NEMA 4 cabinet questions
Some questions about using a NEMA 4 cabinet: (1) Is the environment inside the cabinet considered pollution degree 1, no matter what the external environment is? (2) We need to install a water drain at the bottom of the cabinet. Can we use a positive-acting valve without violating the cabinet's NEMA 4 rating? (3) The cabinet doors will need to be opened periodically for maintenance. How does this affect the pollution degree inside the cabinet? By the way, these questions are in the context of certifying the product under the CB 950 scheme.

Electrical Equipment Using Liquid Lithium Chloride
Dear All, I am working on a dehumidifier used as an accessory for a central air conditioning system used on the rooftop. It employs an electrical control box, compressor, fan unit and large amounts of Lithium Chloride which is usually handled by service personnel. 1. What is the level of lithium chloride which can be emitted to the air in North America? What about Europe? 2. Are there any special precautions which must be taken when designing the equipment in regards to protection against human touch and/or inhalation of this liquid compound? 3. The UL1995 Standard for Heating and Cooling Equipment covering the product does not contain the additional requirements needed for chemical hazards? How are chemical hazards treated when evaluating any equipment for UL and any other NRTL. How about Europe? Thanks in Advance, PETER S. MERGUERIAN MANAGING DIRECTOR PRODUCT TESTING DIVISION I.T.L.

Horn antennas, pre-amplifier, and return loss measurement
Hi, Folks, Is there anyone can direct me to some sources of horn antennas preamplifiers. What I need are sets of horn antenna for spurious emissions testing to meet FCC Part 101. 1 to 18GHz, 18 to 26.5GHz, 26.5 to 40GHz, or 18 to 40GHz instead, 40 to 60GHz, 50 to 75GHz, or 40 to 75GHz instead, 75 to 110GHz, 110 to 170GHz, or 75 to 170GHz instead. Due to the significant space loss over 110GHz, I guess I also need a set of preamplifier from 110 to 170GHz. I am also studying on return loss measurement methodologies to meet ETSI requirement for radios RF port. Since NAMAS calibration of network analyzer may cost thousands bucks, I am wondering if I could achieve a good result (in terms of accuracy and uncertainty) using spectrum analyser and waveguide coupler. If anyone by any chance has an ready error model of the test setup using spectrum analyzer and waveguide coupler, I appreciate you could share with me to short my research path. Thanks in advance.

Digital logic and EMI
I have a subject the someone may be able to help with. I am wondering if any of the member have come across any helpful material evaluating various manufacturer's digital logic families as they relate to EMI issues? I know this is a very broad subject and many issue such as; speed, power consumption and drive capability all have an impact and must be consider in the same context. Am I dreaming in Technicolor?

RE: China Standard for ITE product
Hello George, To speed up CCIB certification under the Import/Export Commodity Inspection Law Safety License System it is recommended to have the line cord plug CCEE certified. However, it is not mandatory. To the best of my knowledge there is no line cord standard for China (PRC), only component standards for the plug, cordage, and connector.

The only delta I know of is that tests are to +/-10% rated voltage versus the norm of +6%/-10%. A CB Certificate/Test Report, though not required, is advised for time and cost purposes. The line cord must have CCEE approval and have the Great Wall mark. As of 1/1/00 all listed ITE must also meet EMC EMI requirements based on CISPR 22. This includes previously safety approved products. In summary, the requirements are not that much different from the global 230V community, although the process itself is the most complex I have encountered with many agencies/offices involved (SAIQ, CQC, CCIB, Review Offices, Testing Labs).
