Table VIII-3. Classification of RMR by work.

RMR	Principal motion sites	Motion	Examples of works
0−0.5 0.5−1.0	hand	moving mechanically	call handling (seated) 0.4, data entry 0.5, gauge monitoring (seated) 0.5
		moving consciously	straightening (hammer tapping, 98 times/min) 0.9, vehicle driving 1.0
1.0−2.0 2.0−3.0	hand movement with some upper limb movement	hand movement with some forearm movement forearm	lathe work (pairing, 0.83 minutes/unit) 1.1, surveillance work (standing) 1.2, walking slowly on level ground (45 m/min) 1.5
		hand movement with some upper arm movement	walking (ordinary, 71 m/min) 2.1, concrete polishing (lightly) 2.0, circular saw work 2.5, stair walking (down, 50 m/min) 2.6
3.0−4.0	upper limb	normal movement	chinning grinder (grinding 150 kg parts, 6 min/unit) 3.0, riding bicycle (level ground, 170 m/min) 3.4, walking (fast, 95 m/min) 3.5
4.0−5.5		relatively big movement with power	riveting (1.3 /min) 4.2, filing (36 cm file, 150 times/min) 4.2, rough saw 5.0
5.5−6.5	whole body lifting, turning, pulling, pushing, throwing, moving up-and-down, scraping	normal movement	tapping (poking 7 kg, 16-20 times/min) 5.7, shoveling (6 kg, 18 times/min) 6.5, stair walking (up, 45 m/min) 6.5
6.5−8.0		relatively big movement with equal power especially momentary	hammering (6.8 kg, 26 times/min) 7.8
8.0−9.5			pile up (15 kg, 10 times/min) 9.0
10.0− 12.0	whole body (same as above)	physically strenuous work with a bit of leeway; may continue for sometime	pushing at full power 10.0 pickaxe (concrete bursts) 10.5 shovel (72 times/min.) 11.0
≥12.0	physically strenuous work such as construction work	concentrate on whole body movement and can tolerate only for less than one minute	hammering (4.5 kg, 29 times/min) 19.3
