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.
