A Deep Dive into Nash’s Testing Methods

Everything we manufacture - whether it’s a high-performance compressor, a precision-engineered vacuum system, or a custom-built pump - must meet exacting standards. The tolerances are tight. The materials are specialized. And the performance must be flawless. Quality assurance plays a critical role in verifying that every component, every weld, every test result aligns with what the customer expects and what the application demands.

Without robust QA, we risk delivering equipment that doesn’t perform under pressure, that corrodes too quickly, or that fails during critical operations. And in engineer-to-order environments, where every product is unique, the stakes are even higher.

Comprehensive Testing & Inspection at Nash

That’s why we rely on a comprehensive set of testing and inspection methods— each designed to validate a specific aspect of quality, safety, and compliance:

At Nash, every order is supported by a detailed Inspection and Test Plan (ITP), aligned with customer specifications and internationally recognized standards such as API, DIN EN ISO, or ASME. These plans cover the entire execution process, from incoming material verification, through manufacturing and assembly, to final Factory Acceptance Tests (FAT).

Our QA team ensures that each requirement is captured and converted into clear test instructions and procedures. This includes non-destructive examinations (such as LPT, UT, RT, and PMI verification), destructive tests where applicable, and performance checks during FAT. Each stage is carefully reviewed, documented, and verified against the customer’s approved acceptance criteria.

Importantly, all products produced at Nash are tested, even if no specific customer request is made. This proactive approach guarantees that performance, safety, and reliability are validated before delivery. Customers or their representatives are welcome to attend inspections at different stages, ensuring full transparency and confidence in the results.

By combining rigorous testing with clear documentation, we eliminate surprises later in the project. Every test result is recorded, signed off, and reviewed, giving customers assurance that the product they receive will perform exactly as intended, without compromise.

Collaboration in Action: QA, Test Field & Customer

At Nash, quality assurance is a team effort. From the moment a test is scheduled, our QA team works closely with the test field and the customer to align on expectations, witness points, and documentation. This ensures that every requirement - no matter how specific - is understood and planned for.

During testing, whether it’s a Factory Acceptance Test or Positive Material Identification, the customer is often present to witness the process firsthand. This transparency builds trust and allows for immediate feedback. In one recent case, a customer’s specification conflicted with the physical design of the product. Instead of delaying the project, we collaborated on-site to propose a compliant, practical solution - one that was accepted and documented on the spot.

After testing, all results are reviewed, signed off, and compiled into the final quality dossier. When needed, we also coordinate with third-party agencies or notified bodies to ensure full regulatory compliance.

This hands-on, transparent approach is how we turn complex requirements into reliable, certified products—every time.

Quality Isn’t Just about Passing Tests. It’s about Building Trust

At Nash, quality assurance is more than a checklist. It’s a commitment. Every test we run, every inspection we perform, and every collaboration we foster is driven by one goal: earning and keeping our customers’ trust. Because when lives, operations, and reputations depend on our equipment, “good enough” simply isn’t good enough.
