Overview
ISO 2190:2016 specifies the reference method for determining the moisture content of granulated cork. This international standard is essential for ensuring consistent quality control and factory acceptance testing of granulated cork materials. By providing a precise and reproducible procedure, ISO 2190:2016 aids manufacturers and laboratories in accurately measuring moisture levels, which is crucial for cork’s physical properties and performance.
The standard outlines the weighing, drying, and reweighing steps required to calculate moisture content, emphasizing the use of specific laboratory apparatus and sampling techniques. This approach ensures that moisture content data can be reliably compared across different facilities and batches.
Key Topics
- Scope and Purpose: Defines a standardized reference method for moisture determination in granulated cork, ensuring consistency across industry applications.
- Sampling Requirements: Uses ISO 2067 for correct sampling procedures to obtain representative test specimens.
- Test Procedure:
- Use of a ventilated oven at (103 ± 2) °C.
- Careful weighing before and after drying until constant mass is reached.
- Drying performed in open containers with a height of approximately 50 mm.
- Apparatus Specifications:
- Balance with 0.01 g resolution.
- Desiccators with efficient desiccants (e.g., silica gel) to cool specimens after drying.
- Calculation Method: Defines a formula to express moisture content as a percentage based on the mass loss before and after drying.
- Results Reporting: Requires averaging multiple test specimens and documenting procedures, results, and any deviations in the test report.
Applications
The ISO 2190:2016 standard is widely applicable in:
- Quality Control in Cork Manufacturing: Ensures granulated cork meets moisture specifications necessary for further processing and application.
- Industrial Testing Laboratories: Provides a benchmark methodology for routine testing of cork moisture content.
- Research and Development: Facilitates consistent measurement in product development involving cork materials.
- Supply Chain Verification: Assists in verifying the moisture content of cork materials upon delivery or acceptance.
- Environmental and Material Performance Analysis: Critical in assessing moisture impact on cork's mechanical and thermal properties.
By adhering to ISO 2190:2016, stakeholders maintain product integrity, prevent performance degradation caused by moisture variability, and improve comparability of results globally.
