FCC to Review Mobile-Phone Radiation Safety
The U.S. Federal Communications Commission plans to ask whether its standards protect people from mobile-phone radiation, a question it hasn’t posed in 15 years, as people use smartphones for longer, more frequent calls. A formal enquiry would review the FCC’s standards with the concerns of more frequent use, longer-use, new mobile-phone technology, and use by children in … [Read more...]
Microwave Therapy Equipment Safety Standard
IEC 60601-2-6:2012 specifies the minimum requirements considered to provide for a practical degree of safety in the operation of microwave therapy equipment. This particular standard amends and supplements IEC 60601-1 (third edition, 2005 and amendment 1, 2012). This second edition cancels and replaces the first edition of IEC 60601-2-6, published in 1984. This edition … [Read more...]
HEMP Immunity Test Methods for Equipment and Systems
IEC 61000-4-25:2001+A1:2012 describe immunity test levels and related test methods for electrical and electronic equipment and systems exposed to high-altitude electromagnetic pulse (HEMP) environments. 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...]
Determining Space for Capacitors and Resistors with Unidirectional Terminations
IEC 60717:2012 applies to capacitors and resistors with unidirectional wire terminations intended for use in electronic equipment. This standard provides a method for determination of the space required by capacitors and resistors with unidirectional wire terminations. NOTE: Instead of measuring the actual space, it may be sufficient to ensure that a component fits into the … [Read more...]

IEC 61000-4-25:2001+A1:2012 describe immunity test levels and related test methods for electrical and electronic equipment and systems exposed to high-altitude electromagnetic pulse (HEMP) environments. 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...]
