Technical requirements for electrical devices that earlier have been based on each nations requirements, are today more based on international agreements for more countries.
All international norms concerning electrical devices are the responsibility of the International Electro-technical Commission (IEC), which is a Division of the International Standard Organization (ISO).
The norms from this Division are harmonized at two different continent levels, CENELEC for Europe and NEC for USA.
Most of the countries have their testing authority, following the national norms and regulations. We can name for instance NEMKO for Norway, PTB for Germany, CSA in Canada etc. as well as some other, more marine oriented as DNV for Norway, RINA for Italy, BUREAU VERITAS for France or USCG for USA. All these authorities try to achieve the same goal, to ensure safe installation and operation of electrical equipment.
As consumers in the EU-market, we meet the CE-mark on all types of products. The CE-mark means that the product meets all relevant norms and the manufacturer is responsible for creating a Declaration of Conformity to assure that the product is designed and produced according to the norms.
Many of the Glamox group products are certified by a 3rd. party, which means that also an independent test approval board has tested the product towards appropriate product norms and created the certificate.
EMC is short for Electro Magnetic Compatibility. By this we mean the product capability to function in its environment without disturbing or be disturbed by electromagnetic interference.
The EU Directive refers to European norms for electrical disturbances from a product (EN 50081) and the product immunity towards electrical disturbances (EN 50082).
Glamox has, since the EMC Directive was implemented, built advanced laboratories where we can do all relevant tests. In parallel we have educated our staff to have knowledge on this matter.
An important criteria when designing luminaires is the temperature on all critical components in and outside the product.
The Glamox group has standardized laboratories for all types of heat measurements relevant to luminaires.
Electronics has more and more market share and the heat measurements become more and more important. A rule of thumb says that ten degree decrease in temperature on the electronic will double its lifetime. That is why we always try to find the optimal and coldest position of the electronic components in the fixture.
Ta means “Temperature ambient”. If the fixture is labelled Ta40, it means that it is designed for use in temperature up to 40°C.
IP (Ingress Protection) classification tells us the product capability to avoid ingress from water or solid objects.
The first number refers to solid objects/ dust and the second to water. Glamox group has laboratories for testing IP classification.
Mainly, higher IP-rating means higher dust and watertightness. Please remember the IP66 -rating which also takes in consideration the protection against heavy seas and high pressure water cleaning. IP67- rating does not give any guarantee that IP66 requirements is met. Technical requirements for electrical devices that earlier have been based on each nations requirements, are today more based on international agreements for more countries.
