Table 13.15. Tolerance for accelerated aging tests on different submitted samples when tests are
made in different laboratories each on 200 seeds (2-way test at 5% signiicance level). The toler-
ances are extracted from Table G1, column L, in Miles (1963) (from Table 15G, International Rules
for Seed Testing, ISTA, 2010).
