The purpose of ISO/TR 28980:2007 is to explain the changes relating to power measurements in the revised editions of ISO 8980-1 and ISO 8980-2. In order to illustrate the issues raised, an inter-laboratory power measurement study was conducted on ten different lenses measured by nine organizations worldwide. Twenty-five focimeters of different types were used. The test lenses were spherically…

ISO 13584-501:2007 specifies the requirements for an ISO-registered reference dictionary for measuring instruments with their properties and domains of values. ISO 13584-501:2007 also establishes and specifies the behaviour of a registration authority whose role is to develop, maintain and update this ISO-registered reference dictionary for measuring instruments. These measuring instruments…

Applies to television broadcast receivers, sound broadcast receivers and associated equipment intended for use in the residential, commercial and light industrial environment. Describes the methods of measurement and specified limits applicable to sound and television receivers and to associated equipment with regard to their immunity characteristics to disturbing signals. This standard is also…

ISO 140-18:2006 specifies a laboratory method of measurement of the impact sound insulation of roofs, roof/ceiling systems and skylights excited by artificial rainfall. The results obtained can be used for assessing the noise to be produced by rainfall on a given building element in the room or space below. The results can also be used to compare rainfall sound insulation capabilities of building…

ISO 871:2006 specifies a laboratory method for determining the flash-ignition temperature and spontaneous-ignition temperature of plastics using a hot-air furnace. It is one of a number of methods in use for evaluating the reaction of plastics to the effects of ignition sources. The method described does not give a direct measure of the combustibility or rate of burning of a material or any…

This part of IEC 61000-4 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, with regard to: a) repetitive damped oscillatory waves occurring mainly in power, control and signal cables installed in high voltage and medium voltage (HV/MV) substations; b) repetitive damped oscillatory waves occurring mainly in power, control…

ISO 5658-2:2006 specifies a method of test for measuring the lateral spread of flame along the surface of a specimen of a product orientated in the vertical position. ISO 5658-2:2006 provides data suitable for comparing the performance of essentially flat materials, composites or assemblies that are used primarily as the exposed surfaces of walls in buildings and transport vehicles, such as ships…

This part of IEC 61000 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, to non-repetitive damped oscillatory transients (ring waves) occurring in low-voltage power, control and signal lines supplied by public and non-public networks. The object of this basic standard is to establish the immunity requirements and a common…

ISO 5350-4:2006 specifies a method using instrumental inspection by reflected light for the estimation of visible dirt and shives in pulp manufactured in sheets, in terms of Equivalent Black Area (EBA) of dirt specks within the physical area range of 0,02 mm2 to 3,0 mm2. Using the algorithm prescribed in ISO 5350-4:2006, the maximum dirt size is limited to 3,0 mm2. Extension to other speck sizes…

ISO 17071:2006 specifies two alternative methods for determining the fogging characteristics of leathers used in the passenger compartments of motor vehicles, namely Method A and Method B. These are two different test procedures to measure the volatile components and there is no mathematical correlation between the results obtained with Method A and those with Method B. Method A determines by…
