Revetest® Scratch Tester (RST³)
Force and Displacement Sensors. However, it is feasible and possible to modify the test equipment and test conditions to conduct the test with lubrication or at elevated temperatures. Coating Damage Criteria and Scratch Atlas. It automatically synchronizes the recording of all sensor signals with the whole scratch image in perfect focus. Experimental Variables in Scratch Adhesion Testing. Under narrow circumstances, the test may be used for ceramic coatings on polymer substrates with due consideration of the differences in elastic modulus, ductility, and strength between the two types of materials.
Mechanical Stage and Displacement Control. No other units of measurement are included in this standard. Please first log in with a verified email before subscribing to alerts. The test method also describes the use of tangential force and acoustic emission signals as secondary test data to identify different coating damage levels.
Test specimens generally have a planar surface for testing, but cylinder geometries can also be tested with an appropriate fixture. Optical Analysis and Measurement.
Automatic detection of critical loads The critical adtm data is used to quantify the adhesive properties of different film-substrate combinations by using different sensors acoustic emission, penetration depth, friction force and video microscope observations.
Characterization of hard coatings — part I: The physical size of the test specimen is determined primarily by the capabilities and limits of the test equipment stage and fixturing.

Revetest® Scratch Tester (RST³) ::
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. High flexibility on scratch measurements The indenter tips in the indenter holder can be changed in an easy and quick way. The critical load data is used to quantify the adhesive properties of different film-substrate combinations by using different sensors acoustic emission, penetration depth, friction force and video microscope observations.
In this way the measurement curve can be analyzed exactly parallel to the scratch asrm on one page. Test Methodology and Experimental Control.
Test Frame and Force Application System. If the document is revised or amended, you will be notified by email. Test specimens generally have a planar surface for testing, but cylinder geometries can also be tested with an appropriate fixture. Measurements of the damage mechanisms in a asfm as a function of applied normal forces are useful to understand material-process-property relations; quantify and qualify the mechanical response of coating-substrate systems; assess coating durability; measure production quality; c164 support failure analysis.
The damage along the scratch track is microscopically assessed as a function of the applied force. Other Standards and References. However, reliable and reproducible test results require careful control of the test system configuration and testing parameters, detailed analysis of the coating damage features, and appropriate characterization of the properties and morphology of the coating and the substrate of the test specimens. The user only needs to set up some threshold values and start the automatic analysis of critical loads Lc.
ASTM C1624 – 05(2015)
By certifying our products accordingly, we can guarantee high-quality products and services in terms of safety, reliability, and environmental friendliness. Equipped with an easy-to-use software package, it is possible to perform scratch tests in a wide variety of testing modes, including simple scratch testing, advanced scratch testing with pre-scan and post-scanscratch map, scratch map by stage, user-defined scratch, etc.
This standard is also available to be included in Standards Subscriptions. You can download and open this file to your own computer but DRM prevents opening this file asym another computer, including a networked server. Tips of different diameters and angles are available.
It is the responsibility of the user of this standard to establish c1264 safety and health practices and determine the applicability of regulatory limitations prior to v1624. The damage along the scratch track is microscopically assessed as a function of the applied force.
Any specimen conditioning or environmental exposure shall be fully documented in the test report, describing in detail the exposure conditions temperature, atmosphere, pressures, chemistry, humidity, and so forththe length of time, and resulting changes in coating morphology, composition, and microstructure.
