Plastics are often used out- or indoors exposed to daylight or to daylight behind glass for long periods. The effects of daylight, heat, moisture and other climatic stresses may have influence on the aesthetic and mechanical properties of plastics and for that reason the resistance to these effects is investigated.
The EN 54-4 power supply equipment may have its own cabinet, or may be housed with other equipment of the fire detection and fire alarm system, such as the control and indicating equipment of EN 54-2 of EN 54-16. A fire detection and fire alarm system may use more than one power supply equipment.
Within the Kiwa organisation there are a large number of accredited laboratories. This means that the scope of possible tests within the entire Kiwa Group is so wide that is impossible to mention them all here. Although not limited to polymer test...
Heat pumps provide an environmentally friendly way to both heat and cool buildings and to take care of hot water supplies. An increasing number of new products are emerging in the marketplace, all of which must comply with European directives.
