ISO 5636-1 Roughness and Surface Testing
The ISO 5636-1 standard is a critical component in the evaluation of paper and cardboard packaging materials. This standard specifies methods for measuring the surface roughness of these materials, which directly impacts their performance during manufacturing processes as well as end-use applications.
Surface roughness can affect how easily materials fold, print on, or interact with other components within a package. For instance, rougher surfaces may make printing less clear and more prone to ink bleed, while smoother surfaces could lead to difficulties in gluing or sealing. Understanding the surface finish is thus essential for ensuring quality control at every stage of production.
Our laboratory adheres strictly to ISO 5636-1 guidelines when conducting roughness measurements. We employ advanced profilometers equipped with diamond stylus probes that can capture detailed profiles down to micron scales. This allows us to provide clients with accurate data on surface characteristics, which helps them optimize their processes and improve product performance.
The testing process begins by selecting appropriate samples representative of the type of packaging being evaluated. These samples are then cleaned according to specified procedures before being placed onto the profilometer for measurement. Once collected, raw profile data undergoes statistical analysis to determine key parameters such as arithmetic mean deviation (Ra), maximum height (Rz), and peak-to-valley distance.
After obtaining these measurements, our team interprets them within the context of industry best practices and relevant standards like ASTM D4303 or EN ISO 25178-1. This ensures that our findings are not only technically sound but also commercially viable for our clients' needs.
| Parameter | Description |
|---|---|
| Ra (Arithmetic Mean Deviation) | Averaged roughness value representing the average height of irregularities within a specified length. |
| Rz (Maximum Profile Height) | Height between the upper and lower limits of surface profile peaks and valleys over a given length. |
| Rt (Total Roughness) | Total height of all peaks and valleys within a specified range. |
