Frequently Asked Questions
Which inspection checks are relevant to my carbon brush?
Start with the agreed drawing, material reference and application. Identify the dimensional, electrical and mechanical requirements that need verification, then confirm the applicable methods and acceptance criteria for the part.
Does every brush require the same test limits?
Use the limits specified for the relevant drawing, material and application. Do not transfer a generic resistance, hardness or load value to a different brush without an appropriate technical basis.
Can I request inspection records?
State the records required in the inquiry or purchase specification. Agree their scope, format and availability before ordering rather than assuming that every record or test is included.
How should a sample and later supply be compared?
Use the agreed specification, drawing revision and applicable acceptance checks as the reference. Record what was approved and confirm the verification method for later supply.
