Pants Types and Classes - What Is the Difference?
CLASS 0 to CLASS 3
EU Classification System For Chainsaw Protective Clothing EN381
The resistance of the clothing relative to the chain speed of the machine is measured using this special classification:
Class 0 -- 16 metres per second (36 mph) (3,150 feet per minute)
Class 1 -- 20 metres per second (45 mph) (3,937 feet per minute)
Class 2 -- 24 metres per second (54 mph) (4,724 feet per minute)
Class 3 -- 28 metres per second (63 mph) (5,512 feet per minute)
TYPE A and TYPE C
Leg protection is covered under the EN 381-5. The lowest allowable level for chainsaw pants is Class 1 (can resist cutting up to 20 m/s).
Type A – Covers the front of the legs and is intended for trained forestry workers or professional lumberjacks. It also provides arborists working at ground level with comfort and ease of movement, especially for heavy tasks.
Type C – All-around protection for the legs. Type C trousers are used by climbers and tree surgeons or professional arborists. Due to the extent of the protection, these can be quite warm for climbers to wear in hot weather,
