5.1 Gloss measurements are used to qualify a raw material or finished product.

5.2 Sample preparation will effect the outcome of gloss readings. This practice will eliminate second surface reflection, and allow a more accurate gloss reading of the substrate.

5.3 Materials which require this preparation include the following: clear or translucent substrates, colored transparent substrates, and areas printed with clear, translucent, or transparent colored coatings.

1.1 This practice covers the method of sample preparation, prior to taking gloss measurements on a membrane switch overlay.

1.2 Typical applications include window display areas on a graphic overlay, and surface texture.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
