BioVinyl[TM] Bio-based Low-VOC 20 89 65 Shore A LVOC2 (1) Values from Teknor Apex-developed test for measuring all VOCs in excess of 2 ppm.
Note that from the analysis presented in Tables 1 and 2, the preferred functional forms for the change point analysis of the NOX, SO2, and VOC are, respectively, DNOX, DLSO2, and LVOC. However, for comparison purposes, we present the results for the other possible functional forms in Table 3 as well.
Given the single change point of 1970 obtained by modeling DLVOC as a level shift in differenced series, we let the prechange point analyses of the VOC and LVOC series prior to 1969 reported in Tables 1 and 2 speak for themselves.
