The American Society of Mechanical Engineers (ASME) has published since 1921 a safety code for elevators, escalators,and related equipment. The following is a brie fhistory of how the various editions of this Code addressed the matter of retroactive requirements for existing installations. The 1921 edition did not differentiate between new and existing installations.

This part of IEC 63202 describes procedures for measuring the light-induced degradation (LID) of crystalline silicon photovoltaic (PV) cells in simulated sunlight. The magnitude of LID in a crystalline silicon PV cell is determined by comparing maximum output power at Standard Test Conditions (STC) before, and after, exposure to simulated sunlight at a specified temperature
