ISO
The following documents have obtained substantial support within the appropriate ISO technical committees during the past two months and have been submitted to the ISO member bodies for voting, or formal approval.
ISO/PRF 1460 Metallic coatings — Hot dip galvanized coatings on ferrous materials — Gravimetric determination of the mass per unit area (revision of 1992 standard)
ISO/DIS 7539-9 Corrosion of metals and alloys — Stress corrosion testing — Part 9: Preparation and use of pre-cracked specimens for tests under rising load or rising displacement (revision on 2003 standard)
ISO/PRF 11127-1 Preparation of steel substrates before application of paints and related products — Test methods for non-metallic blast-cleaning abrasives — Part 1: Sampling, Part 2: Determination of particle size distribution, Part 3: Determination of apparent density, Part 4: Assessment of hardness by a glass slide test, Part 5: Determination of moisture, Part 8: Field determination of water-soluble chlorides (revision of 2011 standards)
ISO/DIS 18797-2 Petroleum, petrochemical and natural gas industries – External corrosion protection of risers by coatings and linings — Part 2: Maintenance and field repair coatings for riser pipes
ISO/FDIS 23449 Corrosion of metals and alloys — Multielectrode arrays for corrosion measurement
ISO/DIS 7539-9 Corrosion of metals and alloys — Stress corrosion testing — Part 9: Preparation and use of pre-cracked specimens for tests under rising load or rising displacement (revision of 2003 standard)
New international standards published during the past two months
ISO 23363:2020 Electrodeposited coatings and related finishes — Electroless Ni-P-ceramic composite coatings
CEN
Standards published within last two months.
EN ISO 8502-9:2020 Preparation of steel substrates before application of paints and related products – Tests for the assessment of surface cleanliness – Part 9: Field method for the conductometric determination of water-soluble salts
This document specifies a field method for the assessment of the surface density of various water-soluble salts on steel surfaces, before and/or after surface preparation, by conductometric determination. The individual surface densities of the salt cannot be determined by this method, as it assesses only contaminants that form an electrolyte (ions) when in contact with water
EN ISO 11463:2020 Corrosion of metals and alloys – Guidelines for the evaluation of pitting corrosion
This document gives guidelines for the selection of procedures that can be used in the identification and examination of corrosion pits and in the evaluation of pitting corrosion and pit growth rate.
The review was published in Progress in Organic Coatings, Volume 146, September 2020.
