（Have the regulation on Magnetic Material changed with the 52nd Edition?）**Q.**

Effective with the 52 Ed DGR, PI 902 for UN 2807 Magnetic Material was changed to PI 953. With the former PI 902 there was a statement which read: If the maximum field strength observed at a distance of 2.1m is less than 0.159A/m or there is no significant compass deflection (less than 0.5 degree), the article is not considered as a magnetized material. Now PI 953 does not carry this statement. Can this be interpreted that there is no longer a minimum benc Mar ? (30 Apr 11)

**A.**

DGR 3.9.2.2.1 and PI 953 clearly state that Magnetized Material is any material having a maximum magnetic field strength sufficient to cause a compass deflection of more than 2 degrees at a distance of 2.1 meter. There has been no change to the definition.
