Quality, Testing & Standards
Verify the Coating, Not Just the Colour
PPC combines an ISO 9001:2015 quality system with in-house inspection and standards-based testing so coating requirements can be tied to measurable acceptance criteria.
A coating specification is strongest when the preparation, application, cure and inspection requirements are defined together. PPC reviews the governing drawing, customer specification and purchase order so the quality plan reflects the actual application instead of applying one generic test package to every job.
Testing and inspection capabilities
| Check | What it verifies |
|---|---|
| Film thickness | Confirms coating build against the agreed specification or process requirement. |
| Cure verification | Checks that the coating has reached the required cure condition for the selected system. |
| Adhesion | Evaluates how well the coating remains bonded to the prepared substrate using the specified method. |
| Salt spray / corrosion | Used when a specification calls for accelerated corrosion exposure and defined acceptance criteria. |
| Humidity | Assesses coating response to sustained warm, humid exposure when required. |
| UV / weathering | Supports evaluation of colour, gloss and coating durability for weather-exposed systems. |
| Appearance | Checks colour, gloss, texture, coverage and visible defects against the approved criteria. |
| Material/process checks | May include powder condition, solvent resistance and other process-specific controls. |
Standards framework
Referencing a standards organization is not the same as claiming every project is certified to every standard. PPC follows the methods and acceptance criteria that are actually specified and approved for the job.
ISO 9001:2015
Quality-management framework used to control documented processes and continuous improvement.
ASTM
Project specifications may reference ASTM coating, adhesion, corrosion, thickness or weathering test methods.
AAMA
Architectural aluminum projects may reference AAMA performance requirements appropriate to the specified coating system.
CSA
Canadian projects may include CSA requirements depending on the component and end use.
SSPC / AMPP
Surface-preparation and protective-coating specifications may reference SSPC legacy or current AMPP requirements.
Documentation to define before production
- Drawing and specification revision
- Approved coating manufacturer/system
- Required film-thickness range
- Masking and critical-surface notes
- Test methods and acceptance limits
- Sampling or lot-inspection frequency
- Traceability and report requirements
- Third-party or witness requirements
Frequently asked questions
Is PPC ISO 9001 certified?
PPC operates an ISO 9001:2015 registered quality management system. Project-specific certification, documentation and acceptance requirements should still be identified on the RFQ or purchase order.
Can PPC provide coating test reports?
Yes, when reporting is included in the agreed project scope. Identify the required test method, acceptance limit, sampling frequency and report format during quoting.
Does every project receive every test?
No. Testing is selected from the coating system, customer specification, purchase order and risk of the application. The inspection plan should match the actual acceptance criteria.
Can third-party testing be arranged?
Yes. Where a specification requires independent verification or a test outside PPC's in-house scope, third-party testing can be discussed during project review.
Define acceptance before production starts
Include the governing specification, test methods, acceptance limits and documentation requirements with the RFQ.
