IEC 60068-2-82:2007 specifies whisker tests for electric or electronic components representing the finished stage, with tin or tin-alloy finish. However, the standard does not specify tests for whiskers that may grow as a result of external mechanical stress.
This test method is employed by a relevant specification (international component or application specification) with transfer of the test…

IEC 61937-2:2007 specifies the digital audio interface to convey non-linear PCM encoded audio bitstreams applying IEC 60958-1 and IEC 60958-3. This standard specifies burst-info which defines content information about the data contained in the burst payload. This second edition cancels and replaces the first edition published in 2000. This edition contains the following significant technical…

Cylindrical cork stoppers — Physical tests — Part 7: Determination of dust content
ISO 9727-7:2007 specifies a test method for determining the dust content of a cylindrical cork stopper.
It is applicable to all types of cylindrical cork stoppers ready for use, intended to be completely inserted in the bottle neck (straight cork stoppers).
Soil quality — Determination of effective cation exchange capacity (CEC) and exchangeable cations us...
ISO 23470:2007 specifies a method for the determination of the cation exchange capacity (CEC) and the content of exchangeable cations (Al3+, Ca2+, Fe2+, K+, Mg2+, Mn2+, Na+) in soils using a hexamminecobalt trichloride solution as extractant.
ISO 23470:2007 is applicable to all types of air-dried soil samples which have been prepared in accordance with ISO 11464.
