These shall apply only when specified individually by the purchaser in the order. 1.3 The values stated in either inch-pound or SI (metric) units are to be regarded separately as standards. Within the text and tables the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 1.4 Unless the order specifies the applicable x201C;Mx201D; specification designation, the tires shall be furnished to the inch-pound units.
