This document specifies the nominal sizes of apertures for test sieves used for determination of particle size of aggregates. It applies to - test sieves of perforated metal plate having square holes of size from 4 mm and up to 125 mm; - test sieves of metal wire cloth having apertures sizes below 4 mm down to 0,063 mm.

This document specifies the scheme for the assessment and verification of constancy of performance (AVCP) of cements, including certification of constancy of performance. The document provides technical rules for factory production control, further testing of samples taken at the manufacturing plant (autocontrol testing) and assessment of the performance of the cement, initial inspection of the manufacturing plant and of factory production control, continuing surveillance, assessment and evaluation of factory production control and audit-testing of samples. It also provides rules for actions to be followed in the event of non-conformity and requirements for dispatching centres and for depots. In this document, the word "cement" is used to refer both to common cements as defined in EN 197-1 and to other cements and binders for which the relevant product specification standard makes reference to this document and which are submitted for certification. Such a cement is produced at a given factory and belongs to a particular type and a particular strength class, as defined and specified in the relevant product specification standard. The guidelines given in the Technical Report CEN/TR 14245 [4] contain information for the application of this document. NOTE The reason for having drafted this separate document is that the provisions it includes are applicable to different products covered by different European Standards.

This Standard is applicable to full size thermal insulating products and test specimens. This standard can also be applied to the individual layers of multi layered products. It specifies the equipment and procedures for determining the apparent overall density and the apparent core density under reference conditions.

This document specifies the equipment and test method for determining the effects of successive cycling from dry conditions at 20 °C to wet conditions at 20 °C on the mechanical properties and moisture content of the product. It is applicable to thermal insulating products. The propose of this document is to simulate the freeze–thaw effects on thermal insulating products which are frequently exposed to water and low temperature conditions, e.g. inverted roofs and unprotected ground insulation. The test is to be performed continuously using an automatic process of cycling between the specified conditions. This test method is not recommended for all thermal insulating products. If relevant, the product standards will state for which products this International Standard is applicable.

This document specifies requirements and appropriate test methods for slabs and cut-to-size products of agglomerated stone which are made for use as vanity and kitchen tops, or other similar use in furnishing (e.g. splash zone). NOTE "Agglomerated stones" are nowadays commercially termed "engineered-stones". This document does not cover secondary operations including site installation.
