When the toggle switch leaves the factory, it needs to go through various standards of identification, so we should pay attention to these problems and do a good job in the basic requirements of the switch.
ANSI: abbreviation of American National Standard Institute; it is a national standard setting organization in the United States, responsible for the design and performance approval of electronic / electrical components sold all over the world. Official website: www.ansi.org.
CSA: Canadian Standards Association.
IEC: International Electrotechnical Commission.
IECQ: the quality assessment system for electronic components launched by IEC in 1983 in order to promote cross regional transactions of qualified electronic components around the world. Based on this globally recognized certification system, any electronic component provided by a qualified s manufacturer and distributor can be used directly and safely without further testing.
NEMA: association of electrical manufacturers, an American standard setting organization. Mainly for the switch products installed on various equipment casings, which need to have a certain level of protection function against the invasion of liquid, solid, dust and corrosive elements. NEMA ratings are primarily used for industrial and outdoor applications. See IP.
Semko: Svenska elektrika Materielkontrollanstalten of Sweden, the first-class European certification body in Sweden.
Sev: schweizerischer elektrotechnisher Verein of Switzerland, a testing agency in Switzerland.
UL: Underwriters Laboratories Inc., Inc.
VDE: Verband Deutsche elektrotechniker of Germany, German Institute of electrical engineers.
RoHS: Directive 2002 / 95 / EC "on the restriction of the use of hazardous substances in electronic and electrical equipment" adopted by the European Union in February 2003, generally referred to as the hazardous substances restriction directive or RoHS. It has been enforced as a law in all EU Member States since January 2006. This directive strictly limits the use of six harmful substances in electronic and electrical equipment. Closely related to it is the WEEE Directive No. 2002 / 96 / EC. This directive specifies the detailed requirements for the collection, recycling and reuse of electronic products, and is an initiative of the legislature to solve a large number of poisoning incidents caused by electronic waste.
ATEX: since July 2006, any organization in the European Union region must comply with this directive of the European Union, and try to protect employees working in explosive atmosphere from explosion risks.
The ATEX directive is divided into the following two (one for the manufacturer and one for the user of the device):
ATEX 95 Equipment Directive, No. 94 / 9 / EC, applies to equipment and protection systems in potentially explosive atmospheres.
ATEX 137 work environment directive, No. 99 / 92 / EC, raises the minimum requirements for the safety and health protection of workers who may be exposed to explosion hazards while working in potentially explosive atmospheres.
ATEX comes from the French prefix of Directive 94 / 9 / EC: Appareils destination é s à tre utilis é s en atmosph è res explosibles.
MIL:
The U.S. Department of defense includes the following components: Army, Navy, air force, and DLA. DLA's role is to provide logistical support to other departments. DLA consists of four DSC (Defense Supply Center), one of which is located in Columbus, Ohio and is called DSCC. It is specifically responsible for the standardization and procurement of components for the military and other associated units (including the army, Navy, air force, NASA, NATO, FAA, etc.). At present, DSCC manages more than 2 million components and suppliers in total.
DSCC can audit the manufacturer and issue the QML (qualified manufacturer catalog) agreement and QPL (qualified product catalog) agreement. DSCC is also responsible for the management of mil system documents.
Mil documents are suitable for many applications:
EEE components (APEM products belong to this field)
Radar equipment
Radio navigation equipment
Night vision equipment
Several different document types:
Military manual (Mil-HDBK): only suggestions, no requirements.
Military standard (MIL-STD): specific requirements for testing, process and processes.
Military specifications (mil-prf or mil-m-xxx, mil-c-xxx, etc.): general documents. It is mainly about the requirements and test flow of each type of components.
Specific specifications (mil-dtl or mil-prf): specifications of similar manufacturers. This document gives the specific requirements for a product and the reference number of the general military industry standard.
QPL (qualified product catalog): the catalog of all product item numbers certified by DSCC.
The factory verification of the toggle switch requires these standards, so the toggle switches we produce all meet the national standards, please have a detailed understanding.
