Our Instrumentation

CSI prides itself on being able to provide non-opinionated conclusions based on the fact that we have the ability to objectively measure 99% of all fairing/coating aspects during and after application works, including post project delivery measurements.

With the accumulated data, a comparison is made to the agreed contractual specifications and/or manufacturer data parameters which therefore objectively
determines whether the fairing/coating system is applied or is performing in accordance with these specifications, or not.

Inspection methods, processes, their standards, instrumentations and desired objectives can be largely categorized between: Cosmetic and Technical inspections. For the purpose of having a better understanding of the intricacies between the two, we have listed some of the instrumentation used by CSI for these two inspections:

Cosmetic appearance quality assessment

  • BYK Gardner dual wave scan for the accumulation of measurable data such as but not limited to: Distinction of Image, orange peel, dullness, Wd etc
  • BYK Gardner Tri-Gloss for the accumulation of measurable data regarding Gloss Units of high gloss, semi-gloss and flat finishes at 20, 60 and 85 degree angles.
  • BYK Gardner Spectro Guide 45/0 for the accumulation of measurable data regarding color, opacity and color comparison.
  • Digi-scan for close surface microscope capturing of surface irregularities.

Technical application process quality assessment

  • Cross Hatch adhesion test to verify inter-coating bond adhesion between the topcoat/primer layers and underlying epoxy fairing compound systems or other.
  • Shore D hardness test to verify the hardness of applied fairing layers in order to determine whether mixing ratio and cure are within manufacturer’s specification.
  • Dolly bond adhesion test to verify the adhesion value between a substrate and first substrate primer and/or bond adhesion values between layers of applied epoxy fairing compounds in accordance with the manufacturer specification.
  • P.I.G. Paint Inspection Gauge to destructively measure dry film thickness of individual and combined paint film layers to determine compliance with manufacturer specifications.
  • Ultra Sonic test instruments to non-destructively measure dry film thickness of individual and combined paint film layers (including epoxy fairing compound up to 2 inches) to determine compliance with manufacturer specifications.
  • Surface cleanliness tests such as the Bresle test to verify surface cleanliness prior to application of the first substrate primer below and above the waterline.
  • Surface roughness profile testing for blasted surfaces by means of Testex tape method.
  • Mitutoya Rmax surface profile test measurements for sanded surfaces prior to application of varnishes, primers and topcoats.
  • Pencil hardness test to determine whether the applied topcoat finish is in accordance with manufacturer specification for full 100% correct cure cycle, hardness, mechanical resistance etc.
  • Inspection lights whether Ultra Violet for blasted surfaces to determine surface contaminants such as organic fats and alkaline, High Lumen standard inspection lights or or 3M Sun Gun to create “natural day light” for color and finishes inspections.
  • Climatic condition test equipment to determine ambient and surface temperature, dew point, relative humidity etc.
  • Airflow test to determine whether the CME structure surrounding the project has a correct air flow throughout which will avoid “dead spots” causing airborne surface contaminations such as overspray, dust particles etc.
  • Air cleanliness test to verify that overall 100% clean air is used throughout the project to avoid imbedded contaminations within the fairing/coating layers
  • Electro static air test to determine whether a surface is 100% free of an electrical surface charge which can negatively influence applications and cause “air to surface” contaminations.
