This product does not have additional information.

Application of the device
Adhesion tester CM-1M is a device for measuring the adhesion value of bitumen pipe insulation and other insulating coatings which are based on bitumen. Adhesion tester CM-1M is a mechanical device which allows to determine the adhesion value of quality and quantity, by measuring the strength of sticking the bitumen insulation to the surface of the pipeline.
Adhesion tester of bitumen insulation allows user to take measurements during testing; planned inspections of steel structures and pipelines after their installation, and also after performing the repairs in order to identify defects during the application of the insulation, as well as for the subsequent monitoring of the quality of performed works. The device has been successfully used in the “field” and in the laboratory (workshop) conditions.

Design of the device
Structurally device is complied with the standards and it is consist of the system of rods, which are connected by calibrated spring. The device is installed on pre-prepared section of the pipeline (or metal construction) with a cut-out portion of the polymer coating and after turning the handle, will be applied the force with calibrated spring. During the load is applying, device measures the displacement of the rod, and after the value on the scale, which is installed on the device, converts into the shearing force and determines the adhesion value of the bituminous coating.

The adhesion value of the insulating coatings is characterized by shearing force for part of isolation with 1 cm2. Testing with adhesion tester CM-1M is perfoming in the following way: on the area 10 * 10 mm. of the covering insulation is performed the incision throughout its entire thickness. After that, the device is installed on the cover and abuts the blade to the end face of the formed area 10 * 10 mm. After turning the handle, the spring is compressed and applying the predetermined force on the knife, which transmits the shear deformation on the platform of cover. The strength of adhesion of the coating resists against the applied force. User should apply the force till occur the discontinuity (disruption) of coating area. The maximum value of testing is displayed on the scale of the device and fixed as the value of adhesion of the coating. The measurements are made at three points, which are located at least 50cm. from each other. The value of adhesion is the arithmetic average of three measurements.
