6、aration of a Coriolis vibratory gyro specification. Itprovides a common meeting ground of terminology and practice for manufacturers and users. The user iscautioned not to over specify; only those parameters that are required to guarantee proper performance in thespecific application should be contr

7、olled. In general, the specification should contain only thoserequirements that can be verified by test or inspection. Parameters in addition to those given in this standardare not precluded.Part II is a compilation of recommended procedures for testing a Coriolis vibratory gyro. These procedures,in

8、cluding test conditions to be considered, are derived from those currently in use. For a specific application,the test procedure should reflect the requirements of the specification; therefore, not all tests outlined in thisstandard need be included, nor are additional tests precluded. In some cases

9、, alternative methods for measur-ing performance characteristics have been included or indicated.The intent is for the specification writer to extract the applicable test conditions and equipment requirementsfrom clause 11 for inclusion in the appropriate clauses listed under 6.5 of this standard. S

10、imilarly, it isintended that the writer extract the applicable test procedures from clause 12 for inclusion in the appropriateclauses listed under 6.6. Part II can also be used as a guide in the preparation of a separate Coriolis vibratorygyro test specification with appropriate clause numbering. In

11、 general, the intent is for the specification writerto ensure consistency and traceability between Part II test procedures and Part I requirements for perfor-mance, mechanical, electrical, environmental, reliability, and quality assurance. To that end, a test procedureshould not be listed in Part II

12、 unless a related requirement exists in Part I.Blank spaces in the text of this document permit the specification writer to insert specific information suchas parameter values and their tolerances, clause numbers, etc. Brackets are used to enclose alternativechoices of dimensional units, signs, axes
