How do I know the trial roll is good enough to order bulk?
When four things pass: the properties meet the specification, the line runs it at speed, the pack or product passes its own test, and the documents match. Skipping the third is the usual mistake.
At a glance
Specification at a glance
| Check | Pass looks like | Cost of skipping |
|---|---|---|
| Fabric properties | Batch values inside spec | Rework or scrap |
| Line speed | Runs at target without breaks | Lower output |
| Finished product | Pack or product test passes | Recall risk |
| Documents | COA and declarations available | Customs or audit delay |
Why the finished product test matters
A fabric can pass every roll test and fail in the finished pack: a wipe dries out, a mask fogs, a gown tears at the seam. The trial is only finished when the product is tested, not when the roll is approved.
What to write down before ordering
The approved sample reference, the specification revision, the packing and the document list. Bulk orders drift when the approved sample is not the reference used at production.

Questions
Common questions
How long should a trial run?
Long enough to reach steady state on the line, usually 30 to 60 minutes of running, plus the finished product test.
Can bulk start before documents are ready?
It can, but shipment should not. Documents that are missing at the port are the most expensive kind.
What if the trial passes and bulk fails?
Compare batch records first. The usual cause is a line setting changed between trial and production.
