National formulary a book of standards for certain pharmaceuticals and preparations not included in the U.S.P; revised every 5 years, and recognized as a book of official standards by the Pure Food and Drug Act of 1906. Abbreviated N.F.
Lever-type instrument for testing the flexibility and the adhesive properties of coatings when these are subjected to bending stresses. With 14 easy exchangeable mandrels (diameter 2 – 32 mm). Testing with the cylindrical mandrel bending tester determines the greatest cylinder diameter at which a coating will show cracking or flaking subsequent to bending. Model 266 S allows the testing of samples up to a width of 100 mm.
Inexpensive simply operating instrument. The stainless steel “comb” with tooth lengths varying by equal amounts is applied perpendicular to the wet film and the film thickness can be read off on the last tooth that made contact with the wet coating. 3 versions with measuring ranges 120/600/1200 microns. Also available is the Model 333-S: Large version acc. to BASF for road marking paint
A hardened and ground double wheel with an eccentric cam in the middle is rolled over a newly applied film. The wetting line on the middle cam is read off on a scale as wet film thickness. Total measuring range: 1500 microns, available in 8 different sub-ranges.
A robust instrument for gauging the degree of fineness-of-grind of liquid dispersions of pigments in the range 0 -15/25/50/100 microns. The substance is filled into the wedge-shaped grooves and drawn down with a blade. Rippling occurs at the point where pigments particles are bigger than the depth of the groove measured in microns.
To measure the density of coating materials and similar liquids. Robust and light weight design, made of black anodized aluminium or stainless steel. Available for 50 or 100 ml capacity. Can also be provided with certification from the official Bureau of Weights & Measures (EICHAMT) .
Paint testing machine, Erichsen cupping, up to 45 kN tensile force.
Lacquer and Paint Testing Machine, Model 202 EM, with electromotive drive, equipped with a laterally opened test head, test tool in accordance with DIN EN ISO 1520, electric installation for connecting the illumination of the microscope as well as a digital display for the acquisition of the ERICHSEN cupping value, with integrated preselection counter for setting the maximum cupping value required. The machine is operated via touch panel.
Application: This simple to operate Lacquer and Paint Testing Machine is used for rapid and accurate measurement of the elongation and adhesion properties of protective paints and other coatings of all types using the Erichsen Cupping Test in accordance with DIN EN ISO 1520, BS 3900 : Part E4, NF T 30-019, SIS 18 41 77 on sheet metal specimens up to 1.5 mm thick.
The ERICHSEN Cupping Test provides valuable information on the suitability of a coating material for application in practice. Low cupping test values mean that the coated product may not withstand elongation stresses arising, resulting in corrosion of the substrate. Model 202 EM is versatile and can be further enhanced by the various accessories available. The machine is a valuable tool for the quality control both for producers of paints and coating materials and for users.
Simple and inexpensive mechanical testing machine for ERICHSEN Cupping Test on painted or plastic coated sheet metal specimens up to 1.25 mm thick.
