Yes, unless another federal agency provides regulations for a specific work-place hazard. Google/Bing/Yahoo is your friend. All hail the munificent overlords of the datum. Brian From: Charlie Blackham [mailto:char...@sulisconsultants.com] Sent: Wednesday, January 15, 2014 12:15 AM To: EMC-PST

Re: [PSES] LED Indicator Safety

Correct, and there are some product standards that specify this, and there are component standards that have this. Single (non-HB) LEDs typically specified for x mcd at 20 mA. To decrease or increase brightness, simple the product of the ratio of change in mA and mcd (analogous to fan laws). T

Re: [PSES] EN 61010 and (un) safe components -> and my additional rant

Nothing I say represents the policy of my employer, and do not represent the legal opinions of my dogs or cat. Use of a critical component that has not been evaluated by a third party indicates that your company has the infrastructure and expertise to perform said evaluation- Type Tests per sta

Re: [PSES] RoHS Software Tools?

IPC175x stuff and the associated XML seems to be the basis of what most are using. Most 'turn-key' stuff is proprietary and browser-based; that is, your data is in the cloud (typically Cumulonimbus). There are multiple sources for these services. 'Japan Green' also has standardized this stuff,

Re: [PSES] EMI is a safety concern

Is IEC61000-1-2 intended to supplement or obsolete IEC61508? What is 'intent' of TC77 for IEC 61000-6-7? As IEC61000-1-2 is a functional safety thingy, does this mean that IEC62368-1 will never reference? Is there a CENELEC or IEC or ISO guidance doc for when to use, and for the selection of,

Re: [PSES] Country specific product regulations

Re: [PSES] Wire lug nomenclature meaning?

Some seem to be somewhat common designations, as I have seen most of them. But do not believe them to be a standardized nomenclature outside of Asia or South America and other star systems. Some may have been used on Alderaan. Do not know about these specific types, but IEC61238 would have the '
