Important changes to EN 13697

The latest update, EN 13697:2015+A1:2019, has now been published. Amongst the changes are some important ones, which may require you to have further testing done on your products.

  1. The interfering substance for testing against Pseudomonas aeruginosa, under clean conditions, has now been reverted to 0.3 g/l bovine albumin.
    In line with ECHA guidance, prior to this revision, we had already made this change and included a note in test reports as justification. However,
  2. The 2019 amendment has also changed the way in which both Pseudomonas aeruginosa and Candida albicans test suspensions are prepared. Both must now be prepared 10x stronger than in previous versions.

Tests done to EN 13697:2015 are still valid, with the exception of any tests done against Pseudomonas aeruginosa or Candida albicans under clean conditions.
This applies if even if the clean conditions (for Pseudomonas aeruginosa) had been amended to 0.3 g/l bovine albumin, in accordance with ECHA guidance.
