Relates to a method of determining the dimensional change in the longitudinal and transverse directions, of plastics films and sheeting on heating. This method may be applied to plastics sheets, whether qualified as thermoshrinking or not.
Abstract
Overview
ISO 11501:1995 specifies a laboratory method for determining the dimensional change on heating of plastics film and sheeting (up to 1 mm thick). The test measures changes in the longitudinal (machine) and transverse directions after controlled heating on a kaolin bed in a circulating-air oven. The procedure applies to both thermoshrinking/thermoforming materials and non‑shrink films, and is used to express shrinkage or elongation as a percentage change in gauge length.
Key topics and requirements
- Scope: Films and sheets up to 1 mm thick; measurement of dimensional change in longitudinal and transverse directions.
- Specimens: Three specimens ~120 mm × 120 mm, cut from centre and sides, with samples taken at least 50 mm from sheet edges; conditioned per ISO 291 prior to testing.
- Apparatus:
- Circulating-air oven with minimum six air changes per hour; oven temperature controlled to keep test assembly within ±2 °C (±1 °C if specified temperature
