We have robust processes in place to keep up to date with changes to National technical specification notices and standards through our involvement with the Department for Transport, ORR, RSSB, British, European and International standards bodies. Any changes are built into our assessment processes and communicated to NCB assessors. NCB supports development of the International and UK conformity assessment industry by providing experts to rail related forums.
