Specifies the essential characteristics of household refrigerating appliances, factory-assembled and cooled by internal natural convection or forced air circulation, and establishes test methods for checking the characteristics. These are type tests, and because of this, when verification of the performance of a refrigerating appliance of a given type in relation to this standard is necessary, it…

ISO 5801:2007 deals with the determination of the performance of industrial fans of all types except those designed solely for air circulation e.g. ceiling fans and table fans. Estimates of uncertainty of measurement are provided and rules for the conversion, within specified limits, of test results for changes in speed, gas handled and, in the case of model tests, size, are given.

1. SCOPE 1.1 This Standard sets forth minimum requirements for emergency valves that are intended to be used for the control of flammable and combustible liquids which are handled at temperatures within the range of -40 ° to +50 °C. For the purpose of this Standard, flammable and combustible liquids mean gasoline, fuel oil, kerosene and diesel fuel, including gasoline with small amounts of…

ISO/IEC 29642:2007 specifies the mechanical, physical and optical characteristics of 120 mm rewritable optical disks with capacities of 8,55 Gbytes and 17,1 Gbytes. It specifies the quality of the recorded and unrecorded 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…

Provides elements for product conformity assessment. Critical defects on tools, devices and equipment for live working are not acceptable. Major defects on tools, devices and equipment for live working are likely to result in failure or in a significant reduction of functionality, while minor defects do not reduce significantly the functionality. This standard defines assessment methods for…

Defines the requirements and quality assessment procedures for the type SC-PC (floating duplex) fibre optic patch cord connector, standard terminated on multimode fibre type A1a and A1b. This edition updated to harmonise with the requirements from IEC 61753-1, the optical interface of IEC 61755-3-3 and the modal condition as specified in IEC 61300-1. The QC number that appears on the front cover…
