10.0 INSPECTION
10.1. All work and materials supplied under this specification guideline shall be subject to competent
and timely inspection by the contractor or his authorized representative.
10.2. The contractor shall, throughout the course of the coating work described in this specification

and the Project/Job Specification.
10.3. Mandatory inspections shall be conducted to determine compliance with the "hold points" detailed
in the Project/Job Specification, and "signed off" in the areas provided.
10.4. Inspections shall be conducted, a minimum of four (4) times per shift, or more frequently when
coating work operations or changing environmental conditions require particular surveillance.
10.5. Cured coating shall be tested for holidays (pin holes) using a high-voltage DC holiday detector or
equivalent instrument adjusted and operated in accordance with ASTM D5162-91(B),
Discontinuity (Holiday) Testing of Non-conductive Protective Coating on Metallic Substrates.
Irathane 155 can be tested at a rate of 100 volts/mil. All holidays should be repaired in

substrate, temperature and humidity of ventilating air, batch numbers and identification of mixed
coating components, wet film thickness or application rate of individual coats, dry film thickness of
individual coats, recoat intervals, Location and repair of pinholes and determination of degree of
