This document specifies the equipment to be used, the procedures to be applied and the requirements for sampling common cement and/or its constituent materials, representative of defined lots, for testing purposes. The same equipment and procedures can be used for other types of cement or materials; in some cases, modifications to the procedure are also permitted, provided that this document and/or the modifications are referenced in the relevant product standards. The provisions of this document are only applicable when samples of constituent of common cement are: a) required for evaluating the conformity of common cement or constituent of cement at the characteristics related to common cement, to cement constituents, to the release of dangerous substances to soil and ground water of common cement, and to environmental sustainability of common cement; or b) requested for checking a delivery or a lot with a standard, the provisions of a contract or the specification in an order. This document is applicable to the sampling of powders or bulk materials, whether they are: c) contained in silos; d) contained in bags, canisters, drums or any other packages; e) transported in bulk in road vehicles, railway wagons, ships, etc. NOTE The requirements of this document can also, by agreement between the parties, be followed for acceptance inspections for all non-standardized hydraulic binders.

 

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 specifies the terms, definitions, methodologies, and calculations that are required for the physical recycling and recovery of plastic waste. The document also defines the different types of physical recycling technologies used in the recovery and recycling of plastics waste sourced from post-industrial and post-consumer waste streams. The general requirements, process stages from “input “to “output” that should be considered in evaluating different types of physical recycling methodologies are described in the document which may be useful for any plastics waste processor or recycler. Further, this document gives guidance on the general process and quality requirements to be considered at all stages of the recovery process and provides general recommendations for inclusion in material standards, test standards and product specifications. This document provides guidelines for all types, technologies of physical recycling, currently in practice which are characterized by processes that include the selective dissolution, delamination, extraction or precipitation of plastic waste without intentional changes to its chemical structure. The process stages, requirements, recommendations, and terminology presented in this document are intended to be of general applicability.

 

This document specifies general requirements for the measurement of viruses in workplace air. This document complements the scope of EN 13098. The document provides guidelines for the assessment of workplace exposure to airborne viruses comprising the methodology for sampling as well as for analysis, which is applicable for both, active or inactive viruses, e.g. methods based on cell-culture or molecular biology. This document is not applicable for the measurement of other microorganisms than viruses and microbial compounds.

 

Applicable to test pieces cut from products of cellular materials. Useful for two purposes: a) studying the structure of cellular products in connection with their physical properties and their method of manufacture and b) ensuring product quality (quality assurance). Describes principle, apparatus, test piece and conditions, procedure and calculation and expression of the results. Three figures deliver the details for testing.

 

This document establishes a common basis for planning and design, area and space management, financial assessment, as well as a tool for benchmarking in the life cycle of the built asset. This document covers area and space measurement for existing owned or leased buildings as well as buildings in state of planning or development. This document establishes a framework to deal with area and space measurement to promote both the entire life cycle information requirements and the digital technologies used by the industry. In addition, it defines clear terms and definitions as well as methods for measuring horizontal areas and volumes in buildings and/or parts of buildings, independent of their function.

 

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.
