Specifies dimensional, constructional and performance requirements for a range of spirit level vials - both cylindrical and circular - and describes a recommended method of testing. Also included is a series of recommended vial mounts.

1. This British Standard deals in detail with the various sizes and performance requirements for both precise and coarse spirit level vials. Ranges of parameters of spirit level vials for use in precision surveying, inspection and general levelling instruments are related to the sensitivity, and preferred sets of parameters for given sensitivities are indicated. In Appendix A is given a recommended method of testing vials and recommendations are made in Appendix B for preferred forms of mounting.
