Materials and articles in contact with foodstuffs - Test methods for thermal shock and thermal shock endurance

This European Standard specifies test methods for thermal shock and for thermal shock endurance for brittle materials, for instance glass, glass-ceramic and ceramics. Two test methods are described: Test method A is used for articles known to be sensitive to thermal shock; test method B is generally applicable. The test method to be applied depends on the intended use of the article and/or its thermal shock resistance.

Werkstoffe und Gegenstände in Kontakt mit Lebensmitteln - Prüfverfahren für Temperaturschock und Temperaturwechselbeständigkeit

Diese europäische Norm legt Prüfverfahren für Temperatuschock und Temperatur-wechselbestandigkeit spröder Werkstoffe fest, zum Beispiel für Glas, Glas- keramik und Keramik. Zwei Verfahren werden Beschrieben: - Verfahren A wird verwendet für Artikel, von denen bekannt ist, dass sie empfindlich gegen schroffen Temperaturwechsel sind ; - Verfahren B ist allgemeine anwendbar. Die jeweils anzuwendende Prüfmethode hängt vom beabsichtigten Gebrauch eines Artikels und/oder von  seiner Temperaturwechselbeständigkeit.

Matériaux et objets en contact avec les denrées alimentaires- Méthodes d'essai pour le choc thermique et la résistance au choc thermique

La présente norme européenne spécifie des méthodes d'essai pour le choc thermique et la résistance au choc thermique applicable aux matériaux fragiles comme le verre, la vitrocéramique et la céramique. Elle décrit deux méthodes d'essai: La méthode d'essai A, utilisée dans le cas d'objets sensibles aux chocsthermiques; la méthode d'essai B, applicable à tous les cas. La méthode d'essai à appliquer est fonction de la destination de l'objet et/ou de sa résistance aux chocs thermiques.

EN 1183:1997 - Materials and articles in contact with foodstuffs - Test methods for thermal shock and thermal shock endurance

Overview

EN 1183:1997 is a CEN European Standard that specifies test methods for thermal shock and thermal shock endurance of brittle materials used in contact with foodstuffs - for example glass, glass‑ceramic and ceramics. The standard defines two complementary test methods: Test method A for articles known to be sensitive to thermal shock, and Test method B as a generally applicable procedure. The selection of method depends on the intended use of the article and its expected thermal shock resistance.

Key topics and requirements

  • Scope and applicability
    • Applies to brittle food-contact materials and finished articles where temperature changes may occur during normal use, washing or production.
  • Two test methods
    • Test method A: Intended for articles recognized as particularly sensitive to thermal shock (used when low resistance is expected).
    • Test method B: A more generally applicable method for routine testing and assessment.
  • Test selection criteria
    • Choice of method is driven by the article’s intended use, service conditions and anticipated thermal gradients.
  • Performance assessment
    • The standard provides a framework to determine whether an article resists cracking, crazing or fracture under defined thermal cycling or shock exposures.
  • Relevance to food contact safety
    • Focuses on mechanical integrity under temperature change to ensure safe continued use of food-contact articles.

Note: EN 1183:1997 describes methods and decision criteria but does not replace product-specific requirements or national regulations for food contact materials.

Applications

  • Quality control and batch testing of glassware, ceramic tableware, cookware, and glass‑ceramic products intended for food contact.
  • Product development and materials selection to improve resistance to thermal shock in new designs.
  • Failure analysis and root-cause investigation where thermal cycling is suspected to cause cracking.
  • Test laboratories performing conformity testing for manufacturers and retailers.
  • Regulatory and compliance teams assessing mechanical durability aspects of food-contact materials.

Who uses this standard

  • Manufacturers of glass, ceramic and glass‑ceramic food-contact articles
  • Test laboratories and certification bodies
  • Quality assurance and product engineers
  • Materials scientists and R&D teams
  • Importers, retailers and regulators concerned with consumer safety

Related standards

  • EN 1183:1997 complements other European and national standards covering overall safety and chemical migration of food-contact materials. Users should reference product-specific and food-safety regulations in addition to thermal shock testing.
