[Current]Cellulose-cement products, Part 2: Flat sheets
Specifies the characteristics, methods of control and test, and acceptance for fibre-cement flat sheets. It covers sheets intended for external applications such as cladding facades, curtain walls, soffits, lost casing, and the like, and sheets intended for internal use such as partitions, floors, ceilings, and the like, with a wide range of properties appropriate to the type of application. This Standard is identical with ISO 8336:1993.
