9.1 General 9.1.1 A device shall have live parts protected against exposure to contact by persons when fully assembled using all essential parts (described in 9.1.5) and installed in the intended manner. Exception No. 1: Male blades which are energized only when mated with the corresponding outlet are not required to comply with this requirement. Exception No. 2: Exposed wiring terminals or other ...
Colorimeter is also called portable colorimeter, color analyzer and color colorimeter. The colorimeter is a simple color deviation testing instrument, that is, to make a filter that simulates the spectral characteristics equivalent to the color sensitivity of the human eye, and use it to measure the light of the sample plate. The key is to design the spectral sensitivity characteristics of this ph...
Isolation transformer is a special type of transformer, which has its input and output winding connected in an electrically isolated fashion, mainly used in occasions with reverse phase separation, to realize electrical isolation and simultaneous voltage step-up/down. The main application of isolation transformer is to electrically isolate two related circuits, usually applied in electronic indust...

SMT DT1_AL The object of ...
When it comes to the performance and reliability of components and systems, the aerospace sector is among the most demanding and crucial. Aerospace equipment must undergo thorough testing at every stage of the design and production process to guarantee its reliability and usefulness. In order to simulate the wide range of environmental conditions that aerospace components and systems may face over...
Introduction: A rising problem, light pollution has an impact on both urban and nature settings. It describes the brightening of the night sky and the disturbance of natural light cycles caused by artificial lighting that is either too bright or pointed in the wrong direction. Goniophotometric measurement is essential for measuring and studying light pollution because of its capacity to evaluate t...
16 Accessibility of Live Parts 16.1 General 16.1.1 A live part that poses a risk of electric shock shall be located or enclosed so that the risk of contact is reduced. 16.1.2 The input impedance of the voltmeter used to measure voltage in accordance with the requirements of 16.2.1 and 16.3.1 is to be a minimum of one megohm. The input impedance of a meter with more than one megohm input impedance ...
Introduction: Solar panels are essential for capturing solar energy, which has quickly become an important renewable energy source. The need of rigorously testing the performance of solar panels in a variety of climatic situations has increased in light of the rising demand for efficient and long-lasting solar panels. In this respect, thermal chambers become useful. The efficiency and longevity of...
