HONDA QUALITY STANDARDS - SCOPE AND PURPOSE

Scope; this standard defines, describes and specifies the point of delivery to the network user, the main features of the voltage supplied by a global network of low voltage distribution and medium voltage under normal operating conditions. This standard describes the limits or values ​​to be expected to remain the constant voltage across the general distribution network and does not describe the typical situation is usually an individual user on the network.This European Standard does not apply to abnormal operating situations, including the following:- Temporary conditions designed to maintain power supply to network users after a failure or during maintenance work or construction on the network, or to limit the extent and duration of a power interruption;- In case of non-compliance...

ACCURACY ,REPEATABILITY AND REPRODUCIBILITY

AccuracyThe accuracy of a test method is the proximity of different experimental results obtained in samples the same. The calculation of accuracy is given by the repeatability r and reproducibility R, both defined in ISO 5725-1. The calculation methods are given in ISO 5725-2, ISO 5725-3 and ISO 5725-4.R r values of dissipation factor of an insulating liquid depend on the nature of the liquid tested, whether the fluid is new or used and the temperature, these values are altered and is very low (Less than 10-4), as is the case in highly insulating liquids, which are altered significantly by the impurities, handling, cleaning the test cell, and so on.Repeatability (r)If obtained in a laboratory two measures A and B, at room temperature, can...
