A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations. This British Standard is the UK implementation of EN 13834:2007+A1:2009. It supersedes BS EN 13834:2007 which is withdrawn. The start and finish of text introduced or altered by amendment is indicated in the text by tags. Tags indicating changes to CEN text carry the number of the CEN amendment. For example, text altered by CEN amendment A1 is indicated by ab. Subclause 6.1.7 introduces a method for determining thermal shock resistance which differs from the method defined in BS EN 1183:1997, Subclause 6.3. The UK committee considers that the test methods for determining thermal shock and thermal shock endurance contained within BS EN 1183:1997 are the most appropriate to use for evaluating the suitability of brittle materials, for example glass, glass-ceramics intended for use in ovens or as tableware. The committee would like to recommend that articles designated by suppliers as “ovenware”, “oven-proof ”, “oven-safe”, “oven to tableware ware” or any other similar description, which suggests that the articles can be safely used in an oven, should have a thermal shock endurance, t50, of not less than 150 ºC.
