Revetest® Scratch Tester (RST³) ::

Invalid and Censored Data. This standard is also available to be included in Standards Subscriptions. Specimen Flatness and Level. It automatically synchronizes the recording of all sensor signals with the whole scratch image in perfect focus.

Data Analysis and Output Software Optional. In this way the measurement curve can be analyzed exactly parallel to the scratch picture on one page. Such coatings may require different stylus geometries, loading rates, and ranges of applied normal force for usable, accurate, repeatable results.

Rather, the test method gives a quantitative engineering measurement of the practical extrinsic adhesion strength and damage resistance of the coating-substrate system as a function of applied normal force.

The physical size of the test specimen is determined primarily by the capabilities and limits of the test equipment stage and fixturing. Characterization of hard coatings — part I: Primary and Supplementary Measurements.

Specific levels of progressive damage are associated with increasing normal stylus forces. Stylus and Stylus Mounting. Historical Version s – view previous versions of standard.

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. Force and Displacement Sensors. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Measurements of the damage mechanisms in a coating 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; and support failure analysis. The critical load data c6124 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.

Any variations in stylus size and geometry and designated normal force ranges shall be reported. Test Frame and Force Application System. The damage along c124 scratch track is microscopically assessed as a function of the applied force. 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.

The test method also describes the use of tangential force and acoustic emission signals as secondary test data to identify different coating damage levels.

High flexibility on scratch measurements The indenter tips in the indenter holder can be changed in an easy and quick way.

Test Data and Statistics. Active view current version of standard. No other units of measurement are included in this standard. Coating Damage Criteria and Scratch Atlas. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Optical Analysis and Measurement. Specific levels of progressive damage are associated with increasing normal stylus forces. Commonly, the low comparative modulus of the polymer substrate means that the ceramic coating will generally tend to fail in bending through-thickness adhesive failure before cohesive failure in the coating itself. As the voice of the U. Anton Paar works closely with standardization organizations such as ISO, ASTM, DIN, and others in order to support our customers to meet the high requirements they have for their own products, especially in quality control, where standards are often essential.
