PAS 54:2003 pdf download Specification for domestic ceramicware and glassware — Articles intended for contact with foodstuffs, and vases
1 Scope
This PAS specifies requirements for ceramicware and glassware intended primarily for home and domestic use.
This PAS acts as an umbrella PAS, referring to a variety of standards on ceramicware and glassware.
It covers the following:
— requirements for ceramicware, glassware and glass ceramicware:
• chemical composition;
• integrity of handle attachments;
• resistance to impact breakage in service;
• thermal shock endurance;
• metal marking;
• performance of vessels for pouring;
• handle and knob temperature;
• stability;
• water retention;
• metal release;
• metal release: lip/rim test.
— additional requirements for ceramicware:
• water absorption;
• crazing resistance;
• translucency.
— additional requirements for glassware:
• durability – hand washing;
• temper level.
— additional requirements for special applications:
• microwave usage;
• resistance to freezing and freezer to oven usage;
• freezer to microwave usage;
• dishwasher usage (durability);
— conformity marking.
NOTE This specification is not applicable to vitrified hotelware or corporate ware, for which there is a separate specification,BS 4034.

3 Terms and definitions
For the purposes of this PAS, the following terms and definitions apply.3.1 Ceramic
3.1.1
ceramic
inorganic non-metallic material made by firing a mixture of raw materials at high temperature. The firingtemperature is high enough to give the necessary strength to the article which is already shaped. but lowerthan the temperature which is necessary to achieve complete fusion of the mixture[BS EN 1900:1998,definition 3.3.1]
3,1.2
glazesubstance resulting from the melting or sintering of inorganic constituents and designed to form a surfacelayer which is fused, in one or more coats, and the firing temperature of which is higher than 500 °CNOTE Glazes can be opaque or transparent.
