Figures 3.34 to 3.37 depending on the grade tested, several data points are possible for a given family depending on the test method used. These general indications are not necessarily representative of all the thermoplastic families and should be verified by consultation with the producer of the selected grades and by tests under operating conditions.

In Figure 4.3(a) we can see a broad difference between two grades tested under a light load (2-3 MPa). The third grade tested under 8.75 MPa is probably more creep resistant.

The problems of the CAP tests were analyzed in the same manner as were those in the textbooks. Table 3.6 contains a summary of the situations found in the test problems. Each of the CAP tests had a large number of test items 360 items on the third-grade test, 480 items on the sixth-grade test, and 468 items on the eighth-grade test. Of these, story problems accounted for roughly 30% of the third-grade test items and about 40% of the other two tests. 

Most of the story problems at all three levels could be distinguished by the situations depicted in them. In toto, over 80% of the items had unique situation classifications. All traditional items were classifiable by their embedded situations. Items not classifiable on the third-grade test were primarily of two types items requiring the student to count (e.g., What comes next ) and... 

Instead the grade stress is determined direetly by in-grade testing, and the link with elearwood values through the strength ratio has been broken.

Table VI also shows the relationship between the amount of hydrocarbon in the form of percent Ct and the relative fuse grade. The number of samples in Table VI is reduced from previous tables since many of the papers, because of their properties, were unable to withstand the abrasive fuse grade testing. For example, the sample with high levels of filler separated rather easily and pulled fibers from the surface, invalidating the test procedure. Even without these samples, however, a clear relationship between the amount of hydrocarbon on the surface, either in the form of rosin and rosin salts or lignin, is clearly related to the adhesion of the toner polymers to the paper surface. A least square fit of these data has a (relatively low) correlation coefficient of 0.85, and a slope of -0.8. Although the relationship may not be a linear one, it is clearly reasonable to presume that higher quantities of hydrocarbon on the surface of paper do prevent adequate adhesion of toner. This result corresponds with the previous work done by Borch(16) and also with results presented elsewhere in this symposium volume.

The mass of the test sample is 5000 10 g. The test sample required is shown in Table 2.9. The steel spheres used are similar in size and mass to the European CEN EN 1097-2 (2010) method. The number of revolutions is also the same but the number of steel spheres added to the drum depends on the size of the aggregate (grading) tested (see Table 2.9).

School information records also contain educational information such as grades, test scores, specializations, activities, and official letters about a student s status in school and records of individualized education programs. School information concerning schools attended, courses taken, attendance, awards conferred, and degrees earned are kept as well.
