text: For example, if you hold Ultrasonic Welds PCN Level 2 Plate and Pipe which expires by 10th January 2017, you can take the supplementary Node exam up to the end of November 2016.
  From 1st July 2017, PCN requires that the Supplementary exam is taken 6 months prior to the expiry of relevant PCN Certificates. So, if the PCN Certificate expires in mid-July 2017 then the Supplementary exam must be taken by mid-January, which means booking the exam needs to be made by November 2016.
  Please take a look at your Certification Record and if you are considering adding Supplementary examinations then you are advised to note these changes by PCN. If you have any questions on this or other Certification matters, then please contact us and we will do our best to assist you.
