New Ipad & Iphone 4S charging voltages

Hi, I have a 3rd party iphone charger which supplies 5.2 volts. It charges the iphone 4s alright but cannot charge (charging symbol is not shown on screen) on the new ipad. With a multimeter I measured the original chargers' outputs. They vary between 5.12-5.15 voltages for both of the devices. So, my first question is whether you know which smart apple technician decided that so little deviation from the standard is not acceptable Secondly, do you know what are the extra voltage tolerances for both of the devices? (Apparently, they are less than 2 percent) Cheers!
