7. Tests for verifying the parameters of light sources
And many other tests according to the customer's specification that may be carried out thanks to very good equipment of EZU and also qualified, well-trained personnel and technical facilities. Many of tests may be carried out directly at customer's premises, by our engineers utilizing customer's equipment, and if it is feasible from the technical viewpoint, measuring equipment can be delivered to the place of destination.
We can also offer you the utilization of EZU ´s measuring equipment including our staff to carry out tests in the presence of customer's representatives. If required, the measurement may be carried out directly by the customer using EZU ´s equipment.
Following the successful test results, we can carry out the product certification over a large scale of possibilities in accordance with the purpose of application.
