M/BC/CEN/87/12 - CPD: masonry

This European Standard specifies a method for determining the level of performance of those organic coatings classified in prEN 845-1 and prEN 845-2 as type 2 applied as a protective system to zinc coated steel plate used in the fabrication of ancillary components for masonry.

This European Standard specifies a method of determining the bending tensile strength of aggregate concrete masonry units having a width less than 100 mm and a ratio of length to width greater than 10, in accordance with prEN 771-3.

This European Standard specifies a method for determining the in plane shear strength of horizontal bed joints in masonry incorporating sheet damp proof course material using a specimen tested in double shear with load applied perpendicular to the bed joints. Guidance is given on the preparation of the specimens, the conditioning required before testing, the testing machine, the method of test, the method of calculation and the contents of the test report.

This European standard specifies a method for determining the shear strength of the welds in prefabricated bed joint reinforcement.

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.

Amendments to tolerances of bar sieves.

This part of this European standard specifies the procedure for the determination of the flakiness index of aggregate and applies to aggregates of natural or artificial origin, including lightweight aggregates. The test procedure specified in this part of this European standard is not applicable to particle sizes less than 4 mm or greater than 80 mm.

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.
