Overview
SIST EN 16662-3:2026 defines the requirements for production control-including self-monitoring and third-party surveillance-of supplementary grip devices (SGDs) for tyres used on passenger cars and light duty vehicles. Established under the authority of SIST, this standard is a critical part of the EN 16662 series, focusing on systematic audits and quality systems to ensure safe and compliant supplementary grip devices across all manufacturers. It supports harmonized market practices within the European automotive sector by specifying processes and documentation for both internal (self-control) and external (third-party) quality assurance.
Key Topics
-
Production Control Requirements
Manufacturers are required to implement continuous production control for supplementary grip devices. This involves regular product examinations, compliance checks with established requirements, and documentation of all quality control activities. Production control ensures consistent manufacturing quality across all product variants.
-
Initial and Periodic Testing
Products must undergo initial testing aligned with EN 16662-1 and prEN 16662-2 to verify they meet safety and performance criteria. Ongoing testing and monitoring are essential for maintaining these standards throughout production.
-
Third-Party Surveillance
Accredited inspection bodies must audit manufacturers at least every two years. This external oversight provides independent verification of factory production control, sampling, and test result review, ensuring compliance with all relevant requirements.
-
Documentation and Reporting
Complete documentation-including production audit results, test reports, and surveillance contracts-must be maintained. Negative audit outcomes must be reported immediately to authorities and corrective actions taken.
-
Handling Modifications
Any change to a product must be communicated to relevant bodies. If a modification impacts safety or performance, additional review or testing may be required before continued certification.

Practical Value
The implementation of SIST EN 16662-3:2026 ensures that only safe, reliable, and compliant supplementary grip devices reach consumers and road operators. Through a combination of internal controls and external audits, manufacturers can demonstrate consistent product quality while distributors and testing bodies benefit from clear standards and reporting structures. This not only enhances road safety but also simplifies compliance documentation across the automotive supply chain.
