This document specifies the characteristics of tab washers for flight control rods.
These tab washers are intended to immobilise the rod end in relation to the rod body, whilst allowing a
positional adjustment of 1/2 a turn.
This document specifies the “as-built” data used for demonstrating completion of the build process and conformity of the product to type design. This document defines the minimum set of information to be archived to serve as a complete representation of an organization’s as-built data.
This document specifies additional requirements to ISO/IEC 17021-1. The requirements contained in this document, when implemented, support the demonstration of competence, consistency and reliability by the bodies performing auditing and certification of an artificial intelligence management system (AIMS) according to ISO/IEC 42001 for organizations that provide, develop or use AI systems.
Certification of AIMS is a third-party conformity assessment activity (as described in ISO/IEC 17000:2020, 4.5), and bodies performing this activity are third-party conformity assessment bodies.
This document also provides the necessary information and confidence to customers about the way certification has been granted.
NOTE This document can be used as a criteria document for accreditation or peer assessment.
This part of EN 196 describes the method for the determination of the compressive and, optionally, the flexural strength of cement mortar. The method applies to common cements and to other cements and materials, the standards for which call up this method. It may not apply to other cement types that have, for example, a very short initial setting time.
The method is used for assessing whether the compressive strength of cement is in conformity with its specification and for validation testing of a CEN Standard sand, EN 196 1, or alternative compaction equipment.
This part of EN 196 describes the reference equipment and procedure and allows alternative compaction equipment and procedures to be used provided that they have been validated in accordance with the appropriate provisions in this document. In the event of a dispute, only the reference equipment and procedure are used.
This document specifies the apparatus and procedure for determining the effective alkali content of cements and other hydraulic binders. The method determines the effective alkali content after 28 days of hydration by extracting pore water from cement stone and determining the concentration of sodium and potassium (method A) or hydroxyl ions in the solution (method B).
This document describes the analytical procedures used to determine the content of tricalcium silicate (C3S), dicalcium silicate (C2S), tricalcium aluminate (C3A) and tetracalcium aluminoferrite (C4AF) of cement starting from a chemical analysis on cement. The method can be applied on all common cements as defined on EN 197-1.
This document also describes the calculation procedures for determining of tricalcium silicate (C3S), dicalcium silicate (C2S), aluminate (C3A) and tetracalcium aluminoferrite (C4AF) in the Portland cement clinker as defined in the EN 197-1.
In both cases, for cement and clinker, the calculation method is based on the Bogue method assuming each phase has a pure composition. This is a conventional method, whereby the actual mineralogical composition can differ from the results obtained using this method.
For the determination of the various chemical species of clinker, cement and basic-complexing residue (BCR) described in this document, the method is indicated in the relevant clause.
This document describes test methods (reference and alternative) applicable to cast test specimens for evaluating the Sulftate Resistance (SR characteristic) of cements. Sulfate resistance means that these binders can be used in concrete bodies submitted to sulfate attacks.
In these methods, the test is carried out under controlled exposure conditions using an increased concentration of sulfate solution. These test conditions are intended to accelerate external sulfate attack.
The reference test method is adapted from the modified SVA test method (German Institute for Building Technology (DIBt), Expert Committee (SVA)): “Testing the Sulfate Resistance of Cements with pozzolanic main constituents”. The modified SVA test method is listed in European Assessment Document – EAD 150007-01-0301, Annex C. This test method is appropriate for various binders, in particular those with pozzolanic main constituents.
The alternative test method is listed in European Assessment Document – EAD 150009-01-0301, Annex A. This test method is appropriate for CEM III/A cements.
This document describes a test method applicable to cast test specimens for evaluating the Sulfate
Resistance (SR characteristic) of cements. Sulfate resistance means that these binders can be used in
concrete bodies submitted to sulfate attacks. In these methods, the test is carried out under controlled
exposure conditions using a defined concentration of sulfate solution. The chosen test conditions are
intended to accelerate external sulfate attack.
This test method is appropriate in particular for CEM III/A cements and other various binders, in
particular those with pozzolanic main constituents. It is adapted from the CUR - NL - Civieltechnisch

This test method is listed in European Assessment Document - EAD 150004-00-0301, Annex B.
This document describes two equivalent test methods for determining the glass content in Granulated blast furnace Slag (GBS) as constituent for common cement as defined on EN 197-1.
Method A - Method of determining the glass content of GBS by X-ray diffraction.
Method B - Method of determining the glass content of GBS by polarized optical microscopy.
The glass content (or glassy/amorphous phase) in GBS is the fraction of the material that lacks a crystalline structure, having solidified rapidly from the melt in the form of amorphous glass.
It is usually expressed as a percentage (wt%) of the total slag.
In the absence of a product standard or a specification in the product standard, the constituent is tested at the fineness of the intended use.
Furthermore, these test methods are used in manufacturing control of cement constituents for assessing their conformity to the limit indicated in EN 197-1.
This document describes a method for the determination of whiteness and the colour of common cements and clinkers.
This method can be used to determine the whiteness of white cements defined in the EN 197-1.
This document does not apply to colour measurements on cement-based formulated products or cement-based products.
The method is based on the measurement of the CIE XYZ trichromatic coordinates and describes the mathematical procedure for converting these coordinates into the CIE 1976 (L*a*b*) colour space.
NOTE Although the possible values of the L* parameter range from 0 to 100, this document applies to the range between 70 and 100 (photopic vision).
