Applies to optical fibre amplifiers (OFA) using active fibres, containing rare-earth dopants, presently commercially available.Establishes uniform requirements for accurate and reliable measurements, of the noise figure, as defined in 3.1.17 of IEC 61291-1, by means of the electricial spectrum analyzer (ESA) method.

ISO 9398-1:2002 defines the characteristics of flatwork ironing machines and gives the usual test methods for determining these characteristics with regard to machine capacity, power consumption and hourly productivity. It is applicable for use as a reference in the drafting of purchasing orders for flatwork ironing machines having a contact surface area greater than 0,25 m2. It does not cover…

ISO 9398-2:2002 defines the characteristics of batch drying tumblers and gives the usual test methods for these characteristics with regard to machine capacity, power consumption and productivity. It is applicable for use as a reference in the drafting of purchasing orders for batch drying tumblers whose net usable cage volume is greater than 160 dm3 (litres). It does not cover safety…

ISO 9398-3:2002 defines the characteristics of washing tunnels and gives the usual test methods for determining machine power consumption and hourly productivity. It is applicable for use as a reference in the drafting of purchasing orders for washing tunnels. It does not cover safety requirements (see ISO 10472-3).

ISO 9398-4:2002 defines the characteristics of washer-extractors and gives the usual test methods for these characteristics with regard to machine capacity, power and water consumption, and hourly productivity. It is applicable for use as a reference in the drafting of purchasing orders for washer-extractors whose net usable cage volume is greater than 60 dm (litres). It does not cover safety…

0. Introduction 0.1 This Standard sets forth the minimum features necessary to accommodate the boarding, transportation, and alighting phases of a trip taken on an accessible over-the-road bus (OTRB). This Standard incorporates the principle of current minimum requirements in recognition of (a) the masses of vehicles and the operating speeds (generally at an average speed exceeding 30 km/h (18.…

ISO/IEC 8825-3:2002 defines the Encoding Control Notation (ECN) used to specify encodings (of ASN.1 types) that differ from those provided by standardized encoding rules such as the Basic Encoding Rules (BER) and the Packed Encoding Rules (PER).

ISO/IEC 8824-1:2002 provides a notation called Abstract Syntax Notation One (ASN.1) for defining the syntax of information data. It defines a number of simple data types and specifies a notation for referencing these types and for specifying values of these types. The ASN.1 notations can be applied whenever it is necessary to define the abstract syntax of information without constraining in any…

ISO/IEC 8824-2:2002 provides the ASN.1 notation which allows information object classes as well as individual information objects and sets thereof to be defined and given reference names. An information object class defines the form of a conceptual table (an information object set) with one column for each field in the information object class, and with each complete row defining an information…

ISO/IEC 8824-4:2002 defines the provisions for parameterized reference names and parameterized assignments for data types which are useful for the designer when writing specifications where some aspects are left undefined at certain stages of the development to be filled in at a later stage to produce a complete definition of an abstract syntax.
