The largest source of ergonomics standards is ISO/TC 159, the main ergonomics committee. There are four sub committees which produce many ergonomics standards.

ISO/TC 159/SC 1 General ergonomics principles
ISO/TC 159/SC 3 Anthropometry and biomechanics
ISO/TC 159/SC 4 Ergonomics of human-system interaction
ISO/TC 159/SC 5 Ergonomics of the physical environment

The BSI has a specific webpage dedicated to its ergonomics standards.
