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/025 is a European Standardization Mandate titled "Ports and airports equipment". Ports and airports equipment There are 2 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.
This document describes the reference method, the Los Angeles test, used for type testing and in case of dispute (and an alternative method, the impact test) for determining the resistance to fragmentation of coarse aggregates (main text) and aggregates for railway ballast (Annex A). For other purposes, in particular factory production control, other methods are possible provided that an appropriate working relationship with the reference method has been established.
This document applies to natural, manufactured or recycled aggregates used in building and civil engineering.
Annex A describes a method for the determination of resistance to fragmentation of aggregates for railway ballast.
Annex B gives alternative narrow range classifications for the Los Angeles test and the impact test.
Annex C contains construction, operation and safety requirements for the impact tester.
Annex D describes a method for checking of the impact tester.
Annex E gives precision data.
Annex F contains a worked example of calculation of impact value SZ.
Annex G gives an alternative narrow range classification for the Los Angeles test of 16/32 mm recycled aggregates.
Annex H proposes an additional sieve for the evaluation of the Los Angeles test for railway ballast.
Annex A is normative and Annexes B to H are informative.
