1.Paragraph 126.96.36.199 This section requires revision to a) update the information on the temperature of immersion water in xenon arc exposure apparatus and b) correct the information on the temperature of the spray water which is confusing to an auditor checking the laboratory conditions specified for the test. The current wording on spray water temperature contains both non mandatory language (typically) and a specific tolerance required (21 +/-5oC). Revised as shown below. Delete the original text shown as cross-outs and add the underlined blue text. (This was balloted in 2014 with no negatives) 2.The editorial changes to Note 5 below have been made for clarification. (This was balloted in 2014 with no negatives) 3.Paragraph 6.2 - This paragraph is meant to describe qualitative criteria that can be applied through visual examination and handling of the sample after exposure. To determine loss of elongation, a tensiometer would be necessary, and a quantitative standard developed. It was determined that removing loss of elongation from the criteria would not impact the overall purpose or meaning of the requirement. 4.Tables 1 and 2- Although resistance to solar radiation (desert outdoor exposure) or to simulated solar radiation (xenon arc laboratory exposure) is required, this requirement is missing in Tables 1 and 2. Because the resistance is not to solar radiation alone, but also to other environmental conditions, including moisture and heat, it should be listed in the tables as Resistance to Environmental Conditions or to Simulated Environmental Conditions.
