How well do you know a genuine ISI Mark:

The BIS Standard Mark (ISI Mark) is a quality mark.

This is a certification mark of the bureau of Indian standards (BIS), which was earlier called the Indian standards institution (ISI).

Most consumers prefer ISI Marked products. With the growing demand of ISI marked products, the instance of misuse of ISI Mark is also on the rise.

Unscrupulous manufacturers are trying to cheat the consumers by marking products with ISI Mark without obtaining the valid licence from BIS.

Every ISI symbol has a 7-digit number below it.

Now the 7-digit number is tricky. You pay attention to the first five digits only. And work backwards.

You start with the 5th digit. Multiply that by 1 Then go to the 4th, multiply that by 2. Next comes, yes, the 3rd digit - multiply that by 3. Mulitply the 2nd  digit by 4 and the  1st digit by 5.

Then you add all the numbers you get. The total will be the exact same number as the last two digits.

Take this number as an example: ISI 7 9 0 9 3 9 2

3 x 1 = 3; 9 x 2 = 18; 0 x 3 = 0; 9 x 4 = 36; 7 x 5 = 35;

Add 3+18+0+36+35 = 92

And there you have it, unless the fake ISI symbol makers can do basic math themselves and create a plausible number.

One important fact to remember is that if a product is popular, you can be sure there will be a lot of fakes made.

The smart thing to do, is to always buy your products from a credible and reliable outlets. Get a receipt and keep it. If you find that the product bears a fake ISI mark and then send your complaints by logging on to www.bis.org.in or report it to ddgenf@bis.org.in.
