RoHS: 2003 No. 2002/95/EC of the European Union adopted in electronic and electrical equipment on the restriction of use of hazardous substances "instruction, usually referred to as the Restriction of Hazardous Substances Directive or RoHS. In all Member States of the European Union since January 2006 as law enforcement. This instruction strictly limits the use of six hazardous substances in electrical and electronic equipment. And it has close contact No. 2002/96/EC electronic equipment, garbage "(WEEE) directive. This directive provides for the collection of electronic products, recycling and reuse of the detailed requirements of the legislative bodies to solve a large number of poisoning caused by e-waste initiative.

ATEX: since July 2006, in the EU region organizations must comply with the directive of the European Union, as far as possible to protect employees from explosive air environment **** dangerous.

ATEX Directive is divided into the following two (one for manufacturers, a user equipment):

• ATEX 95 Equipment Directive No. 94/9/EC, Equipment and protective systems used in potentially explosive atmospheres environment.

• ATEX 137 work environments Directive No. 99/92/EC, raise the minimum requirements of the work in the potentially explosive atmospheres environment, **** dangerous safety and health protection of workers may face.

ATEX from 94/9/EC directive French prefix: Appareils destinés à être utilisés en ATmosphères Explosibles.

MIL:
The U.S. Defense Department include the following sections: Army, Navy, Air Force and DLA (Defense Logistics Agency). DLA's role is to provide logistical support to other departments. DLA by four DSC (Defense Supply Center), one of Colombus, Ohio known as the DSCC. It is responsible for standardization and procurement of components for military and other related units (including the Army, Navy, Air Force, NASA, NATO, and the U.S. Federal Aviation Administration, etc.). Currently, DSCC manages a total of more than two million components and suppliers.

DSCC audit and publish the QML (qualified manufacturers directory) protocol and QPL (Qualified Products List) protocol of the manufacturer. The DSCC also responsible MIL document management system.

The MIL document suitable for many applications:

EEE components (APEM products belonging to this field)

Radar equipment

Radio navigation equipment

Night vision equipment

......

Several different document types:

Military Handbook (MIL-HDBK): includes only recommendations did not ask.

: Testing, technology and processes to the specific requirements of military standards (MIL-STD).

Military specifications (MIL-PRF or MIL-M-xxx, MIL-C-xxx, etc.): General documentation. Requirements and test procedures for each type of component.

Specifications (MIL-DTL or MIL-PRF): similar to the manufacturer's specifications. This document gives the specific requirements of a product, its universal military standard reference number.

QPL (Qualified Products List): Part Number DSCC certified by the directory.
