Dyna-SPA
Dynamic Scratch & Abrasion Tester
Manufactured by Innowep
As the exclusive US distributor for Innowep products, Norman Tool offers the Dyna-SPA© tester. This is an all-in-one tester for dynamic scratch and abrasion simulation testing. With the long-term supplier experience in the automative industry since 1996, Innowep’s Dyna-SPA© tester has been selected to be the tester in BMW GS 97034-11 specification for variable shows shole test. Additionally, it can fulfill BMW GS 97034-8, -9 as well.
Damage to a surface due to abrasion, scratch, mar, scrape and punch is one of the main reasons for the disturbance of a product’s quality. In many real applications, deep scratch or severe abrasion occurs during a fast and high dynamic motion, e.g. a deep long scratch by a key on the exterior paint of a car. This high dynamic scratch occurs at a high speed up to 150 cm/s. Dyna-SPA® , is the only machine which can simulate the high dynamic scratch, punch and abrasion tests within one machine with freely programmable speed (up to 150 cm/s) and stroke (up to 120mm). It complies with over 50 international standards (ASTM/DIN/ISO)

Dyna -SPA® tester is designed to test either at surfaces or curved products, making it versatile to evaluate finished products of all sizes and all materials. A variety of optional test tips, test textiles, test media and sample clamps are provided to perform different types of abrasion, scratch, mar and punch tests. And it is also suitable for both wet and dry tests.
Dyna -SPA® tester is built with a horizontal piston rod driven by a pneumatic cylinder that moves in a linear motion, either one-direction or reciprocating. At the end of the cylinder is a movable assembly which allows the cylinder and the arm to move freely in the Z-direction. Therefore, the tip follows the shape and surface structure. The tip is mounted to the end of the piston rod and a dead weight is mounted on the top to generate a load in Z-direction onto the test sample. As the horizontal rod moves, the test tip raises or lowers vertically to follow the curvature of the test sample. In addition, the pillow block can be moved up and down, therefore the samples with a wide range of thicknesses can be tested.
Mode 1: One-Direction Mode
- Pneumatic system drives the tip wheel to the prepositioning point “2” to ensure the right velocity for the test.
- Then the tip is moving from point “2” with a certain stroke to point “3” at pre-defined speed.
- A pushup rod will lift the pneumatic cylinder to position “4” and reside back at the position “2” for the next cyclic linear motion.
- An opposite cycle from position “2” to “4”
Mode 2: Reciprocating Mode
- Pneumatic system drives the tip wheel to the prepositioning point “2” to
ensure the right velocity for the test. - Then the tip is moving from point “2” with a certain stroke to point “3”
at pre-defined speed. - A pushup rod will lift the pneumatic cylinder to position “4” and reside
back at the position “2” for the next cyclic linear motion. - An opposite cycle from position “2” to “4”
- Pneumatic system drives the tip wheel to the prepositioning
point “2” to ensure the right velocity for the test. - Then the tip is moving back and forth be- tween point “2” and “3” at pre-defined speed, the inward and outward speeds can be different.
Mode 3: Punch Test Mode
- Pneumatic cylinder is flipped 180◦.
- Then the punch tip is hitting the sample back and forth between point “1” and “2” at pre-defined speed.

Dyna -SPA® should be inspected, maintained and calibrated once a year. Some of the spare parts such as abradants are required to be replaced more frequently.
Dyna-SPA® tester has an adjustable program which enables the user to select the test mode, test speed, stroke length, test load and others. According to the test method, the test condition can be set up freely in the software.
TEST Methods:
Dyna-SPA® tester can perform various tests which comply with many ISO, ASTM, BS, GB/T standards. Please contact us for information on the test standards that can be performed by Dyna-SPA® to evaluate the resistance of a material surface to scratch, abrasion, mar, scrape and punch.
