What to check before ordering a VDI reference plaque
| Question | Why it matters |
|---|---|
| Which grades do you need? | Metal and plastic plaques are available across VDI 12–45; confirm the exact grades your drawing calls out rather than ordering the full set by default. |
| Which material? | Metal plaques and plastic (PP/ABS/PC/PC+ABS) plaques read differently under light. Choose the material closest to your production resin. |
| Transparent parts? | Transparent materials need a dedicated plaque version to evaluate haze and light diffusion — ask before ordering if this applies to your part. |
| What is included on delivery? | Confirm plaque size, quantity, and any accompanying documentation (grade list, material spec) at the time of quote. |
| Lead time | Confirm current production and shipping lead time when you request your quote — it can vary by season and by material. |
This Ra figure matches the widely published Charmilles/Agie-derived VDI 3400 comparison chart, cross-checked against an independent EDM reference-standard supplier's published specification, not only against this site's own material. It is an indicative comparison value, not a licensed-standard quotation, gloss measurement, texture-depth conversion, guaranteed molded appearance, or contractual tolerance. If another document (for example a downloadable PDF) shows a different rounded figure, treat this page as the controlling reference until confirmed otherwise with your supplier.
