On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high temperatures or …read more Continue reading Humble Arduino As PLC
We’ve seen a number of heart rate monitoring projects on Hackaday, but [Peter’s] electrocardiography (ECG) Instructable really caught out attention. If you’ve followed Hackaday for any period of time, you’re …read more Continue reading ECG Project With All the Messy Safety Details
Information security standards such as those developed and published by the ISO (International Organization for Standardization) might not be enshrined in law, but that doesn’t mean they should be viewed as a ‘nice to have’ or an afte… Continue reading Strictly private: Why ISO 27001 is a big deal
In an earlier article, I covered Fire Hazard Tests that form an important part of safety testing for electronic/electrical products. We looked at the standards and equipment used for abnormal heat, glowing wire and flame tests. A typical compliance test report for an appliance, such as a toaster, will be a fairly long document reporting the results for a large number of tests. Among these, the section for “Heat and Fire” will usually have the results of a third test – Tracking. It’s a phenomena most of us have observed, but needs some explanation to understand what it means. …read more
How do you know that new appliance you bought won’t burn your house down? Take a look at any electrical appliance, and you’ll find it marked with at least one, and most often, several safety certification marks such as UL, DIN, VDE, CSA or BSI. Practically every electrical product that plugs into utility supply needs to go through a mandatory certification process to ensure it meets these conformity test requirements. Some examples include domestic and industrial electrical appliances, tools, electrical accessories, consumer electronics and medical electronics.

The International Electrotechnical Commission (IEC) is an international body that issues standards on a wide range of electronics-related topics. How wide? Their mandate seems to span rules for household product safety to the specification of safety logic assemblies in nuclear power plants. Want to know how to electrically measure sound loudness? Test methods for digital door lock systems? Or maybe you’re interested in safety interlock systems for laser processing machines. There’s an IEC standard for that too.
Unfortunately, this information is kept behind a paywall. OK, it’s a lot more like a pay fortress. They really, really don’t want you …read more
After months of cross-disciplinary meetings, some of the largest professional associations just announced their plans to submit an entire standard set for engineers with egos too fragile to accept design criticism. The Special Snowflake Standard or S2 (in compliance with Godwin’s law) ensures compromised mechanical and electrical integrity by ignoring proper design methodologies for more fluid definitions of success. The Special Snowflake Standard allows the modern engineer greater flexibility in avoiding self-improvement in their field while maintaining an advanced level of apparent competency.
The Standard follows an ingenious randomly generated naming scheme to hinder cross-checking and look-up. The honesty …read more
