Testing of hydraulic brake hose assemblies by Standard SAE J1401

Institute for testing and certification offers a new service in a field of automotivetesting of Hydraulic Brake Hose Assemblies by Standard SAE J1401. For detailed informations please contact our expert from Physical Testing Laboratory mr. Radek Matejka rmatejka@itczlin.cz.


New method for determination of organometallic complexes

Our analytical laboratory has implemented new method for determination of organometallic complexes (i.e. alkyl mercury) by cation chromatography, coupled to ICP-MS detection. This group of substances is represented for example by Trimerosal, used as fungicide or fungistatic agent. Such a substances can be limited for example in vaccines or contact lens solutions.

Determination of crack bridging properties

Laboratory of building materials has introduced new test device for test according to EN 1062-7 for “Determination of crack bridging properties”. On this device also another tests of paints, varnishes, coating materials and coating systems can be performed, list of standards is attached in this note. contact: rmikac@itczlin.cz


Food contact materials - Mineral oils MOSH and MOAH determination in packaging:

With respect to the clients requests the new method was developed in ITC laboratories - Mineral oils MOSH and MOAH determination in packaging. Aromatic mineral oils (MOAH) are considered by EFSA as potentially carcinogenic and are given high attention now. Limit values for migration were published on a national basis by German Federal Institute for Risk Assessment (BfR). For further information you can contact Laboratory of Analytical Chemistry - fpuype@itczlin.cz; analyt@itczlin.cz

Physical Testing Laboratory

Testing » Accredited Testing Laboratory No. 1004

The Physical Testing Laboratory is one of the main departments of the Accredited Testing Laboratory No. 1004. It was founded during the period of existence of the Research Institute for Rubber and Plastics and currently also the majority of testing methods are focused on problems with polymer materials. Following the development of the automotive industry, hundreds of unique tests were introduced at the testing laboratory in accordance with many technical standards, which, in connection with analytical laboratory services create the conditions for the provision of a wide range of professional services, utilised by clients from all over Europe.

MECHANICAL TESTS

  • Static
  • Destruction and deformation
  • Short- or long-term
  • Dynamic
  • With consecutive or alternating stress

  • Heat and thermal conductivity
  • Melting point

TESTING FLAMMABILITY AND FIREPROOF PROPERTIES

Tests are carried out mostly in special multi-purpose chambers, allowing the testing of either small or large samples. In particular the fireproof characteristics of building materials are evaluated with the use of computer technology, which helps to refine and improve the quality of professional services.

  • Flammability class of building materials
  • Ignitability of materials

  • Flash-point
  • Fire-point
  • Ease of ignition of vertically oriented samples
  • Speed of flame propagation of textiles
  • Tablet test of flooring materials
  • Hot nut test of flooring materials
  • Cigarette test of bedding and seating furniture
  • Match test of bedding and seating furniture
  • Resistance to a small amount of molten metal

EVALUATION OF OPTICAL PROPERTIES

  • Optical and electron microscopy
    • The laboratory is equipped with a scanning electron microscope with the appropriate technical equipment and with optical polarising microscopes connected to the display analyser, which allows the evaluation of the size of individual particles or the thickness of individual layers of material and the processing of data measured according to statistical parameters and histograms from microscopic images transmitted to the analyser.
  •  
  • Spectral analysis and objective measurement of chromaticity
    • measurement of the spectral dependence of the absorbance and transmittance in the UV and VIS bands of the electromagnetic spectrum; also measurement in the visible spectrum of the spectral dependence of remission.
    • determination of the efficiency of protective filters against UV radiation in the UV-A and UV-B and UV-C bands
    • measurement of shielding factors
    • determination of colour coordinates on transparent and opaque samples
