JIS B 0641-1:2001 Geometrical Product Specifications (GPS) -- Inspection by measurement of workpieces and measuring equipment -- Part 1: Decision rules for proving conformance or nonconformance with specifications
This International Standard takes into account measurement uncertainty and specifies acceptance criteria for indicated tolerances for product characteristics or maximum permissible errors for measuring equipment characteristics. It also specifies how to handle cases where compliance with the specifications cannot be clearly determined, that is, when the measurement results are within the uncertainty range near the specification limits (see 3.23). This standard is the basic GPS standard (see TR B 0007), i.e. the standard developed by ISO No. TC 213, which includes specifications for a product (usually given in tolerance limits) and specifications for a measuring device (usually given in tolerance limits). Usually given as maximum permissible error.) Applies to specifications defined in standards that include. This standard also It may be applied to specifications other than those defined in relation to the GPS basic standard. This standard does not apply to inspections using limit gauges. Testing using limit gauges is within the scope of ISO/R 1938. Note: The corresponding international standards for this standard are shown below. The symbols representing the degree of correspondence are IDT (matched), MOD (modified), and NEQ (not equivalent) based on ISO/IEC Guide 21.
