Ahlstrom Quality Assurance Review

Each statement is attached to the exact material, source, method and decision stage.

A verification worksheet, not a performance calculator

Four inputs determine whether a data point travels

This static worksheet exposes the checks behind a quality review. It does not calculate a pass result, predict device performance or replace the buyer's controlled test.

01

Material identity

Record product family, exact grade, composition or fiber system, construction and current document revision. A family name alone cannot carry a grade-specific value.

02

Property and unit

Name the property precisely: basis weight, caliper, absorbency, wicking, air permeability, pressure drop, retention or another stated measure. Preserve its unit and direction.

03

Method and specimen

Capture conditioning, sample geometry, apparatus or named standard, test direction, pretreatment and the specimen actually tested. Different constructions may not be comparable.

04

Decision stage

Mark whether the evidence supports document screening, bench comparison, converted prototype, pilot run or production release. Passing one stage does not automatically release the next.

Evidence-control scenarios

Common failure modes and their conservative correction

These are reproducible review patterns, not customer success claims. They show where a quality record can be misapplied and what information restores a defensible boundary.

Grade transfer

One pad grade's thickness is copied to another

Failure: a search result or older table is treated as a family specification.

Correction: retrieve the current exact-grade document, retain the unit and method, and verify incoming or prototype material against written criteria.

System transfer

Filter-medium data becomes a finished-filter promise

Failure: media behavior is quoted without pleating, seals, housing, loading or operating environment.

Correction: use the media record for screening, then test the converted element and system with a method that represents service conditions.

Device transfer

An IVD pad property becomes a diagnostic claim

Failure: wicking or release information is interpreted as assay sensitivity, specificity or accuracy.

Correction: keep the pad evidence at component level and establish completed-assay performance through the developer's validation protocol.

Certificate transfer

A generic badge is shown without product scope

Failure: issuer, site, product, standard, validity and legal status are omitted.

Correction: withhold the badge until a current document can be matched to the exact subject and claim.

Lot transfer

A development sample is treated as production release

Failure: a bench observation is used without a production-lot sampling plan or acceptance limits.

Correction: define the release stage, test frequency, sample selection and disposition for out-of-limit results.

Application transfer

A medical substrate becomes a finished-device approval

Failure: component information is expanded into sterility, clinical safety or regulatory authorization.

Correction: identify material-only evidence and leave device controls, sterilization compatibility and intended-use validation with the finished-device maker.

Request a quality evidence review

Send the source, not just the claim

Include the material family and grade, document title or revision, property and unit, test method, specimen description, intended application and decision stage. If your question concerns a completed filter, assay or medical device, state that explicitly so component-level evidence is not mistaken for system authorization.

No certificate, specification, sample availability, inventory, capacity, MOQ, lead time or diagnostic outcome is promised by submitting this form.
