46、in figure 1. It comprises:a) a level rigid plate whose surface roughness is not greater than 3,2 m (130 in) in accordance withISO 1302:1992. The plate shall contain an aperture to allow access for a micrometer probe;b) a micrometer accurate to within 2,5 m (98 in)with a probe whose contact area is a
