peritoneum).

 

Artificial mineral fibres (AMF), which have been used as substitutes for asbestos, are also not harmless. Studies show that they can also pose similar health risks.

 

When was asbestos used?

 

Asbestos has been used extensively in Germany since the 1930s. Especially in the 1950s to 1980s, the use of asbestos experienced a peak. During this time, it has been used in numerous construction products, including roof and façade panels, piping, flooring such as "floor flex panels" or "cushion vinyl", plasters, fillers and tile adhesives.

 

It was not until the 1970s that the health risks of asbestos were increasingly recognised. In Germany, a comprehensive ban on the manufacture, placing on the market and use of asbestos and products containing asbestos came into force on 31 October 1993.

Procedure for detecting asbestos

As an experienced materials analysis laboratory, CRB uses reliable and precise techniques such as scanning electron microscopy (SEM) and X-ray microanalysis (EDX) to determine asbestos for a wide variety of samples.

Scanning Electron Microscopy (SEM)

With scanning electron microscopy (SEM), we can visualize the microscopic fibers of asbestos in your sample. This method allows a detailed view of the fibers, including their length, thickness, and structural features.

The SEM method uses a focused electron beam that scans over the sample. This generates high-resolution images that make it possible to reliably identify asbestos even in very fine particles or highly fragmented samples.

X-ray microanalysis, energy-dispersive X-ray spectroscopy (EDX)

X-ray microanalysis (EDX) is often used in combination with SEM. Here, characteristic X-rays are emitted by the interaction of the electron beam with the sample. The analysis of these X-rays makes it possible to determine the chemical composition of the sample, as each element has a unique X-ray spectrum.

Depending on the type of material in your sample and the expected asbestos concentration, we carry out different preparation and analysis methods. As a private customer, you do not have to worry about choosing the appropriate method when ordering an asbestos test. We take care of that for you.

Asbestos analysis procedure: How to order an asbestos test

Commissioning an asbestos analysis from CRB is simple: you first select the material online and give your sample a unique designation. You then take a sample of the suspect material, pack it airtight, label the sample with the same sample designation and send the sample to our laboratory. Padded envelopes are particularly suitable for the safe shipment of the sample (further information on safe sampling and sample dispatch). Depending on the postal delivery time, your shipment will reach us the next day.

As soon as we have received the sample, we will analyze it and within 3 to 4 working days after receipt of the sample, you will receive a court-proof test report by e-mail.

Please note that CRB does not evaluate the results of the assay or make any evaluation recommendations. If you have any questions about the results, please feel free to contact us. If you would like a professional assessment, you are also welcome to contact us: We will then put you in touch with a competent contact person in your area who can advise you further.

Result of the asbestos analysis: What information does the test report provide?

There are two possible results in an asbestos analysis:

(a) 'containing asbestos: yes' with a classification into quantity classes, or

b) "Asbestos not proven".

In the event of a negative result ("asbestos not proven"), the detection limits specified in the test report are also relevant. Depending on the type of material, the homogeneity and the expected asbestos concentration, different preparation techniques and types of examination are used for the examination of the material samples. You can read more information about the resulting different detection limits here.

SBH-method

 

The SBH-method is a procedure developed by the Schulbau Hamburg specified procedure that was and is used for the analysis of paint residues, plasters and fillers that may contain asbestos.

 

In this process, individual or mixed samples are incinerated at 450 °C and acid-treated to accumulate asbestos in the sample.

 

Preparation methods of the 'SBH method' are taken up and described in June 2017 in the guideline VDI 3866, sheet 5 and in the short report Asbestos in plasters, fillers and tile adhesives – Refurbishment of Material samples engrossed.

 

CRB conducts tests of plasters, fillers and tile adhesives in accordance with Annex B of the VDI 3866 guideline, sheet 5:2017-06.

Concealed products such as fillers, tile adhesives and plasters

Recently, concealed products such as fillers, tile adhesives and plasters have increasingly become the focus of attention. Asbestos was often added to these in very small quantities to improve the processing properties of the product. Today, therefore, the asbestos-containing areas are often found under wallpaper or, as in the case of fillered cable slots, they are only present very selectively. These concealed products pose a significant danger to anyone who accidentally and/or improperly handles them. This can lead to significant fiber releases. In particular, buildings that were built or modernized/renovated after the absolute ban on asbestos in 1993, but at least until 1995, are suspected.


Special requirements for laboratory analysis

Since the plasters, fillers and tile adhesives to be examined sometimes have asbestos contents of < 1%, the asbestos in the sample material may be present in a polymer matrix or the asbestos is covered by other polymer aggregates, the sample material must be prepared for laboratory analysis by homogenisation, ashing and acid treatment. Since the preparation of composite samples (see also 'SBH method', an analytical regulation introduced in the Hanseatic City of Hamburg for the examination of school buildings) makes sense in order to reduce the costs of analysis, but the formation of composite samples may lead to a further dilution of the asbestos contents in the laboratory sample, an analytical method with a detection limit of less than 0.01% by weight must be used.


Analytical options for the analysis for asbestos in plasters, fillers and tile adhesives

There are 2 types of investigations based on VDI 3866, sheet 5:2017-06. VDI 3866 takes into account the requirements of the IFA / BIA procedure 7487:1997-04 and ISO 22262-2:2014-09.

Preparation: ashing, acid treatment, filtration from a suspension onto a nuclear pore filter.

Qualitative result with a mass estimate of the quantity proportion of asbestos according to the mass content classes of VDI 3866, sheet 5, detection limit of the method 0.001 percent by weight.


2. Quantitative study according to VDI 3866, sheet 5:2017-06 based on IFA/BIA procedure 7487

Preparation: ashing, acid treatment, filtration from a suspension onto a nuclear pore filter.

Result quantitatively with an indication of the asbestos concentration in percent by mass. Detection limit of the method 0.001 percent by mass.
