Planar angle measuring instruments include. surface angle measuring instruments, small angle measuring instruments and line angle measurement appliance.2 measurement reference equipmentNational plane angle measurement standards, is the national plane angle measuring instruments, the highest standards for the reproduction and preservation of plane angle Units and through the use of measuring instruments to the first-class measurement instrument delivery value. The national plane angle is based on the following Three parts. (1) goniometric reference device (surface angle); (2) small angle reference device; (3) circular indexing Device. 2.1 Angular reference device (surface angle) Surface angle measuring instruments refers to the use of multiple plane approach to the circumference of the circle indexing device, and Verification of this type of angle device measuring instruments. Goniometric reference device (surface angle) by the multi-tooth indexing station, dedicated comparison Multi-faceted prism and self-collimator. The positive polyhedron includes integral degree polyhedron (the number of working face can be whole) Except for the positive polyhedron of 360 °) and the non-fullness regular polyhedron (positive polyhedron whose number of face can not be divisible by 360 ° body). The metrology performance of the reference device. α = 360 °, U = 0.05 ", Δ = 0.1". Pass the value of the form there The following three kinds. 1) When verifying a first-equilateral polygon prism standard device, read it with a self-collimator. Measurement method using the method of permutation, Best measurement capability U = 0.05 ". 2) When verifying the first-class angle-measuring standard device, a positive polygon with special alignment is used as a paternity measuring instrument, Positioning or reading the instrument with the exception of the instrument equipped with self-collimator. Measurement method using the method of permutation, the best measurement Ability U = 0.05 ". 3) test first-class standard small-angle devices --- small laser angle gauge, multi-toothed indexing units given diagonal, The measurement method using multi-location averaging method, the best measurement capability U = 0.05 ". 2.2 small angle reference device Small angle measuring instruments refers to the measuring range of 0 ° ~ 5 ° angle measuring instruments. Small angle reference device by the laser small Angle measuring instrument, special-purpose optical angle gauge and turntable composition. Metering performance of the reference device. α = ± 1 °, U = 0.03 ", Δ0 = 0.03". Pass the formation of the value There are two main types. 1) test first-class optical angle gauge, with self-collimator and plane mirror as a positioning device, the measurement method used Direct measurement, the best measurement capability U = 0.06 ". 2) test first-class angle measurement standard equipment and first-class, second-class circular scale standard device subdivision error or a small angle ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 2057-2006_English be delivered?Answer: Upon your order, we will start to translate JJG 2057-2006_English as soon as possible, and keep you informed of the progress.
