Plan a Membrane Raw-Material Trial Order Around the Decision You Need
A trial order should answer a defined production question. Select the material, format and evaluation first, then agree the quantity and supply arrangement needed to make that decision.
Define the trial outcome
State whether the trial is for a new material, a format change or a replacement for an approved input. Identify the intended bituminous membrane construction and the purchasing decision that follows.
Avoid requesting several unlabelled samples and deciding the evaluation later. A specific question makes the comparison and the eventual order clearer.
Keep the candidate identifiable
Record product family, grade and dimensions. Release films need the relevant adhesive and release evaluation; reinforcement trials need the construction and technical requirements.
If multiple candidates are involved, use separate sample references and retain the approved production material as a comparison where appropriate. Do not merge their observations into one generic approval.

| Step | Define |
|---|---|
| Decision | What the trial must establish |
| Candidate | Product, grade and sample identity |
| Format | Width, core and usable roll quantity |
| Evaluation | Relevant process and acceptance criteria |
| Supply | Confirmed availability, packing and lead time |
| Conclusion | Approval scope and next purchase requirement |
Choose the usable trial format
Ask your production team for core, width, maximum roll mass and required run quantity. A small hand sample may support initial inspection but may not answer a full-line handling question.
Confirm trial-order availability, quantity and packing with Merily for the selected material. There is no universal minimum quantity implied by the trial plan.
Record the conclusion before scaling
Keep the actual input identity, process conditions and output evaluation together. State the approved scope and unresolved questions before moving to a production order.
Send Merily the intended use, selected candidate, trial format and destination. This connects the sample discussion to a practical supply request.

Tell us what you produce, the material you need and your required roll format. Include the quantity and destination port so we can prepare the product and packing details together.
Useful details: thickness or basis weight, width, roll length or weight, core, quantity and application. For release film, add coated side and release requirements.
Standard production: approximately 10 days for one 40-ft container order. Customized specifications: approximately 10–15 days. Confirm the schedule with the final order.
