ISO 393-4:1986 PDF Download

ISO 393-4:1986 is a standard that sets out the requirements for trapezoidal section sheets made from asbestos-cement. These sheets are primarily used for roofing and cladding purposes. The standard defines the specific requirements that these products must meet in order to ensure their quality and suitability for their intended applications.

In addition to specifying the requirements, the standard also outlines the test methods that can be used to assess whether a particular product meets these requirements. This helps to ensure that the sheets are manufactured to the specified standards and are safe for use. The standard also includes provisions for marking the products and sets out acceptance conditions that must be met for the sheets to be deemed acceptable.

It is worth noting that the standard does not apply to corrugated sheets, asymmetrical section corrugated sheets, or "short sheets" with corrugated or asymmetrical sections. These types of sheets are addressed in separate sections of ISO 393-4:1986.
