2. Scratch hardness - Wikipedia

   en.wikipedia.org/wiki/Scratch_hardness

   Scratch hardness test or scratch test refers to any of a number of methods of measuring scratch hardness. Resistance to abrasion is less affected by surface variations than indentation methods. Scratch hardness is measured with a sclerometer. [1] Attempting to scratch a surface to test a material is a very old technique. [2]

3. Skin allergy test - Wikipedia

   en.wikipedia.org/wiki/Skin_allergy_test

   Skin scratch test: a deep dermic scratch is performed with help of the blunt bottom of a lancet. [3] Intradermic test: a tiny quantity of allergen is injected under the dermis with a hypodermic syringe. Skin scrape Test: a superficial scrape is performed with help of the back of a needle to remove the superficial layer of the epidermis. [4]

4. Anti-scratch coating - Wikipedia

   en.wikipedia.org/wiki/Anti-scratch_coating

   Anti-scratch coating is a type of protective coating or film applied to an object's surface for mitigation against scratches. Scratches are small surface-level cuts left on a surface following interaction with a sharper object. Anti-scratch coatings provide scratch resistances by containing tiny microscopic materials with scratch-resistant ...

5. Paint adhesion testing - Wikipedia

   en.wikipedia.org/wiki/Paint_adhesion_testing

   The cross-cut test is a method for determining the resistance of paints and coatings to separation from substrates by utilizing a tool to cut a right-angle lattice pattern into the coating, penetrating to the substrate. A quick pass/fail test can be accomplished through this method.

6. Scratch test (disambiguation) - Wikipedia

   en.wikipedia.org/wiki/Scratch_test_(disambiguation)

   A Scratch test may refer to: The skin allergy test used in the medical diagnosis of allergies; Scratch hardness tests, such as Mohs scale of mineral hardness, used to measure the scratch resistance of various minerals; Liver scratch test, used by medical professionals to ascertain the location and size of a patient's liver during a physical ...

7. Sclerometer - Wikipedia

   en.wikipedia.org/wiki/Sclerometer

   The Turner-Sclerometer test consists of measuring the amount of load required to make a scratch. [1] [2] In test a weighted diamond point is drawn, once forward and once backward, over the smooth surface of the material to be tested. The hardness number is the weight in grams required to produce a standard scratch.

8. Built-in self-test - Wikipedia

   en.wikipedia.org/wiki/Built-in_self-test

   Memory built-in self-test (mBIST) - e.g. with the Marinescu algorithm [2] Logic built-in self-test (LBIST) Analog and mixed-signal built-in self-test (AMBIST) Continuous built-in self-test (CBIST, C-BIT) Event-driven built-in self-test, such as the BIST done to an aircraft's systems after the aircraft lands. Periodic built-in self-test (C-BIT/P ...

9. Eddy-current testing - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_testing

   Variations in the electrical conductivity and magnetic permeability of the test object, and the presence of defects causes a change in eddy current and a corresponding change in phase and amplitude that can be detected by measuring the impedance changes in the coil, which is a telltale sign of the presence of defects.
