IEC 60747-5-14:2022(E) specifies the measuring method of the surface temperature of single LED die or package, based on the thermoreflectance (TR) method. TR is the effect that the reflectance of light changes with the temperature of a substance. This part measures relative change in the reflectance of light from a metal film deposited nearby on the metallurgical pn junction as the relative change in the LED junction temperature. The surface temperature can be approximated as the junction temperature when the thermal resistance effect between the metal surface and the pn junction is negligibly small.

IEC 60747-5-13:2021 provides the accelerated test method to assess effects of the tarnishing of silver and silver alloys used for LED packages due to hydrogen sulphide. Particularly, this test method is intended to give information on silver and silver alloy tarnishing effects to the luminous/radiant flux maintenance of LED packages. Additionally, this test method can give information on electric performances of LED packages due to corrosion of silver and silver alloys.
The object of this test is to determine the influence of atmospheres containing hydrogen sulphide on parts of LED packages made of: silver or silver alloy; silver or silver alloy protected with another layer; other metals covered with silver or silver alloy.
Testing other degradations that are susceptible to affect luminous/radiant flux maintenance and/or electric performance (e.g. degradation of copper or silicone parts) is not the object of this test. This test might not be suitable as a general corrosion test, i.e. it might not predict the behaviour of flux and/or electric characteristics and connections in industrial atmospheres. This document is applicable to LED packages for lighting applications only if referenced by an IEC SC 34A document.

IEC 60747-5-10:2019(E) specifies the measuring method of the internal quantum efficiency (IQE) of single light emitting diode (LED) chips or packages without phosphor. White LEDs for lighting applications are out of the scope of this document. This document utilizes only the relative external quantum efficiency (EQE) measured at an operating room temperature. In order to identify the reference IQE, an operating current corresponding to the injection efficiency of 100 % is found and the radiative efficiency is determined by the infinitesimal change of the relative EQE at that point. The IQE as a function of current is then calculated from the relative ratio of the EQEs to the value at the reference point, which is called room-temperature reference-point method (RTRM).

IEC 60747-14-4:2011 applies to semiconductor accelerometers for all types of products. This standard applies not only to typical semiconductor accelerometers with built-in electric circuits, but also to semiconductor accelerometers accompanied by external circuits. This standard does not (or should not) violate (or interfere with) the agreement between customers and suppliers in terms of a new model or parameters for business.
NOTE 1: This standard, although directed toward semiconductor accelerometers, may be applied in whole or in part to any mass produced type of accelerometer.
NOTE 2: The purpose of this standard is to allow for a systematic description, which covers the subjects initiated by the advent of semiconductor accelerometers. The tasks imposed on the semiconductor accelerometers are not only common to all accelerometers but also inherent to them and not yet totally solved. The descriptions are based on latest research results. One typical example is the multi-axis accelerometer. This standard states the method of measuring acceleration as a vector quantity using multi-axis accelerometers.
NOTE 3: This standard does not conflict in any way with any existing parts of either ISO 16063 or ISO 5347. This standard intends to provide the concepts and the procedures of calibration of the semiconductor multi-axis accelerometers which are used not only for the measurement of acceleration but also for the control of motion in the wide frequencies ranging from DC.
