ACB, in cooperation with Interference Technology, announces a new on-line Engineering Video series, This new series provides education and explanation of fundamental and fine engineering topics, aimed at the test laboratory and compliance market. Presented in short, focused segments, EspressoEngineering examines current events and engineering topics in our community in about the time it takes for a cup of coffee [more or less.]. Visit

Second International Workshop On Mutual Recognition Agreements For Conformity Assessment Of EMC And Telecommunications Regulations

On May 5-7, 2009, the National Institute of Standards and Technology (NIST) and the U.S Federal Communications Commission (FCC) will co-host the Second International Workshop on Mutual Recognition Agreements for Conformity Assessment of EMC and Telecommunications Regulations at NIST in Gaithersburg, Maryland. Click Here for more information.

This is a can’t-miss opportunity for Test Labs, Certification Bodies and parties involved in International Product Approval activities.

Questions and Answers:

QUESTION: We have a tire pressure monitor operating at 433MHz. The receiver is powered from 12VDC (DC to DC). What standard must we follow? FCC part 15 B or SAE? If Part 15B is power line conducted emissions testing required?

ANSWER: The intentional radiator portion of this device must comply 15C. This device, specifically, must comply with 15.231. For all receivers associated with this device, only 15B will apply for unintentional emitters. No power line conducted emissions are required for battery-operated equipment.

If this device is a “super-regenerative receiver”, it must be ‘keyed” with a radiated signal at its receive frequency to maximize emissions. Please see ANSI C63.4 for further details.

(“SAE” is the Society of Automotive Engineers, a standards-making body in the United States. The regulatory requirements for this type of device fall under the FCC. The SAE does not regulate RF transmitters per se. It may have other requirements, however, that are industry-specific and are generally called out by the specific automobile manufacturer.)

QUESTION: Was EN50361 replaced by EN62209-1 recently? If so how about EN50360?

ANSWER: Presently, there is a SAR standard for mobile phones, it is EN 50360. (Also, EN 50361).
EN 50360 is the harmonised standard for performing the tests on phones.

However, there are no harmonised standards for SAR on any other device: WLAN dongle, WiMAX dongle, Walkie-talkie, etc. At this time, manufacturers of these devices need to decide on a set of tests to which to claim compliance. They may also request a Notified Body to advise on a test suite to use and possibly give an opinion on the TCF.

There are new standards under development: EN 62209-1 and EN 62209-2. These are generic SAR standards for Head devices and Body devices. They are intended to cover SAR tests on many types of devices.
When published and harmonized, it is expected that they may replace EN 50360.

EN 62209 is not yet harmonized. This means that the manufacture should continue following any existing harmonized standard.

If they decide to use EN 62209, then they should obtain a Notified Body opinion.

QUESTION: I understand that TCBs CANNOT review Part 90 subpart Z in the 3650 – 3700MHz band (it may be the application for 3.5G WiMAX in FCC). Is it correct? Or is Certification under “Permit But Ask” the necessary route for approval?

ANSWER: Part 90 applies and, because this device operates on contention based protocol, it must be Certified by the FCC.

QUESTION: Please help to clarify the “Canadian Representative” requirements.
1. Does IC require a physical Canadian to answer the phone from IC?
2. Can the Canadian rep be located in the U.S or Japan to answer the phone which has been transferred from his office in Canada?

ANSWER: A company located outside Canada who applies for certification must provide a Canadian representative with a Canadian address and a Canadian telephone number. The Canadian representative must be able to answer telephone calls from Industry Canada during normal business hours within the Canadian time zones. The Canadian Representative is also responsible to provide on request, audit samples free of charges to Industry Canada (no shipping charges or custom duty charges) and Industry Canada must be able to ship back the audit samples free of charges to a Canadian address.

Therefore, to answer your question, if the person or company acting as the Canadian representative is providing a Canadian address and telephone number and can meet all conditions listed above but is, in reality, located outside Canada, this would still satisfy our requirements and would be acceptable to Industry Canada.
