Points a, b and x, y are reference marks at midpoint of test specimen edges. Sandwiches must not be stacked, as this may restrict movement of the plastic between the papers. Shorter reconditioning times may be used if it can be shown that equivalent results are obtained. A negative value denotes shrinkage, and a positive value indicates expansion.
