This document specifies a laboratory test method for determining the biocidal/biostatic efficacy of single active substances or combinations thereof used in film preservatives in a coating against fungal growth. This document does not apply to coatings not susceptible to fungal growth. The test method comprises only active substances for film preservation, not the protection of the substrate itself, e.g. wood, which is dealt with in another standard. The test method is applicable for active substances used for wood and masonry coatings. It is not applicable to marine coatings.Safety, health and environmental aspects are not in the scope of this document.Determination of the performance of film preservatives in coatings by applying ageing procedures is not within the scope of this document.

This document specifies a measuring method for the characterization of rheological properties of structural adhesives using oscillatory rheometry. Moreover, the testing procedure can be applied to the reactive mixture of several components or the components of a reactive bonding paste material. The advantage of the method in comparison to rotational viscometry measurements lies in the separation of elastic and viscous material properties, thus allowing the defining of the viscoelastic properties. This enables more precise information concerning the flow behaviour of the materials, thereby resulting in a better understanding of their processing properties.The method described is particularly suitable for filled and paste-like adhesives. These are frequently processed using automated pump and application systems in industrial applications and will be set precisely considering their rheological properties. As the rheological behaviour of uncured adhesives is mostly independent of their properties in the cured state, the document can also serve for the examination of non-structural adhesives.
