Overview
SIST EN ISO 20536:2018 is an international standard developed by CEN and ISO that specifies a test method for determining the amount of phenol in footwear and footwear components. Phenol is a critical substance that may be present in shoe materials due to manufacturing processes or chemical treatments. This standard ensures a consistent, reliable approach to testing, safeguarding both consumer safety and industry compliance. The method applies to all footwear components except metal parts.
By following SIST EN ISO 20536:2018, organizations can effectively monitor and control phenol content in their footwear products, supporting regulatory compliance and consumer trust across global markets.
Key Topics
- Phenol Determination: The standard outlines procedures to accurately measure phenol concentrations in various non-metal footwear materials, such as leather, textiles, and polymers.
- Sampling and Extraction: Guidance is given on sample selection, preparation, and extraction, utilizing a defined solvent mixture to ensure efficient and repeatable results.
- Analytical Technique: The method relies on advanced analytical techniques, namely gas chromatography-mass spectrometry (GC-MS), to identify and quantify phenol with high sensitivity.
- Calibration and Recovery: SIST EN ISO 20536:2018 details the use of internal standards, calibration curves, and recovery calculations for method validation and quality assurance.
- Reporting Requirements: The standard specifies the information to be included in test reports, ensuring clarity, traceability, and compliance documentation for regulatory or quality audits.
Applications
SIST EN ISO 20536:2018 is essential for a broad range of stakeholders in the footwear industry, including:
- Manufacturers and Suppliers: Ensuring that footwear products and raw materials meet safety standards and do not exceed acceptable phenol levels.
- Quality Control Laboratories: Performing routine monitoring and verification of footwear material safety using standardized test methods for phenol.
- Retailers and Brands: Demonstrating due diligence in product safety and regulatory compliance for consumer markets, both within the EU and internationally.
- Regulatory Authorities: Assessing product conformity to health and safety requirements regarding chemical substances in consumer goods.
- Certification Bodies: Using standardized phenol determination methods as part of broader certification or auditing processes in the footwear supply chain.
With phenol being a potential allergen and hazardous chemical, regular testing as per SIST EN ISO 20536:2018 supports safer products and minimizes risk exposure for end users.
Related Standards
For comprehensive footwear safety, SIST EN ISO 20536:2018 should be considered alongside related industry standards, including:
- ISO/TR 16178:2012: Defines a broader scope of critical substances possibly present in footwear and footwear components, providing a framework for which materials should be tested for phenol content.
- ISO 4787: Specifies general requirements for laboratory glassware and volumetric instruments, which are referenced for accurate sample handling and measurement.
- ISO 13528: Covers statistical methods for proficiency testing by interlaboratory comparisons, supporting the validation of phenol determination methods.
Together, these standards provide an integrated approach to chemical safety in footwear manufacturing and supply, forming part of responsible materials management and quality assurance strategies.
By implementing SIST EN ISO 20536:2018 for phenol determination in footwear, companies demonstrate commitment to chemical safety, regulatory compliance, and consumer protection, reinforcing confidence in their brands and products.
