Talyrond 30 and 31 conform to the European Electromagnetic Compatibility regulations EN50081-1 and EN50082-1. Note: To allow for supply fluctuations, the preferred air pressure is 80-120lbf/in^2(5.4 to 8.1 bar) however where a constant supply pressure can be maintained, a minimum air pressure of 50lbf/in^2(3.4bar) is acceptable. Talyrond 30 Series instruments conform to all applicable requirements of BS EN 50081-1 (1992) and BS EN 50082-1 (1992) and comply with the requirements of the EMC Directive 89/336/EEC. Roundness, concentricity, eccentricity and run out measurements can be made with reference to Least Square Circle, Minimum Zone Circle, Maximum Inscribed Circle or Minimum Circumscribed Circle, flatness and square ness to Least Squares and Minimum Zone.
