Introduction A spectroradiometer is an instrument ( a light measuring tool ) used to measure the wavelength and amplitude of the light emitted from the light source. Spectrometers are used to discriminate the wavelength based on the position at which the light hits the detector array, allowing the full spectrum to obtain a single acquisition. A colorimeter is defined as ”an instrument that i...
What is the needle flame test The full name of IEC 60695-2-2 is Fire hazard testing Part 2: Test methods – Section 2 Needle flame test. Needle flame test was prepared by IEC technical committee 89: Fire hazard testing. The following is the related introduction of IEC 60695-2-2 Scope. This section of IEC 60695-2-2 specifies a needle flame test to simulate effect of small flames which may result...
What is RoHS? RoHS is a legal requirement set forth by the EU legislation. The full form of RoHS is Restriction of Hazardous Substances. This standard has been in effect since July 1, 2006. It is mainly used to control the materials and manufacturing processes of electrical and electronic equipment. It also helps in improving human health and environmental protection. The goal of this standard is ...
Goniophotometer A goniophotometer is a measuring device. It is used to measure directional light distribution characteristics in lamps and luminaires. It collects photometric data from different spherical locations. Then it creates a web of photometric data that encircles the item under test. Gonio photometric data is obtained using a variety of instruments and is delivered in a variety of angular...
What is the glow wire test? The Glow wire tester ZRS-3H/ZRS-3HS is suitable for providing resistance to abnormal heat and fire tests on the lighting lamps, the electronic products and household appliances. It uses a high-temperature coating spraying on the steel structure and all the imported instruments display with the easy operation and the stable performance. This equipment is applicable to t...
Security is critical in the home appliance business. The purpose of fire safety rules is to assess and rate the flammability of materials used in appliance wiring systems. This is owing to the possibility of human error, over-current, or short circuit failures in a wiring system for an appliance. One such rule that is now in use in the appliance industry is the glow wire test. This regulation is m...
The use of LEDs has increased with the advancement of technology. So, in order to meet today’s needs LEDs must be thoroughly evaluated. This is done using standardized and uniform LED testing methodologies. The LM-79 testing standard was developed by the Illuminating Engineering Society of North America, commonly known as IESNA. It was to offer more trustworthy results when evaluating such t...
