BS EN 1303:2015 classifies cylinders for locks using an 8-digit coding system. A broadly similar classification system is used for other building hardware product standards. Each digit refers to a particular feature of the product measured against the standard\u2019s performance requirements.<\/p>\n\n\t<\/div>\n\n\n\n

\n\t\t\t\n\n

Four grades are identified as follows:
Grade 0:<\/strong> No corrosion requirement, no temperature requirement
Grade A:<\/strong> High corrosion resistance, no temperature requirement
Grade B:<\/strong> No corrosion requirement, temperature requirement from \u201325\u00b0C to +65\u00b0C
Grade C: <\/strong>High corrosion resistance, temperature requirement from \u201325\u00b0C to +65\u00b0C<\/p>\n\n\n\n

Note:<\/strong> No distinction is made between the inside and the outside of either the cylinder and\/or the door. On completion of the test, the cylinder must operate using a maximum 1.5 Nm torque on the key.<\/p>\n\n\t<\/div>\n\n\n\n
