Statistical interpretation of data tests and confidence intervals relating to proportions (ISO 11453:1996, IDT)
MS ISO 11453:2002 (CONFIRMED:2023)
Status : 2nd Confirmation
Format : PDF

This Malaysian Standard describes specific statistical methods for addressing the following questions. 
a) Given a population of items from which a sample of n items has been drawn, x of the s ....Read more ample items are found to show a specified characteristic. What proportion of the population has that characteristic? (See A forms, subclause 8.1.)
b) Is the proportion estimated in a) different from a nominal (specified) value? (See B forms, subclause 8.2.)
c) Given two distinct populations, are the proportions with the characteristic in the two populations different? (See C forms, subclause 8.3.)
d) In b) and c) how many items must be sampled in the population(s) to be sufficiently sure that the result of the test is correct? (See 7.2.3 and 7.3.3.)

It is essential that the drawing of samples does not have any appreciable effect on the population. If the sample drawn at random is less than 10 % of the population this is usually satisfactory, but if the sample is greater than this, reliable re Close

To perform this test, the devices under test (DUT) is exposed to a magnetic disturbance field. 
The radiating loop method can be applied to small DUTs or to larger DUTs by positioning the coil in multiple locations. The Helmholtz coil is sometimes used as an alternative method. This technique is limited by the relationship between the size of the DUT and the size of the coils. The electromagnetic disturbances considered in this part of ISO 11452 are limited to continuous narrowband electromagnetic fields. Immunity measurements of complete vehicles can generally only be carried out by the vehicle manufacturer for reas Close
