In B1.14.1 Driving procedures and redrive checks   (page 41)  Line 10  “blows/25mm” should be “blows/250mm”

In B1.14.3 Set  (page 42) Last line   “penetration of 250mm”   should be “penetration of 25mm”

Purchasers will have different updates on these errors dependent upon their purchase timing.  It is intended that this note alerts all purchasers to the  problem errors and that it can be referred to when clarification is needed for Specification discussions.
