Specifications for test equipment and instrumentation test set-up, test procedures, pass/fail criteria, and test documentation requirements are also defined by this standard. … [Read more...]
Surface Acoustic Wave (SAW) Filters Standard
IEC 60862-2:2012 gives practical guidance on the use of SAW filters which are used in telecommunications, measuring equipment, radar systems and consumer products. IEC 60862-1 should be referred to for general information, standard values and test conditions. This part of IEC 60862 includes various kinds of filter configuration, of which the operating frequency range is from … [Read more...]
Printed Board Assembly Products Standard
IEC 61182-2-2:2012 provides the information on the manufacturing requirements used for fabricating printed boards. This standard determines the XML schema details, defined in the generic standard IEC 61182-2 and some of the sectional standards that are required to accomplish the focused tasks. When other standards are invoked, their requirements become a mandatory part of the … [Read more...]
Safety Requirements Standard for Electrical Equipment for Measurement
IEC 61010-2-033:2012 specifies safety requirements for METERS. The METERS that have a primary purpose of measuring voltage on a live MAINS CIRCUIT are within the scope of this standard. They have various names, but all of them have capability for measurements of voltages on a live MAINS CIRCUIT. Some of the names given to this equipment are as follows: - MULTIMETER; - digital … [Read more...]
Surface Mounted Piezoelectric Devices Standard
IEC 61837-1:2012 deals with standard outlines and terminal lead connections as they apply to SMDs for frequency control and selection in plastic moulded enclosures and is based on IEC 61240. Preview the standard. … [Read more...]
Safer Cadmium Replacement for Military-Aerospace Connectors
Pressure is mounting to meet the tightening requirements of the European RoHS directives, which are pushing towards elimination of cadmium altogether. Cadmium is particularly dangerous when airborne in dust form. It can cause lung disease, kidney failure, and even death. To replace the cadmium content while maintaining conductivity and corrosion resistant properties, Corsair … [Read more...]
SHIELD Act Would Protect Electronic Infrastructure from EMP
Secure High-voltage Infrastructure for Electricity from Lethal Damage Act or SHIELD Act - Amends the Federal Power Act to authorize the Federal Energy Regulatory Commission (FERC), with or without notice, hearing, or report, to order emergency measures to protect the reliability of either the bulk-power system or the defense critical electric infrastructure whenever the … [Read more...]
IEC Publishes Optical Amplifiers Standard
IEC 61291-1:2012 applies to all commercially available optical amplifiers (OAs) and optically amplified assemblies. It applies to OAs using optically pumped fibers (OFAs based either on rare-earth doped fibers or on the Raman effect), semiconductors (SOAs), and waveguides (POWAs). This third edition cancels and replaces the second edition published in 2006. It is a technical … [Read more...]
