This International Standard specifies a method for the evaluation in aqueous medium of the ultimate biodegradability and, as additional information, the primary biodegradability and the total elimination from water, of organic compounds at a given concentration by aerobic microorganisms. The conditions described in this International Standard normally correspond to optimal conditions for allowing…

1.1 This International Standard specifies test methods for the determination of residual thiosulfate and other related chemicals in processed photographic materials. 1.2 This International Standard applies to silver halide/gelatin products that have been processed with a final thiosulfate fixing bath and a water wash. This International Standard does not apply to stabilised black-and-white…

This International Standard specifies methods for determining the thickness, bulk density, resilience, permanent linear change on heating, thermal conductivity, tensile strength and shot content of ceramic fibre products. It applies to ceramic fibre bulk, blankets, felts, mats, boards, papers and pre-formed shapes with the exception of products delivered in a wet state. The application of the…

1. Background 1.1 Environmental Management Systems and ISO 14001 An environmental management system (EMS) can be thought of as the application of general management principles to the enviro nmental issues associated with an organization's activities, products, and services. It provides a framework within which an organization can systematically identify and manage those elements…

1. SCOPE 1.1 This standard contains requirements for the design, manufacturing and marking for three types of means of containment used for the transportation of Class 6.2 dangerous goods (infectious substances), diagnostic specimens, biological products and biomedical waste. - Type 1A (high integrity) - Type 1B (routine) - Type 1C (waste). 1.2 This…

This International Standard specifies a method for assessing the potential toxicity of a test material to the growth of aerobic bacteria present in activated sludge. The inhibitory effect is restricted to those microorganisms capable of growth on the chosen organic test medium. This method gives information on inhibitory effects on the microorganisms over incubation periods up to 6 h. This method…

This International Standard defines the basic gesture commands for text editing with pen-based systems and defines the user actions required to have the system execute these commands. The feedback to the user when a gesture command has been correctly recognized is also defined. This International Standard does not define the user actions necessary for the input of characters.

This International Standard specifies the mechanical, physical and optical characteristics of a 120 mm optical disk to enable interchange of such disks. It specifies the quality of the recorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. The data can be written, read and overwritten many times using the phase…
