Files
rfq-blank.csv: one row per requested filter item; keep quantities, references and open questions together.
sample-review-blank.csv: record the proposed sample, requirement, evidence and decision separately.
packaging-brief-blank.csv: connect product, packaging, artwork and quotation revisions.
worked-example.csv: a fictional incomplete sample-review entry; not an actual part, test, approved specification or commercial offer.

Use
Download a copy and open or import it as UTF-8 CSV in your spreadsheet app. Preserve part references as text. Complete unknown fields as unknown; do not treat blanks as compliance. Agree acceptance criteria for the actual application before approving a sample.
Separate dimensional, application, performance and packaging decisions. Identify the real decision-maker and date; do not use the example as an approval.
Your downloaded copies are local files. This page has no upload form. Do not send confidential drawings or customer data unless you intend to share them with a recipient.
The worksheets are planning aids, not a product standard, certification, vehicle fitment confirmation or contract. Consult the applicable vehicle instructions, agreed specification and qualified reviewers.
You may use the worksheets to prepare your own enquiries. For republication, translation or adaptation for distribution, contact lianchao@rz-inv.com to clarify permissions. No reciprocal link is required.
