1 Scope

This standard specifies the test method for a flat panel display using a polarizing film surface hardness. This standard applies to flat panel displays polarizing surface hardness testing.

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. Determination of film hardness ISO 15184 Paints and varnishes Pencil

3 Instrument

Other models test test pencil, sharpener, sandpaper shall comply with the provisions of ISO 15184, ISO 15184 may be the same as prescribed Instruments, test if the use of other types instruments to be recorded in the test report.

4 test sample

Test samples were cut from the measured polarizing film, the shape and size should meet the test requirements.

5 test procedure

5.1 Environmental conditions Unless otherwise specified, the test shall be carried out in the following environmental conditions. a) a temperature of 25 ℃ ± 5 ℃; b) Humidity RH50% ~ 80%. 5.2 Test Procedure Pencil test conditions, the sample holder shall comply with ISO 15184 requirements. Test speed was set to 0.5mm/s ~ 2mm/s, the sliding distance of 5mm ~ 10mm, the number of scratches less than five, the test load It is set to 4.9N ± 0.1N tested. Other models of test equipment operation in accordance with ISO 15184 regulations. If the test sample surface scratches not appear in the test area is not repeated tests, replace the high hardness of the pencil until at least 3mm long scratches up. If the test sample surface has more than 3mm long scratches occur, reduce the hardness test pencil repeated until more than 3mm long Scratches no longer occurs. To the surface of the test sample so that no 3mm and hardest pencil scratch hardness than the hardness of the test samples indicated. Parallel testing
