BS 6365:2008

This standard BS 6365:2008 Specification for precision vernier depth gauges is classified in these ICS categories:

• 17.040.30 Measuring instruments

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 depth gauges. it applies to metric depth gauges that measure from zero up to 600 mm using a main scale and vernier scale graduated to read to 0.02 mm. It also applies to imperial depth gauges that measure from zero up to 24 in using a main scale and vernier scale graduated to read to 0.001 in.

NOTE Attention is drawn to the fact that the imperial dimensions are not necessarily direct conversions of the metric dimensions. For instance, the vernier division of 0.02 mm marked on the metric gauge corresponds to a 0.001 in vernier division on the imperial gauge, whereas the actual conversion is 0.001 in = 0.0254 mm.

Annex A gives recommended minimum dimensions for the beam section, whilst methods of testing are specified in Annex B.
