PROPERTIES DATA - The properties listed in this booklet are average values based on<br />
laboratory and field test data from a number of sources. They are indicative only of the results<br />
obtained in such tests and should not be considered as guaranteed maximums or minimums.<br />
Materials must be tested under actual service conditions to determine their suitability for a<br />
particular purpose. All data represent the average of four or less tests unless otherwise noted. The<br />
secondary units (metric) used in this booklet are those of the 81 system.<br />
