Green initiatives issued by Verizon will come into effect this summer - MET can help
|
 |
In June, 2010, Verizon's Technical Purchasing Requirement VZ.TPR.9307 will require qualifying printed board assemblies manufactured with lead-free solder. |
Contact MET to start testing to VZ.TPR.9307 today, be ready for Verizon this June.
As a reminder, MET is Verizon certified for TEEER testing to VZ-TPR.9205.
Equipment purchased and installed prior to the effective date of this initiative, can be reviewed and tested by MET to confirm its compliance to TEEER requirements.
Additionally, MET tests to AT&T-TP-762000 Network Equipment Power, Grounding, Environmental and Physical Design Requirements.

MET upgrades photometric capabilites
MET's spectroradiometric measurement system can measure over all or part of the entire 200 nm to 30 µm wavelength range, and will support weathering testing prescribed in ASTM G155, SAE 1885(J2412), Method 505.4 of MIL-STD 810, and solar panel testing to UL1703. Solar radiation is a key component in most life cyling test suites. |

MET Laboratories performs Radiated Emissions Testing new requirements of EN55022:2006+A1:2007).
Previous versions of EN55022 did not require radiated emission testing above 1GHz. This new version of EN55022 specifies REE testing up to 6 GHz. Test methodology is also significantly different from FCC/ANSI C63.4 requirements. The standard specifies that the testing is performed using a test site with reflection free conditions (i.e. free space method). A regular semi-anechoic chamber does not provide a reflection free environment In order to achieve free space conditions in a semi-anechoic chamber it becomes necessary to place absorbing material on the chamber floor between the EUT and the measuring antenna.

Ask an Expert
Q: What is AT&T's position on acoustical noise requirement.
A: Setting limits on acoustical noise, in addition to being a requirement of GR-63-CORE, is also an OSHA requirement for the protection of personnel. AT&T has made it clear that it will not accept products that do not meet acoustical noise requirements and fan filter requirements.
Q: Are there routing methods for cabling that would help reduce EMI emisssions?
A: Use wiring harnesses and wire ties when routing cables inside a box. EMI pickup on I/O cables is a major contributor to overall radiated noise. Route cables along the sides of the box and away from high frequency components and switching power supplies.

Important Reminder: New Mandatory Labeling Requirements for Product Safety Compliance in Canada Effective April 1, 2010
Effective April 1, 2010 the Standards Council of Canada will require all new certification marks to clearly identify all standards used or be accompanied by the term “Electrical Safety” or other appropriately descriptive term.
If the current MET Mark being used does not meet this requirements, clients are required to submit a revised drawing for approval along with PAR (Project Amendment Request) form available at http://www.metlabs.com/safety/info/Par.pdf. If the revised MET Mark has not been approved by April 1, 2010, then certification will be terminated. Please contact MET if you have any questions.
