Pokey

Tom I recently visited a site that had 2 hinges fitted to a brand new FD30, the FM argued that 2 hinges were complaint. Although the hinges where CE BS 1935 marked I was not happy with them as they did not look wright and there was no sign of any intrumisent pads under the hinges so I stood by my decision. I have since found ou that one of the pins had fallen out of the hinge and the door was found hanging by the bottom hing! My question is when is it appropriate to use just 2 hinges and is this a old or new regulation.
