For SDSS2 and 3, plates of 370 × 18 × 10 mm were sampled from the 10-mm- and 70-mm-thick plates. The load ratio (min. load over max. load) was R = 0.1, and a frequency from 0.08 to 5 Hz was used. However, most of the immersion tests were conducted at a frequency of 0.2 Hz up to 1 million cycles (approx. 58 days).
