Taber Multi-Finger Scratch/Mar Tester

The TABER ® Multi-Finger Scratch / Mar Tester is used to measure the relative resistance or susceptibility of a material surface to scratching, marring, gouging, scraping, engraving and other similar physical damage that can’t be classified as ordinary wear.

The TABER ® Multi-Finger Scratch / Mar Tester is used to measure the relative resistance or susceptibility of a material surface to scratching, marring, gouging, scraping, engraving and other similar physical damage that can’t be classified as ordinary wear.

The Multi-Finger Scratch / Mar Tester includes a pneumatically driven, move-able platform to which the test specimen is mounted. The platform moves in a linear fashion, and is operated by a control knob for single or multiple pass testing. An electronic timer displays the rate of speed, which can be controlled by reducing or increasing air pressure.

A gantry supports five independent splined-fingers, which provide a constant, vertical load on interchangeable scratch tips. The gantry system includes a handle to raise and lower the arms. In addition, five support rests are incorporated to allow one or more arms to be moved to an upright, rest position such that the arm does not contact the specimen during testing.

Individual weights of varying loads mount to the top of each arm finger to exert a standard force on the surface of the test material. Each instrument includes a weight set of 2N, 3N, 4N, 5N, 6N, 7N, 10N, 15N and 20N loads. Optional weights sets are also available consisting of either 4N, 8N, 9N, 13N or 8N, 13N, 18N weights. In additional, an optional weight of 25N or Precision Weight Kit to achieve 0.6N loads are available.

Although flat specimens up to 22mm thick are normally tested, the ‘free-floating’ arms fingers enable you test evaluate slightly contoured specimens provided they are rigid or adequately supported. A spring-loaded specimen holder is standard and can be mounted to the end or side of the moveable platform for greater flexibility. To mount contoured specimens, two specimen hold-down clamps are provided. An optional 5mm spacer set is available to raise the gantry to accommodate specimens that are greater than 22mm thick.

Taber Shear / Scratch Tester

Tester to evaluate resistance to shearing, scratching, gouging, marring, scraping and engraving on a variety of flat, rigid specimens

Pdf Brochure Video

Taber Shear / Scratch Tester is a motorised instrument for testing the resistance to scratching of materials. A sample plate rotates while a conical diamond point is pressed on the sample plate. The relation between the depth of the scratch and the applied (pre-set) pressure indicates the hardness.

Complies with virtually all relevant international standards such as Normen:
ASTM C217 / C217M • DIN 53 799 • DIN 66 861-4 • EN 438-2 • EN 13310 • EN 14323 • EN 14565 • EN 14688 • 0096Z-SEC-A000 (Honda) • 7710Z-SCC-9000 (Honda) • ISO 4586-2 • ISO 15695 • JIS K 6902 • Terrazzo 90322-9E-1 • TSL 2105G (Toyota) • TSL 3610G (Toyota) • UNI 9428

TQC Pendulum Hardness Tester

Paints and varnishes - Pendulum damping test

Pdf Datasheet User Manual Video

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.
