3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
NOTE Definitions of other terms that are related to weathering tests are found in Reference [2].
3.1control
material which is of similar composition and construction to the test material and which is exposed at the same time for comparison with the test material
Note 1 to entry: An example of the use of a control material would be when a formulation different from one currently being used is being evaluated. In that case, the control would be the plastic made with the original formulation.
