WHAT PERFORMANCE LEVEL SHOULD YOUR CAB ACHIEVE?

ISEEE created the Performance Level Metric to help the machine buyer understand the relationship between the real-world work environment and the Performance Level needed to insure protection in that environment. 

Performance Level 1

Light to moderate dust conditions, below 3000 feet/1000 meters in altitude, maximum sustained winds 20 mph/32 km/h.

 

Performance Level 2

Moderate to heavy dust conditions, working with controlled respirable particulate i.e. silica, asbestos, arsenic etc., operating below 6000 feet/2000 meters in altitude, maximum sustained winds 30 mph/48 km/h.

 

Performance Level 3

Moderate to very heavy dust conditions, working with controlled respirable particulate i.e. silica, asbestos, arsenic etc., operating below 6000 feet/2000 meters in altitude. Extreme weather conditions, maximum sustained winds of 40 mph/64 km/h.

 

Performance Level 4 - High altitude

Moderate to heavy dust conditions, working with controlled respirable particulate i.e. silica, asbestos, arsenic etc., operating between 6000 feet/2000 meters and 10,500 feet/3,500 meters in altitude, maximum sustained winds 30 mph/48 km/h.

 

Performance Level 5 - Cabs used in vapor or toxic gas environments

Moderate to heavy dust conditions, working with controlled respirable particulate ie. silica, asbestos, arsenic etc., known toxic gases ie. ammonia, sulfur dioxide etc., operating below 6000 feet/2000 meters in altitude, maximum sustained winds 30 mph/48 km/h.
