Supplier Quality Guidelines - Heinrich Huhn GmbH & Co.

are used for the same operation, 100 parts per cavity or tool are required. Reference gauges are to be agreed
upon separately.
The agreed upon first article samples must be shipped to HUHN’s order address along with all required
records in a separate package identified with a coloured label bearing the words “first article samples”.
Shipment of first article samples with incomplete documentation must be approved in advance in writing by
HUHN.
5.1.2 Standard Products
The supplier must submit a first article sample punctually before approval for series production is issued.
After the supplier has submitted parts during the developmental stage, he must initiate component approval
without delay.
The scope of the first article inspection report generally corresponds to the requirements for HUHN-specific
parts, although product-specific simplifications are possible, for example if approvals from our customer have
already been received by the supplier. However, these must be authorised by HUHN prior to first article
submission.
5.2 Approval
HUHN examines the first article inspection report for completeness and compliance with the specified
requirements.
Individual characteristics are double-checked if deemed necessary.
Incomplete test reports, and test reports which exhibit non-approved deviations, are not processed and are
returned to the supplier. This is taken into consideration in the supplier evaluation. If first article submission
has to be repeated through the fault of the supplier, the supplier may be invoiced for processing costs.
HUHN expects first article samples to fulfil all requirements.
If deviations which cannot be corrected on short notice should nevertheless become apparent during the
course of first article production, a written request for limited deviation approval, or a drawing or specification
change, must be submitted prior to first article submission.
The chances of receiving approval must be clarified by the supplier in advance.
Implemented corrections must be approved by resubmitting a new first article inspection report. Agreed upon
correction deadlines must be adhered to.
Component approval is issued by affixing the required signature to the included PSW or VDA cover sheet.
Approved deviations are recorded. The signed cover sheet is returned to the supplier.
The supplier is not authorised to ship series produced parts to HUHN without this approval.
6 Re-Qualification
In order to assure continued quality, the supplier must re-qualify the product/process once a year.
The scope of the re-qualification process must be coordinated with HUHN.
Re-qualification results must be submitted to HUHN of the supplier’s own accord.
If no shipments are received from the supplier for more than a year, the original approval issued by HUHN
expires.
The part must be re-qualified in this case. The supplier must submit a request for re-approval by means of first
article submission (see above).
