QUALITY CONTROL
These are some tests that our products are subjected previously to be sold.
THICKNESS
ISO 2360
Thickness of a coating applied to a metallic test piece is checked by means of electrial-current induction (Foucault).
GLOSS
ISO 2813
The glossmeter enables the light reflected on an enarmel surface to be calculated.
IMPACT
ISO 6272
Resistance to rapid deformation, gauged on the basis of the impact of a ball of 12.5 mm and weighting 1 Kg, dropped from varios heights.
ADHERENCE
ISO 2409
Adhesion of a coating to metal. by means of making several cuts in a grid formation using blades with varying degrees of separation.
BUCHHOLZ HARDNESS
ISO 2815
Penetration test performed on a film, using a metallic disk with a sharp tempered-steel edge positioned below a metallic block.
PERSOZ HARDNESS
ISO 1522
Calculation of the pendular hardness of a coating applied to a metallic test piece, using Persoz pendulums.
ERICHSEN CUPPUING
ISO 1520
Evaluation of the resistance of a coating to the removal of a metallic substrate when it is subjected to a gradual deformation through cupping in normalised conditions.
FLEXIBILITY
ISO 1519
Resistance of a coating to checking and/or separation, with the metallic substrate being bent around a cylindrical mandrel.
COLOUR
COLORIMETRO
Colour comparison using a spectrophotometer that measures a light spectrum ranging from 360 to 700 nm.
VISUAL COLOUR
Colour comparison using a camera equipped with three illuminants, namely D65, A and TL-84.
SURFACE ANALYSIS
VIDEO-MICROSCOPE
Analysis of the finish of a coating's application, using a video-microscope.
ACCELERATED AGEING
ISO 9227
Evaluation of the resistance of paint films to artifical ageing, which involves subjecting them to an agressive environment (saline mist).
EXPOSURE TO RADIATION (XENON)
ISO 16474
Evaluation of the resistance of paint films to exposure to artificial radiation.
EXPOSURE TO RADIATION (U.V.)
ISO 4892
Evaluation of the resistance of paint films to exposure to ultraviolet radiation.
GRANULOMETRIC ANALYSIS
LASER
Analysis of the size of the particles of the coating by a laser analyzer.
BAKING ANALYSIS
GRADIEN OVEN
Analysis of the baking coatings using a gradient oven with 45 temperature zones. (VULCANO 4545)
