Several of the recently formed Standards Committees (SCs) are working in various areas to produce new standards, technical reports, and guides, as well as welcoming AMPP members and nonmembers to join SCs that fit their interests and expertise.
Performance Test Methods for Offshore Protective Coating Systems
SC 03, External Coatings—Buried and Immersed has launched TM21612—Performance Test Methods for Offshore Protective Coating Systems. Set for publication in December 2022, the scope of this new test standard is to specify the coating systems, surface preparation, and test methods. The test methods include rust creepage, edge coverage, thermal cycling, seawater immersion, and cathodic disbondment. The coating systems cover atmospheric zone, splash zone, and tank lining immersion zone. The test time is only 12 weeks, which is much shorter than the ISO 12944-9 standard. This new standard is more economic and more effective to help facility owners select the proper coating system for their offshore structures. It also helps coating manufacturers to develop new coating systems for the offshore market.

Corrosion Testing for Additive Manufacturing
SC 08, Metallic Material Selection & Testing announces a new project designated as TR21522—Corrosion Testing for Additive Manufacturing. According to the scope, the committee will create a technical report that presents the current state of knowledge and gap analysis on corrosion testing for products that are manufactured using additive manufacturing (AM) processes. The surface condition and residual stress are recognized variables that are not sufficiently detailed and that are necessary for the assessment of performance of AM products. The finished report, scheduled for December 2022, will contain recommendations for test details that are relevant to the AM processes and provide the foundation for the preparation of test standard(s) that apply to AM.

Facilities Integrity Corrosion Management and Asset Selection
SC 10, Asset Integrity Management has launched SP21521—Facilities Integrity Corrosion Management and Asset Selection. The scope of this document is to cover methods for corrosion management and asset selection for inspection using trending data, system data, and best practices for liquid hydrocarbons. This will help drive more efficient asset inspections to target the assets needing attention first. Some items that can be covered are:
- Facilities asset management principles
- Using trending data to predict threat (corrosion) behavior by asset type
- Effectiveness and efficiency and performance metrics
- Reliability modeling principles
- Making adjustment to the current program and planning for future inspections
The standard, scheduled for publication in October 2022, can complement recommended practice API 2611, Terminal Piping Inspection—Inspection of In‐Service Terminal Piping Systems.

Acceptance Criteria for Cathodic Protection of Steel in Concrete Structures
SC 12, Concrete Infrastructure announces a new project designated as SP21520—Acceptance Criteria for Cathodic Protection of Steel in Concrete Structures. This standard practice will cover acceptance criteria for cathodic protection of steel in concrete in a single document. The expected publication date is in May 2025.

Achieving & Maintaining a Saturated Surface Dry (SSD) Condition on Concrete Substrates
SC 12, Concrete Infrastructure is also launching SP21519—Achieving & Maintaining a Saturated Surface Dry (SSD) Condition on Concrete Substrates. This standard will provide users and specifiers with the best ways to achieve and maintain SSD conditions of concrete surfaces during and post application of cementitious repair mortars. The goal is to standardize the process and wording so there are no misconceptions or misunderstandings on projects and specifications.
This standard will include best practices for environmental conditions during application and discuss areas and alternatives when SSD may not be achievable due to adverse (arid/very dry) environmental factors. The standard/guideline should detail processes and equipment available for achieving SSD as well as the equipment, materials, and processes available for maintaining SSD.
This document will clarify what an SSD surface looks like and how to detect it when the condition has been reached. It will also contain standardized guidelines on how to maintain the condition working throughout a project to ensure cementitious repair materials are always applied to an SSD conditioned surface. It is scheduled for publication in October 2022.

Standard Guide for Improving the Precision of Dry Coating Thickness Measurements on Ferrous and Non-ferrous Metal Substrates Using Continuous Read/Scanning Technology
SC 23 will produce Guide 21614, Standard Guide for Improving the Precision of Dry Coating Thickness Measurements on Ferrous and Non-ferrous Metal Substrates Using Continuous Read/Scanning Technology.
The statistical analysis of data (based on research and a technical paper presented by Jeff O’Dell, Vision Point Systems, at the SSPC 2017 National Conference) suggests that greater precision of dry film thickness (DFT) measurements can be achieved by obtaining a greater population of measurements over a larger area using the scanning method over the traditional “place and remove probe” frequency described in Section 8 of the current version of the SSPC-PA 2 standard. Also, scanning technology enables an operator to collect a greater number of DFT measurements in a shorter time frame than the traditional “place and remove probe” method. Due to the increased number of measurements being collected, better indication of the sample mean can be obtained through increased precision. The expected publication date is in January 2023.
