ISO 4593

Plastics — Film and sheeting — Determination of thickness by mechanical scanning

Testmaterialer

ISO 4593 applies to plastic films and sheets, including materials used in packaging, industrial applications, and consumer products. The standard ensures reliable thickness measurements for consistent product quality.

Testprosessen

The standard primarily uses micrometer measurements or mechanical displacement methods. The film or sheet is positioned between two flat surfaces under specified conditions, including pressure and test speed, to measure its thickness precisely.

Tolkning av testresultater

Test results reflect the film’s uniformity and quality. Deviations in thickness may indicate potential issues in production processes, affecting material performance and compliance with application-specific standards​.
