History Comprehensive Abrasion Test
Decades ago a small company out of the USA produced a machine to test the abrasion resistance of inks and coatings on aluminium beverage cans. The device simulates the motion of a truck or train during shipping and is used for assessing the transit scuff resistance of printed cartons and book covers as well as cans.
The printed sheet is sandwiched between oblong blocks of polyurethane rubber. A plain or printed sheet of the same stock is placed in with it and then hydraulic rams push the blocks from the side in a wave motion to simulate transit vibration. At the end of the test, the print-to-print or the print-to-plain-paper can be examined for scuffing.
Production and service stopped
About 10 years ago the activities of the small company were ceased and the machine was no longer available. Neither were parts or service.
Why this Abrasion test?
Beverage cans often suffer from severe scuff and friction during transport. Typically foodstuff in damaged packaging is hard- if not impossible to sell to the consumer. A small scratch is enough to make the merchandise worthless. And it can be worse…
If the paint (or ink) does not survive the scuffing movements during transport and bare aluminium starts to scuff against bare aluminium a can may start to leak within minutes. Especially carbonated drinks will spray and spill over the entire consignment thus destroying more or less the a complete pallet.
The yearly costs of these damages are significant. Keeping in mind that more than 300 Billion cans are sold globally per annum.
Since the failure of the coating can have two causes testing has to be done at both paint makers end and at the side of the can maker / paint applicator.

The TQC Pendulum Hardness Tester has a lot of unique features that ease defining hardness by the König and/or Persoz method as described in ISO 1522. Both methods work on the principle that the damping time of a pendulum oscillating on a sample indicates the hardness.
The instrument has an easy menu-driven interface with jog dial. The automated electronic counting mechanism is not affected by reflections from the surrounding area. The water-level is located on the test specimen, rather than on the instrument’s base. Once the instrument is leveled further calibration is not required. The gas-spring supported transparent draft cover allows easy access to all parts of the instrument.
TQC’s Pendulum Hardness Tester is a modular system. The instrument itself can be used for both the König and- Persoz method. Both pendulums should be ordered separately. After placing the correct pendulum, switching between the two measuring methods only takes a push of a button. The Pendulum is positioned fully automatically by means of a stepper motor. Also the release of the Pendulum is automated through electro-magnetic system. The end of a test is indicated by a visual and acoustic signal.
The TQC Pendulum Hardness Tester base device is available as a 110VAC / 50/60Hz and a 230VAC / 50Hz model.
The TQC Impact Test is used to determine the impact resistivity and flexibility of coatings. The dual scale instrument is equipped with a special guidance which assures that the distance between each impact is always according to the standard. For correct positioning a spirit-level is built-in. Each Impact test comes as a complete set (instrument and accessoires) to perform a test according DIN/ISO 6272, ASTM D2794 and ASTM G14
Mandatory test in Qualicoat, QIB and GSB accredited laboratories.
TQC Machu Scratching Tool to perform a Machu test (corrosion test) with. Each tool is provided with a 1mm width cutter to cut the coating down to the metal, complying with ISO 17872.
Two models are available:
The TQC Machu Scratching Tool Basic is based on the CC2000 model. with a self positioning knife bracket to expose the substrate with a perpendicular cut through the coating.
The TQC Machu Scratching Tool Professional is based on the CC3000 model with adjustable cutting depth and two ball bearings to guide the cut. This guarantees reproducible results.
