Conditioning, moisture grading & chain-of-custody records.
The workshop is part of the specification.
A material record follows the board from receipt to finished assembly. BirchFolio keeps those handoffs visible: incoming documentation, conditioning, machining and final inspection.
Specimen schedule
Nominal dimensions are reference examples. Inches, when selected, are rounded to three decimal places.
| Record | What to capture | Sample thickness | Acceptance context |
|---|---|---|---|
| Receipt | Supplier and batch | 18 mm | Match delivery documents |
| Conditioning | Climate and duration | 22 mm | Track stability over time |
| Moisture | Meter and correction | 24 mm | Measure several positions |
| Machining | Finished section | 20 mm | Check datum and tooling |
| Assembly | Adhesive and sequence | 30 mm | Retain trial-joint notes |
| Dispatch | Finish and protection | 12 mm | Record packing condition |
Kiln-dried is not a final moisture value
Kiln drying describes a process, not the moisture content on the day of machining. Storage and transport can change the result. Record ambient conditions and allow material to equilibrate before making close-fitting assemblies.
Use the meter as a documented instrument
Record the meter type, species setting and measurement depth. Take readings away from ends and obvious defects. Pin and pinless instruments sample differently; compare like with like and investigate inconsistent readings rather than averaging them away.
FSC claims belong to the transaction
When a project requires an FSC claim, verify the supplier’s applicable certificate and the exact claim on sales documentation. This library is not a certified supplier and makes no chain-of-custody claim for its illustrative specimens.
Retain a physical control sample
Keep a labelled offcut showing the agreed face, finish and edge treatment. A digital image cannot reliably communicate sheen, tactile quality or colour under the installation lighting. Record approval conditions alongside the retained sample.
