Elcometer 128 Pictorial Surface Standards (part number E128-1) are high quality photographs used for comparison to assess the visual appearance and degree of cleanliness of a steel surface. Surface contamination from salts such as chlorides, sulphates and nitrates has been shown to cause blistering of organic coatings, particularly in immersion conditions, so it is not enough to clean the substrate once. In a multi-layer coating process the cleanliness of each layer must be monitored and recorded before the next coat is applied.
The Elcometer 128 Pictorial Surface Standards work by direct visual comparison: the prepared steel is held against the reference photographs and matched to the level of cleanliness shown. The Elcometer 128 Pictorial Surface Standards illustrate the degree of cleanliness of different levels of rusted steel cleaned by blasting, by hand and power tools, and by flame, as specified by ASTM D2200 Method A. This makes them suited to inter-coating monitoring, which matters when using amine cured epoxy coatings in low ambient temperatures or high humidity, where surface oiliness or exudate can cause inter-coating adhesion failure.
The Elcometer 128 Pictorial Surface Standards conform to BS EN ISO 8501-1:2007 and SIS 055900, the original visual surface cleanliness standard. The Elcometer 128 Pictorial Surface Standards are used by coatings inspectors and applicators in surface preparation, corrosion protection and protective coating work.

Elcometer 128 Pictorial Surface Standards
Elcometer 128 Pictorial Surface Standards are high quality photographs which are used for comparison purposes to assess the visual appearance of a steel surface.
- Surface contamination assessment Measures cleanliness of substrate in multi-layer coating processes to prevent blistering of organic coatings from salts such as chlorides, sulphates and nitrates
- Inter-coating monitoring Monitor and record the cleanliness of each layer prior to applying the next coating, particularly important when using amine cured epoxy coatings in low ambient temperatures or high humidity
- Visual comparison standard High quality photographs used for comparison to assess the visual appearance of steel surface and degree of cleanliness
When to use the Elcometer 128 Pictorial Surface Standards
Judging how clean a blasted or cleaned steel surface is comes down to comparison against a reference. The Elcometer 128 is a set of high quality photographs used to grade the degree of cleanliness of rusted steel cleaned by blasting, hand and power tools or flame, against BS EN ISO 8501-1.
- 1A consistent cleanliness benchmarkComparing the substrate to fixed reference photographs gives a repeatable way to grade cleanliness across different inspectors and shifts, rather than relying on individual judgement.
- 2Records the state before each coatIt lets you monitor and record cleanliness before each layer goes on, which matters with amine cured epoxy coatings applied in low temperatures or high humidity.
- 3Heads off later coating failureAssessing salt contamination such as chlorides, sulphates and nitrates at this stage helps prevent blistering of organic coatings once the structure is in service.
