Technical Description Model 202 EM
The Lacquer and Paint Testing Machine, Model 202 EM, is designed for testing the elongation and adhesion properties of coatings using the ERICHSEN Cupping Test. It features an electromotive drive, a laterally opened test head, and a digital display for cupping value acquisition. The machine is operated via a touch panel and includes a preselection counter for setting maximum cupping values.
This machine is used for rapid and accurate measurement of coatings on sheet metal specimens up to 1.5 mm thick. It provides insights into the suitability of coating materials for practical applications, with low cupping test values indicating potential issues with elongation stresses and substrate corrosion.
The machine is bench-mounted with a steel housing and a test cylinder. Specimens are clamped automatically, and test parameters such as speed and punch stop are set via the touch panel. The cupping process involves bilateral bending and stretching, with the test stopping when a crack is visible. The cupping depth is displayed digitally.
Optional accessories include a special test tool for narrower specimens and microscopes for observing the test procedure. A digital microscope with integrated lighting and a 10'' tablet is available for enhanced visual detection and documentation.
Dimensions: 470 mm (W) x 530 mm (D) x 410 mm (H). Weight: approx. 80 kg. Mains connection: 230 V, 50 Hz, 0.5 kW. Drawing speed: 2 to 60 mm/min.
Includes the basic machine with a test tool and operating instructions. Additional accessories are available for specific testing needs.
The machine complies with DIN EN ISO 1520 and other international standards. It is used by various organizations, including Deutsche Bahn AG and Deutsche Telekom AG, for quality control of coatings.
Specifications for cupping test values are provided for different coatings before and after ageing, with requirements varying by organization and application.

DEUTSCHE BAHN AG, TL 918 300 (Technical conditions of purchase for coating materials) The Cupping Test is conducted on 1 mm thick sheet metal specimen strip after 3 days drying. The cupping test is repeated after ageing at elevated temperature, on another part of the specimen. Ageing: The specimen panel is held at 100°C for 3 hours, and is then allowed to cool for 1 hour at room temperature. FEDERAL MINISTRY OF DEFENCE, VTL 7100-002 (Interim Technical Conditions of Purchase) The treatment of surfaces of accommodation equipment made of steel: Requirement: The Erichsen Cupping Test Value (DIN ISO...
