Japan to Discourage Sale of Old Electronics

devphaeton writes to tell us Engadget is reporting that after April 1st (no this is not an April fools joke) the sale of old electronics in Japan could become much harder. From the article: "It seems that Japan's government revised its "Electrical Appliance and Material Safety Law" back in April 2001, and added a stipulation that items authorized under the country's old law (the "Electrical Appliance and Material Control Law") couldn't be sold anymore, but granted those products a five-year grace period. Well, if you check your convenient wall calendar, you'll see that the five-year period is about to end, which means that as of April 1, pretty much any electronic gear sold before April 1, 2001 can't be legally resold in Japan." The article also mentions that sellers can continue to sell old gear providing they get certification that the items conform to modern safety standards.

Only retail

This is only retail sales, not individuals. And it isn't a ban, it merely requires the retailer to take responsibility that the device is safe according to the new standard. And it involves only the safety of high-voltage (mains-powered) equipment, not electronics.

As has been pointed out, this only applies to old electronics that connect to MAINS circuits (e.g. wall outlets, which are 100 VAC RMS in Japan IIRC).

Category II circuit, such as MAINS, as defined by IEC and (in the US) Underwriter's Laboratories, must be designed to tolerate overvoltage conditions such as those caused by transformer shorts or relatively distant lightning strikes. From UL 3121-1, a circuit designed with a working voltage of 100 V DC or AC RMS must tolerate a peak impulse voltage of 1360 V for a few microseconds (from table D.10). This doesn't necessarily mean that the product still has to work after such an impulse; it just means that the product must remain safe to the operator for such an impulse. Fuses can blow, chips can be damaged, but no voltage greater than 60 V DC / 42.4 V AC pk can be exposed to the user.

I assume that Japan's old standard, before 2001, was weaker than this. Thus, older electronics can't be sold because they could theoretically kill the users.

This only applies to products that carried MAINS voltages. (Products with wall-warts limit the high voltage to the wall, and are completely unaffected.) Even then, the old products might have been designed above the standard, and therefore could still be sold anyway.

(Disclaimer: I design high voltage hardware products.)
