This document specifies two complementary test methods to assess the chemical reactivity of a pozzolanic or latent hydraulic cement constituent by measurements of heat of hydration (see Clause 5 and 8.3 Method A, Heat of Hydration) or bound water content (see Clause 5 and 8.4 Method B, Bound Water Content) of hydrated pastes composed of the cement constituent, calcium hydroxide, calcium carbonate, potassium sulfate, and potassium hydroxide cured at 40 °C for 72 h and 168 h (3 days and 7 days).
These two test methods do not distinguish between latent hydraulic and pozzolanic reactivity. Therefore, these methods are used for measuring the chemical reactivity of following cement constituents as specified under EN 197-1 and EN 197-5: S, D, P, Q, V, W and T.
These test methods are used in complement with the current specifications on cement constituent reactivity given by EN 197-1 and EN 197-5, i.e. the reactive silicon dioxide content measured according to EN 196-2 for cement constituents P, Q and V; the compressive strength of specified test mortars determined according to EN 196-1 for cement constituents W and T, and the pozzolanicity of pozzolanic cements according to EN 196-5 for CEM IV type cements according to EN 197-1.
The test methods are used for qualification purposes if the cement constituents are tested at the fineness of the intended use.
NOTE In case the test methods are used for purposes of comparison of intrinsic reactivity, cement constituents are tested at similar fineness, where possible.
The test methods are also used for testing other new constituents that are latent hydraulic or pozzolanic and that are not covered by EN 197-1 and EN 197-5. However, for such new constituents the validity of the underlying correlations with strength development have not been verified; in consequence the test results can only be used for informative and indicative purposes.
Furthermore, these test methods are used in manufacturing control of cement constituents for assessing their latent hydraulic or pozzolanic reactivity.

This document specifies a method for preparing samples of bitumen and bituminous binders in order to test their properties.

This document specifies a method for determining the consistency of bitumen and bituminous binders. The normal procedure is described for penetrations up to 330 mm × 0,1 mm at 25 °C. The maximum penetration that can be tested is 500 mm × 0,1 mm.

This document specifies a method for measuring the combined effects of heat and air on a thin moving film of bitumen or bituminous binder simulating the hardening which most bituminous binders undergo during mixing in an asphalt mixing plant.
The method described is not applicable to some modified binders or to those where the viscosity does not allow to provide a moving film. In some cases, the sample may creep out of the glass container and flow on the heating elements of the oven during testing. The method is suitable for other bituminous binders than paving grade bitumen, but the reference temperature might give excessive hardening that do not resemble real conditions during mixing at the plant. The method may not represent the hardening that occurs during mixing of warm mix binders.
The method is referred to as RTFOT, i.e. Rolling Thin Film Oven Test.
WARNING — 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 identify the hazards and assess the risks involved in performing this test method and to implement sufficient control measures to protect individual operators (and the environment). This includes appropriate safety and health practices and determination of the applicability of regulatory limitations prior to use.
If there is a likelihood of volatile components being present in a binder, this procedure should not be used. It should not be used for cutback bitumen or bituminous emulsions before these products have been stabilized, e.g. in accordance with EN 13074-2.

The purpose of this document is to specify the terminology applicable to bitumens and bituminous binders; therefore, this document contains only terms and definitions.

This document specifies the scheme for the assessment and verification of constancy of performance (AVCP) of ground granulated blast furnace slag, including certification of constancy of performance.
The document provides technical rules for the factory production control, further testing of samples taken at the manufacturing plant (autocontrol testing) and the assessment of the performance of the ground granulated blast furnace slag, initial inspection of the manufacturing plant and of the factory production control and audit-testing of samples. It also provides rules for actions to be followed in the event of non-conformity and the requirement for depots.
This document is linked with the Annex ZA of the European Standard covering ground granulated blast furnace slag, i.e. EN 15167-1:2006.

This document specifies the procedure for obtaining the non-steady-state chloride migration coefficient of specimens of hardened concrete at a specified age (see Annex A). The test procedure does not take into account any interaction of concrete with the saline solution over time. The test result is a durability indicator with respect to the resistance of the concrete investigated against chloride penetration.
The test procedure does not apply to concrete specimens with surface treatments such as silanes.
If the aggregate or any other embedded elements (such as metallic fibres or conducting particles) are electrically conductive, this will influence the magnitude of chloride migration. This fact is taken into account when establishing threshold values. It prevents comparison of chloride migration values between concretes if the aggregates induce a difference of half an order of magnitude (higher or lower) of chloride migration.

This International Standard specifies material requirements for preformed, solid vulcanized rubber structural gaskets in sealing and supporting applications for buildings.
NOTE Specifications for non-supporting gaskets are given in ISO 3934.
