This document specifies requirements for certified reference materials (CRMs) of higher metrological order and the content of the supporting documentation and the calibration hierarchies as described in ISO 17511:2020, 5.2.1, 5.3.1, 5.4.1, 5.5.1, 5.6.1, 5.7.1. It is applicable to CRMs intended for use as either primary reference materials (PRMs), secondary calibrators or international conventional calibrators within calibration hierarchies appropriate for measurands used in laboratory medicine, or for applications as trueness controls. It also specifies requirements for determining the certified value of a CRM, including evaluation, and reporting of the assigned uncertainty.
This document is applicable primarily to CRMs with assigned property values where the property has a magnitude that can be expressed as a quantitative scalar number or ratio to a reference or refers to a counting scale as also described in ISO 17511:2020, Clause 1.
When a CRM includes multiple measurands, this document is applied to each of the certified quantity values present in the CRM.
Although intended to be applicable to producers of CRMs, this document is also useful for reference materials (RMs) that are not in conformity with the full metrological requirements of CRMs. For example, this document does not apply to an RM created by an in vitro diagnostic medical device (IVD MD) manufacturer for use as working calibrator or end-user calibrator within a calibration hierarchy traceable to a CRM, although some content can be useful in assessing its performance.

This document specifies methods for determining fracture toughness in terms of K, δ, J and R-curves for homogeneous metallic materials subjected to quasistatic loading. Specimens are notched, precracked by fatigue and tested under slowly increasing displacement. The fracture toughness is determined for individual specimens at or after the onset of ductile crack extension or at the onset of ductile crack instability or unstable crack extension. In cases where cracks grow in a stable manner under ductile tearing conditions, a resistance curve describing fracture toughness as a function of crack extension is measured. In some cases in the testing of ferritic materials, unstable crack extension can occur by cleavage or ductile crack initiation and growth, interrupted by cleavage extension. The fracture toughness at crack arrest is not covered by this document. Special testing requirements and analysis procedures are necessary when testing weldments, and these are described in ISO 15653 which is complementary to this document.
Statistical variability of the results strongly depends on the fracture type, for instance, fracture toughness associated with cleavage fracture in ferritic steels can show large variation. For applications that require high reliability, a statistical approach can be used to quantify the variability in fracture toughness in the ductile-to-brittle transition region, such as that given in ASTM E1921. However, it is not the purpose of this document to specify the number of tests to be carried out nor how the results of the tests are to be applied or interpreted.

This document specifies a method for determining the fire resistance of air transfer grilles (ATG).
It is applicable to air transfer grilles intended for installation in building components (typically walls, floors or ceilings). The orientation of the installation of the air transfer grille can be vertical or horizontal.
The closing mechanism of the air transfer grille can come from expansion of material and/or from any mechanical or electrical closing device.
This document is applicable to fire resistant or fire resistant and smoke control air transfer grilles.
An additional test configuration is valid for fire resistant or fire resistant and smoke control air transfer grilles in applications where flame impingement is a risk during open state from start of fire (see Annex A).
This document evaluates the behaviour of the air transfer grille when exposed to the heating curve described in EN 1363 1 and the standard pressure described in EN 1363 1. It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes under fire conditions. Such phenomena are only noted in describing the general behaviour of test specimens during the test.
The determination of the rate of leakage of smoke at ambient temperature or at 200 °C as an optional requirement for ATG with declared smoke control is specified in EN 1634 3.
This document is not applicable to the determination of the fire resistance of air transfer grilles that are used in ducts because ATG are considered as separating elements. The test method for ATG used in ducts is described in the corresponding duct standards.
This document is not applicable to the determination of the fire resistance of a fire damper or a fire barrier connected to a duct one or both sides, as an ATG is tested as a fire-separating element on its own. Fire dampers are tested according to EN 1366 2. Non-mechanical fire barriers are tested according to EN 1366 12.
This document is not applicable to the determination of the fire resistance of air transfer grilles in fire doors, shutters and openable windows as specified in EN 1634 1 and EN 1364 2, because the deformation of fire doors, shutters and openable windows in fire conditions differs from the deformation of flexible/rigid walls.
