I don't think there is a standard for Error-proof devices. But according to article 10.2.4 of the IATF 16949.2016 standard; Both production and product verification methods of error-proof devices must be specified in the control plan. For example, let's assume that there is 100% control of the product on the production line with a camera. You verify this camera with the "NOK" master sample per shift. Here in the control plan, you need to enter the verification of each shift with the "NOK" master sample.
