Specifies materials, properties, basic design details, accuracy and finish of vernier callipers reading to 0.1 and 0.05 mm in sizes up to 1000 mm and to 0.02 mm in sizes up to 300 mm. An appendix gives notes on the testing of the more important features of the instruments. It does not apply to dial callipers but these callipers may comply except for read-out and indicating mechanism.
Scope
This standard specifies requirements for vernier callipers reading to 0,1 (1/10), 0,05 (1/20), and 0,02 (1/50) mm, and having measuring ranges as given in Table 1.
Requirements for materials and properties, basic design, accuracy and finish are also specified.
NOTE: Notes on methods for testing the more important features of vernier callipers are given in Appendix A. These notes are for guidance only and do not purport to be either recommended or mandatory methods of test.
Although dial callipers are not specified in this standard (see Preface), they should comply with all relevant requirements except those for the read-out and indicating mechanism.
