Standard for EM Examination of Ferromagnetic Steel Wire Rope
ASTM E1571 - 11 outlines a procedure to standardize an instrument and to use the instrument to examine ferromagnetic wire rope products in which the magnetic flux and magnetic flux leakage methods are used. If properly applied, the magnetic flux method is capable of detecting the presence, location, and magnitude of metal loss from wear, broken wires, and corrosion, and the … [Read more...]
Connectors for Electronic Equipment Standard
IEC 60603-7:2008+A1:2011 covers 8-way unshielded free and fixed connectors and is intended to specify the common dimensions, mechanical, electrical and environmental characteristics and tests for the family of IEC 60603-7-x connectors. These connectors are intermateable and interoperable with other IEC 60603-7 series connectors. This new edition includes the following … [Read more...]
IEC Releases Fixed Capacitors Standard for use in Electronic Equipment
IEC 60384-2:2011 applies to fixed capacitors for direct current, with metallized electrodes and polyethylene-terephthalate dielectric for use in electronic equipment. These capacitors may have "self-healing properties" depending on conditions of use. They are primarily intended for applications where the a.c. component is small with respect to the rated voltage. Two performance … [Read more...]
Radiation Protection Instrumentation Standard
IEC 61577-3:2011 describes the specific requirements for instruments measuring the volumetric activity of airborne short-lived radon decay products and/or their ambient potential alpha-energy concentration outdoors, in dwellings, and in workplaces including underground mines. This standard applies practically to all types of electronic instruments that are based on grab … [Read more...]
New Law Focuses on Rare Metals in Electronics
A provision on "conflict minerals" that was slipped into a 2010 financial reform law, the Dodd-Frank Act, will help educate American consumers on what is in their smart phones, computers and other electronics and where U.S. electronics manufacturers are getting those rare metals. In the jungles and mountains of the Democratic Republic of the Congo, armed groups have been … [Read more...]
IEC President: Group’s Work Cannot Remain Static
In a recent speech to the International Electrotechnical Commission (IEC) Council, IEC President Dr. Klaus Wucherer said that while standards and conformity assessment systems will remain essential for industry, governments and other end-users, the IEC’s involvement cannot remain static. In this increasingly competitive world, the IEC, in addition to providing a high level of … [Read more...]
Portable Very High Frequency Radiotelephone Equipment Standard
This standard states the minimum technical characteristics and methods of measurement required for portable Very High Frequency (VHF) radiotelephones with integrated handheld class D DSC operating in certain frequency bands allocated to the maritime mobile service using either 25 kHz channels or 25 kHz and 12,5 kHz channels.Preview the standard. … [Read more...]
New Wireless Network Standard Fills in the White Space
The wireless spectrum was carved up in the mid-20th century with protection of commercial radio and television signals as its primary concern. One example of this was the practice of leaving “white space” between broadcast channels to prevent interference by analog signals crowded too close together. Especially since the dawn of the digital age, technology has gotten better and … [Read more...]
Semiconductor Magnetic and Capacitive Coupler Standard
IEC/PAS 60747-17:2011(E) gives the terminology, essential ratings, characteristics, safety test and the measuring methods of magnetic and capacitive couplers. It specifies the principles of magnetic and capacitive coupling across an isolation barrier and the related requirements for basic isolation and reinforced insulation.Preview the standard. … [Read more...]
