Description

Specifies requirements for three types of levels, viz. Type 1 which is usually made with a flat unrelieved base of hardened steel, Type 2 which usually has a cast iron body, and Type 3 which is a square block level that may be used for checking both flatness and squareness. Sensitivities of spirit level vials, design features, accuracy requirements and marking are specified and an appendix describes preferred test methods.

Scope

This standard specifies requirements for spirit levels for use in precision engineering. Although this standard deals specifically with spirit levels, it recognizes that levels operating on other principles perform a similar function, and it is recommended that such instruments should conform to the same general requirements for accuracy and performance of spirit levels, where applicable.
