Quality Assurance: An Expert's Guide to Coating Inspection for Regulatory Compliance

by Alexander Bartholomew Knower of things

Coating inspectors must possess an excellent knowledge of their inspection instruments (with regular calibration). Inspectors also need to understand the purpose and procedures for using test kits and visual guides. Effective communication - both written and verbal - is vital in order to resolve disputes between the contractor superintendent and the nace certified coating inspector.

1. Preparation

Quality Assurance (QA) processes are designed to identify potential defects in advance by pinpointing inefficiencies in the approaches, techniques, and methods utilized for projects. These processes act as an early warning system, preceding Quality Control (QC) checks on their implementation.

Coating inspections are indispensable tools in assessing whether contractors have fulfilled project specifications. This is particularly vital in industries such as aerospace and power generation, where substandard coating jobs can lead to disastrous structural failures, expensive equipment breakdowns, and dangerous work environments.

QA inspectors are usually responsible for creating an inspection plan which outlines what and how should be inspected as well as any acceptance criteria from a specification. This task can be extremely complex and requires in-depth knowledge of requirements for both specifications and nondestructive test methods (NDT), correctly recording QC data and understanding industry standards such as SSPC-SP 10 Near-White Abrasive Blast Cleaning as well as PA 2 Procedure for Determining Conformance to Dry Coating Thickness Requirements as well as many others.

2. Inspection

Coating inspectors require various skills. These include physical abilities such as climbing and entering restricted spaces, clear vision with corrective eyewear, keen sense of smell, manual dexterity to use or manipulate inspection instruments and understanding their general responsibilities and understanding industry standards (SSPC-SP 10 Near White Abrasive Blast Cleaning and SSPC-PA 2 Procedure for Determining Conformance to Dry Coating Thickness Requirements are two examples).

Inspectors' tasks involve reading through project specifications to extract inspection hold points and acceptance criteria, and creating an inspection plan to fulfill quality assurance duties on the work. A carefully documented inspection plan can protect project owners against premature coating failure claims or potential liability issues; this one-hour webinar will explore how to prepare one for steel structure or concrete coating and liner projects.

3. Tests

Quality assurance is an effective way for businesses to deliver an outstanding customer experience, and can help ensure you're providing high-quality services. This may involve making sure all employees follow company standards for customer experience as well as identifying areas for improvements.

Coating inspectors must possess the ability to conduct various tests, including dry film thickness readings (which must be obtained at five locations every 9 m2 or 100 ft2), surface profile measurements and requirements, differences between rust back and staining, use of visual aids as well as climbing into tight spaces while remaining exposed to harsh environments.

Initial training for coating inspectors is important, but just as essential is developing an impeccable work ethic and being able to uphold specifications without favoritism or bias. According to SSPC's The Inspection of Coatings and Linings manual, on-the-job training should preferably occur under the watchful eyes of an experienced inspector who monitors trainee work to make sure standard test procedures are being observed by trainees.

4. Reporting

Coating inspectors must fulfill their responsibility of meeting specification requirements and gathering accurate inspection data, which requires having an in-depth knowledge of how to operate and calibrate inspection instruments, visual guides, and test kits.

Coating inspectors must possess exceptional verbal and written communication skills, in order to effectively relay issues and concerns to facility owners, specifiers, contractors superintendents in a professional and courteous manner.

Experienced coating inspectors tend to be better equipped than newer inspectors in handling the unexpected situations that may arise on a project. Leveraging their learned knowledge, industry standards, and experience, experienced inspectors can draw upon these resources in order to resolve problems a newer inspector might struggle with. Over time they gain the ability to adapt quickly - one of the most sought after characteristics for any inspector. Learn more from https://youtu.be/gxANBtRJE5g
