Preparing the specification

Separate functional fits from noncritical features. Define datums, size limits, geometric tolerances and the measurement method. Specify surface roughness only where function requires it, including the measurement standard and direction.

Before sending the RFQ

Highlight critical features and describe how the part will be inspected. Ask the supplier to confirm feasibility for the actual drawing.

Standards and tolerances

For linear and angular dimensions without individual tolerances, class m may be agreed during drawing review.

Can inspection documents be included?

Material certificates and dimensional inspection reports can be coordinated when requested. The inspection scope and documents are agreed for each order.

Apply this to your own project.

Share the drawing, quantity and specification you want to review.
