Here at the "Standard Bearer" we keep a check on ALL Product Compliance related European & international standards activities. The report for this months issue includes activities in EMC, EMF, Electrical Safety, Explosive Atmospheres, Machinery, and RoHS.

(CLICK HERE to go directly to the Standards Update List.)

First the RoHS story.

The Alliance for Telecommunications Industry Solutions (ATIS) released ATIS PP-0600009.2007 - RoHS-Compliant Standard for Structural Metals, Bus Bars and Fasteners.

This standard, developed by the ATIS Network Interface, Power and Protection Committee (NIPP), addresses material and finish specifications that are affected by eco-environmental legislation such as the European Union (EU) Restriction of Hazardous Substances (RoHS) Directive (2002/95/EC).The standard provides the physical technical requirements for telecommunications equipment systems and assemblies intended for installation in network equipment buildings and electronic equipment enclosures. ATIS PP-0600009.2007 also addresses the design and construction of mechanical hardware, cable assemblies and printed wiring boards.

The RoHS requirement to eliminate hexavalent chromium (CrVI) in telecommunications hardware has affected the U.S. telecommunications industry, according to ATIS. CrVI served as a robust materials finish for various metals, particularly aluminum and steel, because it simultaneously meets required criteria for both corrosion protection and electrical conductivity. To successfully replace CrVI, performance requirements for finishes on ferrous materials are written around the performance of trivalent chromium (CrIII) finishes, said ATIS. These are believed to be the only finishes that will meet the performance criteria on ferrous materials.

The RoHS directive affects the manufacturers of electrical equipment. It also has an impact upon those that import these goods into the EU or that rebrand other manufacturers' equipment, said ATIS. (http://www.atis.org/)

Another interesting project, although not strictly a Product Compliance issue, completed by ATIS is the HEMP protection of Telecommunication Links.

ATIS recently announced the release of a standard describing measures that provide a baseline level of protection for the interconnecting links of telecommunications networks against typical geographic and local environmental conditions. The measures are intended to help provide protection from damage caused by specific physical stresses and radiation effects. The standard, Protection of Telecommunications Links from Physical Stress and Radiation Effects and Associated Requirements for DC Power Systems, (ATIS-0600328.2007) was developed by the ATIS Network Interface, Power, and Protection Committee (NIPP)’s Network Electrical Protection subcommittee (NIPP-NEP).

“This document supports the White House National Security Telecommunications Advisory Committee (NSTAC) recommendation that a series of standards be developed by industry experts to consider the effects of HEMP (High-Altitude Electromagnetic Pulse) incidents,” explains Phillip Havens, Member of Technical Staff and Telecom Segment Engineering Manager, Littelfuse and chair of the ATIS NIPP-NEP subcommittee. “The ATIS NIPP-NEP subcommittee has a long, successful history of producing standards that support the NSTAC recommendations. This specific standard defines practices for maintaining the reliability of the telecommunication networks during extreme physical threats.”

The standard addresses protection against such physical threats as: vibration, water penetration, temperature, fire, lightning, wind, ice, construction stresses, corrosion, loss of telecommunications power systems, and radiation effects. The radiation effects encompass electromagnetic interference from transmitting antennas, solar activity, and limited nuclear disaster (e.g., nuclear power plant failure.)

The standard’s protection measures apply to the telecommunications links that interconnect environmentally controlled centers of telecommunications networks including feeder and local distribution plant. The links are optical fiber, metallic-conductor, or coaxial cables of trunk, feeder and local distribution plant. They include connections and repeater points that are on towers, antennas, poles, or in manholes and pedestals, and that are not necessarily environmentally controlled. The terminations of the links in environmentally controlled structures and their power sources are included but the structures themselves and their contents are excluded.

The standard can be purchased in the ATIS document center at: --- https://www.atis.org/docstore/default.aspx

Next, with the publication of BS EN 60079-17:2007, we discuss Electrical installations inspection and maintenance in Explosive atmospheres.

Electrical installations in hazardous areas possess features specially designed to render them suitable for operations in such atmospheres. It is essential for reasons of safety in those areas that, throughout the life of such installations, the integrity of those special features is preserved; they therefore require initial inspection and either:

• Regular periodic inspections or
• Continuous supervision by skilled personnel in accordance with this standard and, when necessary, maintenance.

Correct functional operation of hazardous area installations does not mean, and should not be interpreted as meaning, that the integrity of the special features referred to above is preserved. BS EN 60079:17 applies to users and covers factors directly related to the inspection and maintenance of electrical installations within hazardous areas only, where the hazard may be caused by flammable gases, vapours, mists, dusts, fibres or flyings.

BS EN 60079:17 was published on 31 October 2007 and replaces BS EN 60079-17:2003 and BS EN 61241-17:2005.

IEC Technical Report 62153-4-1 Ed. 1.0 - Metallic communication cable test methods - Part 4-1: Electromagnetic compatibility (EMC) - Introduction to electromagnetic (EMC) screening measurements

Publication date: 2007-11-21

Abstract: Screening is one basic way of achieving electromagnetic compatibility (EMC). However, a confusingly large number of methods and concepts is available to test for the screening quality of cables and related components, and for defining their quality.

IEC/TR 62153-4-1 provides a brief introduction to basic concepts and terms trying to reveal the common features of apparently different test methods. It should assist in correct interpretation of test data, and in the better understanding of screening (or shielding) and related specifications and standards.
