ISO 287 Moisture Content of Recycled Paper Samples
The measurement of moisture content in recycled paper samples is critical to ensuring product quality, compliance with environmental regulations, and the overall performance of recycled paper products. ISO 287:1996 establishes a standardized method for determining the moisture content in recycled paper using an oven-drying technique.
Understanding moisture content is essential because it directly impacts the paper's strength, tensile properties, and printability. Excess moisture can lead to reduced product quality, increased storage space requirements, and higher production costs due to drying time. Conversely, insufficient moisture may result in poor bonding between fibers during manufacturing processes.
The standard specifies that samples should be conditioned under specific temperature (23°C) and relative humidity (50%) for a minimum of 48 hours before testing. This conditioning ensures uniformity across different batches or lots of recycled paper, providing more accurate moisture content readings. During the test, samples are weighed accurately to at least three decimal places then dried in an oven set between 103°C and 105°C until constant weight is achieved.
Once dried, the sample is reweighed, allowing for precise calculation of its moisture content using the following formula:
- W₁: Initial mass of sample before drying.
- W₂: Mass of sample after drying to constant weight.
This testing method is widely used across various industries including packaging manufacturers, converters, and paper mills. By adhering strictly to ISO 287, companies can ensure consistent product quality while also meeting regulatory requirements set forth by authorities such as the European Union's Waste Framework Directive or similar national standards.
Implementing this test helps organizations maintain environmental responsibility by minimizing waste and optimizing resource use during production processes. It contributes significantly to reducing energy consumption associated with drying operations, thereby lowering carbon footprints for both manufacturers and end-users alike.

Environmental and Sustainability Contributions
- Promoting Efficient Resource Use: By accurately measuring moisture content, manufacturers can identify optimal drying temperatures reducing energy consumption associated with heating processes.
- Reducing Waste: Precise control over moisture levels helps prevent excessive water absorption during production which leads to better paper strength and reduced waste at the end of its lifecycle.
- Emissions Reduction: Lower drying temperatures required when maintaining optimal moisture content contribute significantly towards reducing greenhouse gas emissions from industrial operations.
- Enhancing Recycling Loop: Accurate moisture content measurements ensure that recycled fibers are not over-dried, thus preserving their quality and recyclability. This supports the circular economy by encouraging reuse rather than disposal of valuable materials.
