    Revision of D7767 - 11 Standard Test Method to Measure Volatiles from Radiation Curable Acrylate Monomers, Oligomers, and Blends and Thin Coatings Made from Them

    (What is a Work Item?)

    Active Standard: D7767 - 11

    Developed by Subcommittee: D01.21 | Committee D01 | Contact Staff Manager


    1. Rationale

    The changes reflected in this revision of D7767-11 are the result of changes agreed upon at the January joint meeting of D01.21 and D01.56. Most are simple wording changes, modifications to a definition or additional apparatus. The proposed changes are listed below: 1)Title change from to of 2)Rewrote definition of pigment. 3)Defined thin per EPA Method 24 definition. 4)Opening paragraph in Section 5 now explains why the method is important and who will use the data. 5)Added a required temperature measuring device to the definition of forced air oven. 6)Added dessicator as required apparatus. 7)Did not include filter paper as required appartus since any suitable mark will suffice to indicate positioning of the lid relative to the tip of the light guide (fiber). 8)I removed the 15-minute storage in a dessicator requirement in Section 9.7 as the delay needlessly extends the test time per sample, the values obtained for Processing Percent Volatiles tend to be very low so the error is comparatively large, and the results are not utilized in the actual calculation of the Total Percent Volatiles. 9) Changed wording from or to and in Section 10 header. 10) Indicated that the values shown in Tables 1 and 2 are examples only. 11)Title change; add Estimate to overcome B. Sinajon Negative from Oct. subcommittee ballot. 12)Note 7 was modifed to allow interferences to be accounted for in both Methods A and B.
