Re: C-Tick mark

Bill, we just received our official copy of the file that describes the C-tick mark. It is strickly a graphics file with no dimensional infomation whatsoever. Very disapointing! Richard Woods Sensormatic Electronics -- From: b...@lyons.demon.co.uk To: ch...@jna.com.au;

Re: C-Tick mark

Cortland, I checked the CKC site as you recommended below. The guidance on the C-tick mark to which you refer is out-of-date. CKC's document is based on the July 1995 edition of the EMC Frameworks. The SMA made major amendments to the Framework in March 1996. One of these revisions

Thanks for the word, Dave. I will know not to rely on the printed material they supply, then. Sic transit tyrannosaurus, right? Cortland __ Reply Separator _ Subject: Re: C-Tick mark Author: Dave

Re: C-Tick mark

All, I have found several test lab on-line guides with the same out-dated info on use of the C-Tick, CKC's being one of them. The best bet is to stick with SMA. I e-mailed a request to SMA on Monday and got a satisfactory response on Tuesday. Their e-mail address is conveniently accessed

Mark, You may want to check EN 418 'Functional Aspect of Machine Emergency Stop Equipment.' In it, it does cover some of the constructional requirements noted in your email. Particularly, 4.4.1 The emergency stop actuators shall be designed for easy actuation by the operator and others who

Re: How the limits determined?

I will have to go back to my records, in which I have a copy of the FCC's NPRM setting up Class A and B limits, but as I recall, limits were established by reference to the response of radio and television users to known levels of radio noise. Also, impulses of known energy and PRF

Re: How the limits determined?

You need a copy of the FCC 79-555 report and order of 1979 implementing the regulation of digital devices. Appendix C is titled Derivation of Limit for Class B Computing Device. The class A limit was derived from CBEMA proposal CBEMA/ESC5/77/29 which was also submitted to CISPR. I would be

Re: C-Tick mark

Bill, I feel a bit like a PR rep. for Standards Australia and the SMA today. Both the C-tick and the RCM are available as software and hard copy format from Standards Australia. The catch is that you need to supply a copy of an authorization to use the mark from the relevant regulator.
