Sample & Grade Evaluation: From Trials to Repeat Orders

A successful laboratory sample is the start of production qualification. We help you connect the material identity, trial conditions and acceptance record before moving into repeat orders. For calcium carbonate in a plastic formulation, the aim is a defined supply grade that your production team can evaluate consistently.

Turn Catalogue Differences into a Test Plan

A useful sample plan makes catalogue differences testable. XM-300 lists an average size of 1.5 μm and D97 of 3.8 μm. XM-400 carries a 1000-mesh designation and 98.5% purity, but its listed particle figures need units confirmed. The comparison starts by resolving that measurement basis.

Your trial and acceptance

Clear Production Gates

For a mineral-filled polymer, record dispersion and the mechanical or surface properties that matter. For a coating, record the specified appearance and film tests. Keep raw-powder measurements separate from finished-material results so the accepted outcome has a clear scope.

Decision controls

Selection Priorities

Check 01

Resolve incomplete data

Confirm units before comparing XM-400 particle figures with the μm-labelled XM-300 figures.

Check 02

Keep one clear control

Hold the important formulation and process variables steady while the candidate changes.

Check 03

Extend the trial deliberately

Assess a loading, carrier or process change as a separate decision with its own acceptance criteria.

Resolve the relevant gaps before extending a sample result into a supply decision.

From sample to supply

A Repeatable Purchase Record

The sample approval should produce a usable purchase specification: accepted model, critical limits and methods, required batch documents, packaging and trial-order scope. Sample quantity, dispatch arrangements and any testing support are discussed for the actual enquiry.
