System code	EN-PC-146-055-6-1-12.5-WB-25. Guidance for specification option: The maximum height stated under Partition height (see below) is for the fire resistance of the system to meet project requirements where EN compliance is required. The stated maximum height figure is the lower value between the cold state height, calculated structurally to a limiting deflection of L/240 @ 200 Pa and the fire state height, as outlined in accordance with EN 1364-1. BS-PC-146-055-6-1-12.5-WB-25. Guidance for specification option: The maximum height stated under Partition height (see below) is for the fire resistance of the system to meet project requirements where BS compliance (BS 476-22), is required and is accepted by the client, designers and building control. The stated maximum height figure is based on the maximum cold state height, calculated structurally to a limiting deflection of L/240 @ 200 Pa.
