Abstract
Overview
ISO 17221:2014 - Plastics - Determination of image clarity (degree of sharpness of reflected or transmitted image) specifies an instrumental method to quantify the image clarity of plastic specimens. The standard measures the sharpness of an image either reflected from a flat specimen surface or transmitted through it. Image clarity is an optical parameter distinct from gloss and haze and is expressed as a percentage.
Key Topics and Requirements
- Scope: Applies only to flat plastic specimens; specimen size 30 × 30 mm to 150 × 150 mm and thickness
