Ergonomics is the design of work tasks to best suit the capabilities of workers. Ergonomics can help reduce or eliminate work-related musculoskeletal disorders (WMSDs) and other injuries and improve safety. Ergonomics programs provide guidelines for reducing workplace risk factors, which can lead to reduced workplace injuries.
In the Aggregate impact value test, a small portion of coarse aggregates having a size range between 10 to 12.5 mm, is confined in a 75 mm diameter cylindrical metal measure and subjected to 15 blows by a standard hammer weighing 13.5 to 14.0 kg falling freely from a height of 380±5.0 mm attached to the Impact testing machine (Bureau of Indian ...
