Wallpaper Samples
In general, a sample is a limited quantity of something which is intended to be similar to and represent a larger amount of that thing(s). The things could be countable objects such as individual items available as units for sale, or a material not countable as individual items. Samples of countable things are discussed in the article Sample. This article is intended to cover samples of material, in effect matter. Even though the word sample implies a smaller quantity taken from a larger amount, sometimes full specimens are called samples if they are taken for analysis, testing, or investigation like other samples. An act of obtaining a sample is called sampling, which can be done by a person or automatically. Samples of material can be taken or provided for testing, analysis, inspection, investigation, demonstration, or trial use. Sometimes, sampling may be continuously ongoing.
