Re: [PSES] Strain Relief Test (SEMI S2)

I'll have to query them on this.‎Thanks, Doug

Re: [PSES] Strain Relief Test (SEMI S2)

What version of S2 does your Customer want you to use? The current version is SEMI S2-0715 and it does not have a strain relief requirement. Neither does S2-0706. SEMI S22-0715 does. Paragraph 17.7.3 in S22 references the strain relief test in paragraph 22.7. Ron Wellman From: Doug

Re: [PSES] Strain Relief Test (SEMI S2)

The latest version apparently has this requirement. I personally have SEMI S2-0706 and have not been able to verify, however the client has indicated the problem with snippets of text from the standard.Thanks,  

Re: [PSES] Strain Relief Test (SEMI S2)

I believe you mean clause 22.7 from SEMI S22? SEMI S2 does not have a requirement for strain relief. Besides, I am wondering why you are using SEMI S22? SEMI S22 was created to be a reference document for SEMI S2. I also agree with the other responses, use an appliance inlet. Ron

Re: [PSES] Strain Relief Test (SEMI S2)

Yes, I suggested an IEC 320 type, the problem is this is a few pennies more expensive than a plastic strain relief.I've given them a few options.  Meanwhile, I ‎need to notify the S2 WG of this oversight.

[PSES] Strain Relief Test (SEMI S2)

All, Is anyone on the forum able to help with a concern about clause 22.7 Strain Relief Test? It requires a calibrated weight of 156 Newtons (35 Lbs) be applied without regard to the overall size of the equipment. For example, a small instrument connected with cord and strain relief requires

Hello Brian, I think that the Technical Program Committee (TPC) has expanded its range of interests for presentations. I'm sorry you had a bad experience with your previous submittals. However, with software and programming becoming a bigger part of safety, there should be new interest in the

You do not need a substitution measurement below 30 MHz since the limits are defined as dBµA/m Regards, Deniz From: Grace Lin [mailto:graceli...@gmail.com] Sent: Thursday, July 07, 2016 11:44 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] EN 300 330-1/-2 Signal Substitution Dear Members,

[PSES] EN 300 330-1/-2 Signal Substitution

Dear Members, Is signal substitution method (SSM) a must for emission testing per EN 300 330-1? Is there any alternative method acceptable? What type of loop antennas can be used as a substitution antenna? Can any passive loop antenna be used as s substitution antenna? Is there any active

[PSES] software safety

Software safety... what is it? At the very least, it is software control of a safeguard. In printers, software shuts down the moving parts when the cover is opened. In CD drives, software shuts down the spinning disc and turns off the laser. No, these shut-downs are not done with a physical

Greetings Mr. Ted of Eckert, Have previously commented in this venue, using nauseating and pedantic detail, why the Therac incident is poor example (the root cause was incorrect design specification and poor management ethics) for teaching the discipline of code testing and software safety

Re: [PSES] Electronic versions of standards and DRM - off topic

True, and seems to be a recurring problem with the coverage of software "engineering". While am a reasonably competent code monkey, and do a passable job at compliance and other stuff, have never had the luxury of time or environment that would allow an assumption of depth and expertise in any

Re: [PSES] Electronic versions of standards and DRM - off topic

Hello Brian, ISPCE has had some coverage of code safety, but it is typically in the medical track. This is one area where code review has been standard for some time. However, I have found attendance for the medical presentations to be among the lowest for any of the ISPCE presentations.
