M/BC/CEN/87/12 - CPD: masonry
Standardization request in the field of Construction products - masonry
This mandate concerns standardization in the field of construction products, specifically focusing on masonry. It involves the European Commission's request to European Standardization Organizations (ESOs), particularly CEN, to develop and harmonize standards applicable to masonry products and related construction practices. The mandate aims to support the Construction Products Directive (CPD) by ensuring consistent technical specifications and quality benchmarks across the masonry sector. The decision recorded under resolution CEN/BT 39/1987 addresses either the approval or disapproval of this standardization request.
Purpose
The mandate M/BC/CEN/87/12 relates to standardisation in the field of construction products, specifically focusing on masonry. It aims to facilitate the development and harmonisation of standards for masonry products and practices within the European Union to support regulatory compliance and enhance technical coherence across member states.
Standardisation request
This mandate requests the European Committee for Standardization (CEN) to develop and establish harmonised European standards covering various aspects of masonry construction products. The goal is to provide unified technical specifications and methods that address the properties, performance, and use of masonry materials in construction.
Expected deliverables
- Harmonised European standards for different types of masonry products.
- Technical specifications that ensure safety, quality, and reliability in masonry construction.
- Standards that align with the Construction Products Directive (CPD) requirements to facilitate free movement of masonry products within the internal market.
Context
This mandate was considered under resolution CEN/BT 39/1987, with a decision regarding its approval or disapproval. It fits within the broader framework of the Construction Products Directive, which seeks to harmonise technical standards for construction products to improve market transparency and regulatory consistency in the EU. The standardisation work supports regulatory objectives by providing a consistent basis for construction product assessment across member states.
The mandate covers standardisation work related to masonry within the field of construction products.

This European Standard specifies a method of determining the steady state water vapour permeability of autoclaved aerated concrete masonry units at the upper and lower part of the hygroscopic range. The test method is limited to products from which disc shaped specimens of uniform thickness can be made. No requirements are given for conditioning of the specimens. However, it will take longer for the test arrangement to reach equilibrium if the specimens are not in an approximately air dry condition at the start of the test.

This European Standard specifies procedures for the chemical analysis of aggregates. It specifies the reference procedures and, in certain cases, an alternative method which can be considered as giving equivalent results. If other methods are used it is necessary to show that they give results equivalentto those given by the reference methods. In cases of dispute, only the referenceprocedures shall be used. Unless otherwise stated, the test methods specified inthis European Standard may be used for factory production control, for audit tests or for type tests.

Frequently Asked Questions
A European Standardization Mandate is a formal request from the European Commission to the European Standardization Organizations (CEN, CENELEC, and ETSI) to develop European standards (ENs) in support of EU legislation and policies. Mandates are issued under Regulation (EU) No 1025/2012 and help ensure that products and services meet the essential requirements set out in EU directives and regulations.
M/BC/CEN/87/12 is a European Standardization Mandate titled "Standardization request in the field of Construction products - masonry". Standardization request in the field of Construction products - masonry There are 20 standards developed under this mandate.
Standards developed in response to a mandate and cited in the Official Journal of the European Union become "harmonized standards". Products manufactured in compliance with harmonized standards benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation, facilitating CE marking and market access across the European Economic Area.
