Adult carrying a backpack
Defined standing height: 1.75 m; defined specimen.
A defined 1.75 m, 70 kg standing adult carrying a 5 kg backpack, for a combined mass of 75 kg. This is a comparison specimen, not a population average or load recommendation.
Defined examples — our methodology
The marked defined standing height is calibrated. Unmeasured illustration details are representative.
Adult in firefighting gear
Defined standing height: 1.78 m; defined specimen.
A defined 1.78 m, 75 kg standing adult wearing 18 kg of structural firefighting clothing and breathing equipment, for a combined mass of 93 kg. This is a comparison specimen, not a load limit.
