EN 1104 Paper and Board Thermal Stability Testing
The EN 1104 standard is specifically designed to evaluate the thermal stability of paper and board materials. This testing method is crucial for ensuring that packaging and printing substrates do not degrade under heat stress, thereby maintaining their integrity and functionality over time. The procedure involves subjecting samples to a controlled temperature environment while monitoring changes in physical properties such as mass loss or color change.
The importance of thermal stability cannot be overstated, especially in industries where materials are exposed to varying temperatures during processing or storage. For instance, in the food industry, packaging must retain its structural integrity and barrier properties even after being subjected to heat treatments like pasteurization. Similarly, in printing applications, paper must withstand high drying temperatures without losing strength or appearance.
EN 1104 specifies a method for determining the thermal stability of paper and board materials by measuring their mass loss when exposed to specified temperature ranges over defined time periods. This helps manufacturers ensure that their products meet both regulatory requirements and customer expectations regarding performance under heat stress conditions.
The test procedure begins with careful sample preparation, which involves cutting specimens from sheets or rolls according to predetermined dimensions outlined in the standard. Samples are then weighed accurately before being placed into an oven where they undergo controlled heating at specified temperatures and durations.
| Temperature Range | Time Duration | Mass Loss Threshold |
|---|---|---|
| 105°C ± 2°C | 4 hours | <3% mass loss |
| 120°C ± 2°C | 6 hours | <5% mass loss |
After exposure to these conditions, the samples are removed from the oven and allowed to cool down. They are then weighed again to calculate any changes in weight due to evaporation or decomposition during heating.
The results provide valuable insights into how well the paper or board material maintains its physical properties after being subjected to specified temperature exposures. Compliance with this standard ensures that products perform reliably across various environmental conditions, enhancing both product quality and customer satisfaction.
Applied Standards
The EN 1104 standard is widely recognized in Europe for its stringent requirements on paper and board thermal stability. It specifies a method for determining the mass loss of these materials when exposed to specific temperature ranges over defined periods.
| Standard | Description |
|---|---|
| EN 1104:2018 | Determination of thermal stability of paper and board by mass loss after heating |
The standard defines the test conditions, including temperature ranges (105°C to 120°C), time durations (4 hours at 105°C; 6 hours at 120°C) and acceptable limits for mass loss. Compliance with these parameters ensures that paper and board products maintain their structural integrity and functionality under heat stress.
Implementing EN 1104 testing provides several benefits, including enhanced reliability of packaging materials in demanding applications such as food processing or high-temperature drying processes used in manufacturing industries. By adhering to this standard, companies can demonstrate their commitment to quality control and regulatory compliance.
