M-501 Surface protection and protective coating (2022)

The main changes from edition 6 are an update of the technical content based on experience, new requirements and new international standards. 

  • Advises coatings systems that can meet the high durability range as per ISO 12944-1
  • Defines the corrosivity categories accounted for as per ISO 12944-2
  • Includes pre-qualification requirements for coating under insulation and for tank linings
  • Clarifies the qualification requirements for paint shops and operators
  • Clarifies the inspection and testing requirements that apply before, during and after coating application
  • Captures improvements from IOGP doc S-715
  • Introduces new coating systems to cover cryogenic conditions, high temperature service, powder coating and passive fire protection (PFP) in splash zone 

New content

New sections are implemented to cover: 

  • Coating repairs
  • Quality management and performance assurance
  • Coating selection tables 

New normative annexes are implemented to cover: 

  • Water uptake for PFP
  • Immersion freeze dry testing for PFP
  • Fire testing for PFP
  • Adhesion/cohesion test 

New informative annexes are Implemented to cover: 

  • Test panel for Coating Procedure Tests (CPT)
  • Coating operator qualification test
  • Overlapping zones
  • Maintenance coating 

New separate CSDS 

  • Test panel for Coating Procedure Tests (CPT)
  • Coating operator qualification test
  • Overlapping zones
  • Maintenance coating 

A separate coating system data sheet (CSDS) for each coating system and substrate is developed. This includes new systems related to: 

  • Buried in soil PFP in splash zone
  • Cryogenic service
  • High temperature service
  • Powder coating 

A separate coating system data sheet (CSDS) for each coating system and substrate is developed. This includes new systems related to the activities in table 1 (re pre-qualification of systems) and 2 (Inspection and testing requirements) are numbered for easy cross reference in each CSDS.

Each CSDS outlines the relevant operational conditions, applicable substrate material quality, surface preparation requirements, generic coating system build up and the required adhesion testing. In addition, it gives cross references to any pre-qualification requirements and to all test and inspection activities to be carried out.
