4 General requirements
4.1 Unit of measurement
In this standard, all linear dimensions, standard deviations and standard errors of the test piece are in millimeters (mm).
4.2 Inspection tools
The measuring instrument should have a resolution of 0.02mm or higher. Recommend to use micrometer, vernier caliper, coordinate measuring machine, three-dimensional scanning
Other inspection tools that meet the requirements of measurement accuracy can also be used.
4.3 Inspection sequence
During the inspection, priority should be given to the items specified in the inspection standards, and then other items that are of interest to users. In order to facilitate the assembly and disassembly of tools and inspection, the
Both parties agree to proceed in any order.
4.4 Inspection items
When additional inspection items are needed for acceptance purposes, the user can negotiate with the equipment manufacturer to determine these items.
Indeed proposed.
4.5 Process parameters
The equipment commitment conditions or requirements shall be met when processing test pieces. The forming of the test piece of the same manufacturing batch and the internal and external structure of the same test piece
The process parameters should be kept consistent, and the outer surface forming accuracy should not be improved by adjusting the process parameters to reduce the density.
