1 Scope This International Standard specifies a method for the determination of the adhesion/cohesion properties of sealants after cyclic exposure to heat and artificial light followed by a period of exposure to water at a defined temperature. NOTE The cyclic exposure of the test specimens to water and to radiation and heat is meant to simulate the exposure of sealants […]

1 Scope This International Standard specifies a horizontal method for the detection of Yersinia enterocolitica presumed to be pathogenic to human subjects. This International Standard is applicable to products intended for human consumption and the feeding of animals, and environmental samples in the area of food production and food handling. 2 Normative references The following referenced documents are indispensable for […]

1 Scope This part of ISO 5167 specifies the geometry and method of use (installation and operating conditions) of nozzles and Venturi nozzles when they are inserted in a conduit running full to determine the flowrate of the fluid flowing in the conduit. This part of ISO 5167 also provides background information for calculating the flowrate and is applicable in […]

1 Scope 1.1 This part of ISO 182 specifies a method for the determination of the thermal stability at elevated temperature of compounds and products based on vinyl chloride homopolymers and copolymers (in the following text abbreviated as PVC) which undergo dehydrochlorination (the evolution of hydrogen chloride). 1.2 The method may be used as a quality control test during manufacture […]

1 Scope This International Standard specifies the requirements that have to be implemented in future products that incorporate a digital interface, and service diagnostic software developed for these products. The Service Diagnostic Interface (SDI) requires the use of a PC (desktop or laptop) into which service diagnostic software can be loaded. A part of this PC software has to be […]

1 Scope This International Standard covers telescopic sticks and telescopic measuring sticks to be used for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and 1 500 V and above for d.c. The telescopic sticks are designed to accept attachments that meet appropriate live working standards and, together with these attachments, may […]

5.4 Terminals – Terminal block(s) – Protective earth terminal Terminals may be grouped in (a) terminal block(s) having adequate insulating properties and mechanical strength. In order to satisfy such requirements when choosing insulating materials for the terminal block(s), adequate testing of materials shall be taken into account. The material of which the terminal block is made shall be capable of […]

1 General 1 .1 Scope This part of IEC 61 81 1 is a blank detail specification applicable to electromechanical all-ornothing telecom relays of assessed quality. Relays according to this standard are provided for the operation in telecommunication applications. However, as electromechanical all-ornothing relays, they are also suitable for particular industrial and other applications. This standard selects from IEC 61 […]

1 General 1 .1 Scope This part of IEC 61 81 1 is a blank detail specification applicable to electromechanical allor-nothing telecom relays of assessed quality. Relays according to this standard are provided for operation in telecommunication applications. However, as electromechanical allor-nothing relays, they are also suitable for particular ndustrial and other applications. This standard selects from IEC 61 81 […]
