This European Standard: - Gives methods and procedures for the assessment of the in-situ compressive strength of concrete in structural elements and precast concrete products. - Provides principles and guidance for establishing the relationships between test results from indirect test methods and the in-situ core strength. - Provides guidance for the assessment of the in-situ concrete compressive strength in structures or precast concrete products by indirect or combined methods. This European Standard does not include the following cases: - Assessment of a limited volume of concrete where localised actual in-situ strength is required. - Determination of a limited volume of concrete in the structure was constructed with concrete from a conforming population. - Where indirect methods are used without correlation to core strength, chemical disinfectant and antiseptic products that form a homogeneous, physically stable preparation when diluted with hard water or - in the case of ready-to-use-products - with water. Products can only be tested at a concentration of 80 % or less as some dilution is always produced by adding the test organisms and interfering substance. This European Standard applies to products that are used in the veterinary field i.e. in the breeding, husbandry, production, transport and disposal of all animals except when in the food chain following death and entry to the processing industry. This standard describes test methods for Bovine Enterovirus Type 1 (Enteric Cytopathogenic Orphan Virus ECBO) as the model virus for all applications, namely for disinfection of instruments and surfaces and post-contamination treatment of post-mortem rooms, kennels and farm animal accommodation. The selection of this model virus is based on : - the feasibility of establishing a method for virucidal testing ; - representation of a group of clinical important viruses ; - as high resistance to chemical and physical agents as other clinically important viruses in the veterinary field.
