This British Standard specifies requirements for the construction, accuracy at the reference temperature of 20 °C and the protection of metric and imperial precision vernier height gauges which include a scriber for marking heights. The metric height gauges measure height up to a maximum of 1 000 mm using a main scale and vernier scale graduated to read to 0.02 mm. The imperial height gauges measure height up to a maximum of 48 in using a main scale and vernier scale graduated to read to 0.001 in.
NOTE 1 Attention is drawn to the fact that the metric dimensions are not necessarily direct conversions of the imperial dimensions. For instance, the vernier division of 0.02 mm marked on the metric height gauge corresponds to a 0.001 in vernier division on the imperial height gauge, whereas the actual conversion is 0.001 in = 0.0254 mm.
Requirements for setting blocks which might be supplied are also specified.
Methods of testing height gauges are specified in Annex A.
