GR-63-CORE, Flame Spread Clarification

 

For flame tests involving vertically oriented circuit boards, the methane line burner shall remain lit for a minimum of 180 seconds from the start of the test. At 180 seconds, the methane flow is approximately ½ the maximum flow rate of the profile. If the methane burner does not remain lit during this time period, stop the test and restart the test from the beginning with the fans powered off for the duration of the test.  

Flame tests involving horizontally oriented circuit boards shall be performed per the GR procedure. If the methane line burner will not remain lit at the 5 lpm flow rate, restart the test from the beginning with the fans powered off for the duration of the test.

GR-1089 – ESD Warning Labels

 

Electronic components are susceptible, and therefore sensitive, to ESD effects. Regardless of immunity performance during testing, products shall have ESD warning labels permanently affixed to the front of the chassis, in a visible area on the assembly.  If cards can be inserted into both the front and rear of the chassis, ESD warning labels shall be placed on both the front and the rear of the chassis assembly.  The faceplate of individual circuit cards/modules need not be labeled.

ATCA Standards:

Verizon takes exception to the slot-powering scheme defined by the Advanced Telecom Computing Architecture (ATCA) standards. The power allocated to each slot - 200 Watts per slot or up to 3200 Watts per shelf - is excessive and leads to high failure rates during NEBS testing. Conformance to NEBS requirements is a gating criterion for product approval. We evaluate each product on its merit and select the most cost effective solution to satisfy Verizon's business needs. NEBS compliance testing remains the only set of requirements that Verizon uses to evaluate products for safety, interference and functionality before deployment. For more information about Verizon's NEBS requirements, please download a copy of the TCG NEBS Compliance Checklist from this webpage.
