D3843-16 – Standard Test Method Technical Guide
ASTM D3843-16 (Reapproved 2021) establishes quality assurance requirements for protective coatings applied to nuclear facilities. It specifically applies to Coating Service Level I areas as defined in Guide D5144, replacing the former ANSI N101.4 standard while incorporating technological advancements and updated industry practices. This standard is essential for ensuring the safety and reliability of protective coating work in nuclear power plants.
📋 Scope and Applicability
The scope of D3843-16 covers quality assurance requirements for safety-related protective coating work in nuclear facilities. It provides a common basis for coating work in Coating Service Level I areas. The standard does not address all safety concerns; users are responsible for establishing appropriate safety, health, and environmental practices. It was developed in accordance with international standardization principles.

📚 Quality Assurance Framework and Referenced Documents
D3843-16 references several ASTM standards for specific quality assurance functions. Practices D4227 and D4228 provide qualification criteria for coating applicators on concrete and steel surfaces, respectively. Guide D4537 outlines procedures for qualifying inspection personnel. The standard aligns with broader quality assurance programs such as ANSI N45.2 and ASME NQA-1. Key regulatory requirements from 10 CFR 50 Appendix B and 10 CFR 21 are also incorporated. Terminology used in this standard is defined in Terminology D4538 or within the standard itself; for instance, a “project specification” is a written document designed to ensure execution of coating work for a project.
⚠️ Note: An editorial update in February 2021 revised Section 2 (Referenced Documents) and Section 6 of this standard. Users should ensure they are working with the latest version.
✅ Compliance Tip: By meeting the requirements of D3843-16, organizations also satisfy the quality assurance criteria of ANSI N101.4, making this standard a comprehensive update for nuclear coating work.
