EN 1767 Products and Systems for the Protection and Repair of Concrete Structures - Test Methods - Infrared Analysis

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 1767 testing. This European standard describes a method for recording an infrared spectrum.

It applies to each component separately before applying to synthetic resin-based products and before mixing, especially in the case of two-component products. It also applies to emulsions of polymers (latex) to be mixed with hydraulic binders.

Organic molecules can vibrate at certain frequencies located in the infrared range. If infrared radiation encounters the molecule and the frequency of the radiation matches the vibrational frequency of the molecule, some of the radiation energy is absorbed.

Changing the wavelength of infrared radiation reveals a series of absorption bands. The set of absorption bands creates an infrared spectrum. This spectrum is characteristic for the chemical nature of a particular compound.

When the product is an emulsion or contains solvents, pigments and fillers, these components that will affect the spectrum analysis must be removed first. The test result is an infrared spectrum of the polymer binder. Details of the procedure that makes it possible to repeat the test under the same conditions should be reported.
