Materials and articles in contact with food stuffs - Test method for the resistance to microwave heating of ceramic, glass, glass-ceramic or plastics cookware

This European Standard specifies a method for the determination of the resistance to microwave heating of cookware made of ceramic, glass, glass-ceramic or plastics.
It is applicable to articles that are intended for multiple re-use in a microwave oven. It is not applicable to articles, particularly those made from plastics, which are intended to be discarded after one use.

Werkstoffe und Gegenstände in Kontakt mit Lebensmitteln - Prüfverfahren für die Beständigkeit von Kochgeschirr aus Keramik, Glas, Glaskeramik oder Kunststoff bei Erhitzung in der Mikrowelle

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Widerstandsfähigkeit von Kochgeschirr aus Keramik, Glas, Glaskeramik oder Kunststoff gegen Mikrowellenerhitzung bei Erhitzung in der Mikrowelle fest.
Die Norm gilt für Gegenstände, die zum mehrmaligen Gebrauch in einem Mikrowellengerät vorgesehen sind. Auf Wegwerf-Gegenstände, die nur einmalig benutzt werden, ist die Norm nicht anwendbar, was speziell für Gegenstände aus Kunststoff zutrifft.

Overview

EN 15284:2007 is a European Standard developed by CEN that specifies a test method to determine the resistance to microwave heating of cookware made from ceramic, glass, glass-ceramic, or plastics materials. This standard is designed for cookware and kitchenware articles that are intended for multiple re-use in microwave ovens. It establishes procedures to ensure such materials remain safe and effective when subjected to microwave energy, preventing damage to both the cookware and the microwave appliance during regular use.

This testing method is not intended for disposable plastic containers or articles meant for single-use applications.

Key Topics

• Test Methodology: EN 15284:2007 outlines a standardized procedure for subjecting cookware items to microwave heating for both short and long durations, simulating typical reheating and cooking cycles found in domestic microwave ovens.
• Scope of Materials: The standard covers ceramic, glass, glass-ceramic, and plastics cookware designed for repeated microwave use.
• Simulated Use Conditions:
  • Articles are tested empty to assess performance under thermal stress.
  • Porous ceramics and plastics are prepared to mimic real-use conditions, such as water absorption.
• Safety and Suitability Criteria:
  • Excludes articles that could damage microwave ovens (e.g., items with metallic decoration or high porosity).
  • Handles must not exceed safe temperature thresholds (56°C for ceramic, glass, or glass-ceramic; 60°C for plastics) after short-period microwave heating.
  • Articles are inspected for cracking, crazing, scaling, discoloration, deformation, melting, charring, and suitability for re-use.
• Reporting Requirements: Clear guidance is given on what should be included in a test report, promoting transparency for manufacturers and users.

Applications

EN 15284:2007 is applicable in a variety of contexts where ensuring the safe, repeated use of microwave-safe cookware is essential:

• Cookware Manufacturers: Enables producers of ceramic, glass, glass-ceramic, and plastic cookware to demonstrate compliance with safety regulations for products marketed as microwave-safe.
• Quality Assurance and Compliance Testing: Provides laboratories and quality control departments a consistent methodology for evaluating resistance to microwave heating, supporting product claims and regulatory compliance.
• Retail and Consumer Trust: Retailers can confidently supply kitchenware that has been tested according to a recognized European standard, enhancing customer confidence in microwave-safe claims.
• Regulatory Bodies: Serves as a reference for food-contact materials regulations, ensuring that products on the market do not pose hazard risks for end users or damage common household appliances.
• Product Development: Assists R&D teams in designing innovative microwave-compatible products by offering clear criteria for safety and durability.

Related Standards

For comprehensive evaluation of kitchenware and materials in contact with foodstuffs, the following standards are commonly referenced alongside EN 15284:2007:

• EN ISO 13732-1: Ergonomics of the thermal environment - Methods for the assessment of human responses to contact with surfaces - Part 1: Hot surfaces
• EN 12875-2: Mechanical dishwashing resistance of utensils - Part 2: Inspection of non-metallic articles

These related standards provide methodologies for surface temperature testing relevant to user safety and for evaluating the longevity of non-metallic articles in repeated-use scenarios.

---

Adopting EN 15284:2007 ensures that microwave-safe cookware withstands repeated use, protecting consumers and appliances while fostering trust in food-contact materials. Compliance with this standard is a mark of quality and safety in the European cookware market.
