This document specifies the equipment and procedures for determining the coefficient of linear thermal expansion at sub-ambient temperatures (−196 °C to 25 °C), subject to the possible temperature limitation of the test specimens. It is not applicable to products which experience dimensional changes during the test due to the loss of hydration water or which undergo other phase changes.

This document specifies a test method for the determination of per cent recovery and non-recoverable creep compliance of bitumen and bituminous binders by means of Multiple Stress Creep and Recovery (MSCR) testing. The MSCR test is conducted using the Dynamic Shear Rheometer (DSR) in creep mode at a specified temperature. The per cent recovery at multiple stress levels is intended to determine the presence of elastic response and stress dependence of bituminous binders. The non-recoverable creep compliance at multiple stress levels is intended as an indicator for the sensitivity to permanent deformation and stress dependence of bituminous binders. This document is applicable to un-aged, aged, stabilised and recovered bituminous binders. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber). WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

This document specifies test methods for slate, carbonate slate, schist and schistose stone for discontinuous roofing and external cladding, as defined in 3.1, 3.2, and 3.3 of EN 12326-1:2014 and 3.1 of prEN 12326-3:2021, used for assembly into discontinuous roofs and external wall cladding. In this sense, when the test describes a slate, it could also be considered as carbonate slate.
