Description of BS 1054:1975 1975

This British Standard specifies requirements for comparators having magnification factors of 250 and over.

The type of comparator to which the requirements are primarily intended to apply is an instrument comprising a rigid stand supporting a measuring head over a work table.

The measuring head is provided with a measuring tip whose movements are amplified and indicated on a scale in metric units. The means of amplification may be mechanical, electrical, electronic, optical, fluid or pneumatic.



Design, construction and performance accuracy of comparators primarily comprising a rigid stand supporting a measuring head over a work table, the movements of the measuring tip being amplified by mechanical, electrical, electronic, optical, fluid or pneumatic means and indicated on a metric scale.
