IN BRIEF
Plywood samples
A sample approval is useful when it identifies both the material examined and the decision made. Give the sample a reference that can travel from the workshop trial to the order and receiving record.
- Identify the sample and the construction it represents.
- State which observations were actually approved.
- Ask how the supplied lot will be linked to the order.
UNDERSTAND THE DETAIL
Reference sample, trial sample and production sample: what changes?
A reference sample illustrates a proposed appearance or construction. A trial sample is the piece used in an identified evaluation. A production sample is taken from identified production material. Those roles may overlap, but the record should say which role the piece actually serves.
If a showroom swatch is used to discuss colour, do not silently treat it as proof of the next production lot. Ask how the offered material will match the accepted requirements and which production or shipment records will establish identity. Keep the physical sample code on any trial report.
- Reference stage
- Record the proposed construction and the appearance or feature being discussed.
- Trial stage
- Connect the tested piece to the method, drawing and result.
- Production stage
- Identify the lot represented and the scope of any production checks.
What should an approval email contain?
Identify the sample, accepted item revision and the specific decision. For example: “Sample S07, item C2 revision 3: the finished edge appearance is accepted against reference E2; dimensional inspection remains as specified in C2.” Tailor the statement to the real result and retain the supporting record.
Continue with keeping approvals current on repeat orders.
Give the sample a complete identity
Record the supplier sample code, date received, proposed item description and drawing revision. Photograph labels before the sample is cut. If several samples arrive together, separate them before processing so a successful trial cannot be attributed to the wrong construction.
Keep offcuts or companion pieces where practical and agreed. Mark the visible face and any tested location. A labelled reference is more useful than an unmarked piece left beside a machine, especially when the buyer, workshop and receiving team work in different locations.
Record the approval scope and any open points
Describe what was evaluated: appearance, a machined joint, a coating trial or a particular test. Record the method and result beside the agreed requirement. Approval of one finished face does not automatically approve every dimensional or performance characteristic of a future shipment.
When the purchase order is prepared, include the accepted sample reference and the final construction description. Ask the supplier to identify any difference between that sample and the offered production. Agree which lot or bundle references will appear on the packing information and inspection records.
WORKED BUYING EXAMPLE
Example: two similar samples, one successful trial
Illustrative planning example; values and quantities are not product specifications or quotations.
Sample S-A and sample S-B have similar faces but different recorded constructions. The workshop accepts the joint made from S-B.
Scroll horizontally to compare all columns.
| Item or observation | Record or compare | Next decision |
|---|---|---|
| Sample identity | S-B label and construction sheet. | Attach both to the approval record. |
| Trial scope | Joint drawing J3 and the observed fit. | State exactly what the trial accepted. |
| Order reference | Final item P2 linked to S-B and J3. | Request matching identity on production records. |
What this means for the order
The order should identify P2 and its accepted construction. A general instruction to supply the sample material leaves too much room for confusion when several trials have been discussed.
Keep these details with your inquiry
- Sample code, photographs and proposed construction.
- Trial method, drawing revision and raw observations.
- Accepted features and unresolved requirements.
- Order item, bundle identification and retained reference location.
Review the relevant product guide and prepare your inquiry files.
Questions buyers ask
Does a small sample prove the whole shipment is consistent?
It records the results for the piece evaluated. Agree production requirements and a receiving or inspection plan for the actual lot.
What if the proposed construction changes after approval?
List the changed fields and determine which observations need to be repeated. Issue a revised approval reference before ordering the alternative.
