Together with BlastOne International, GMA conducted a webinar discussion on the changes to the ISO standards – ISO8502-6 & ISO8502-9, which was released in July this year.

These changes crucially recognise that conductivity alone is an inaccurate measure for determining corrosive contaminants and the importance of blank testing.

The webinar held on 28 October 2020 was part of the C&P Online Coatings & Applicators Day which was organised by the Australasian Corrosion Association. The virtual event features technical presentations, interviews, new training opportunities, key product demonstrations and innovative new technologies.

During the discussion, GMA Business Development & Technical Manager- Asia Pacific Julian Anthony and BlastOne Business Development Manager Craig Reynolds discussed the key changes to the updated standards including alternative test methods that should be used as the primary surface preparation test method to ensure optimum coating protection.

This was followed by demonstrations on conductivity and in-field chloride testing using equipment to perform ion specific testing to achieve true corrosive salt readings by GMA Technical Sales Representative, Asia Pacific Saravanan Madavamani and BlastOne Technical Service & Training Manager, APAC Andrew Russell.
