Ophthalmic optics. Contact lens care products. Microbiological requirements and test methods for products and regimens for hygienic management of contact lenses1 Scope This International Standard specifies two test methods for evaluating the antimicrobial activity of products to be marketed for contact lens disinfection by chemical means and for products that are part of a contact lens care regimen. This International Standard is not applicable to the hygienic management of trial lenses. NOTE General disinfection product standards are not applicable to contact lens care products, e. g. EN 1040: 1997 and EN

It offers guidance on areas such as chemical composition and mechanical properties

FM sound radio: Additional performance requirements

BS EN ISO 24373 specifies requirements for classification of solid wires and rods for fusion welding of copper and copper alloys

The present standard does not necessarily comply with Directive 94/9/EC

This European Standard applies to steel ball valves mainly used for industrial and general purpose applications

for use in aircraft

The range of application depends on the amount of total soluble salts in the water and on the performance characteristics (background count rate and counting efficiency) of the counter used
