PBSC’s Approach to FQT and FAT

Why testing matters: guaranteeing reliability, compliance and smooth starts

At PBSC Ltd, we know that when you specify cleanroom, high containment or material decontamination solutions, you want equipment that works reliably from day one. That is why every item undergoes Factory Quality Testing (FQT), our internal process to ensure it meets PBSC’s engineering and safety standards.

For projects where reliability, compliance and uninterrupted operation are essential, we also offer Factory Assurance Tests (FATs). FATs check performance against client specifications before equipment leaves our facility. Together, FQT and FAT provide a comprehensive approach that gives you confidence the equipment will perform as required from day one.

Internal FQT: our mandatory baseline checks to ensure safe dispatch

Before any Factory Assurance Test is carried out, every unit manufactured by PBSC undergoes rigorous Factory Quality Testing. Unlike FATs, which are tailored to client specifications and project needs, FQT is mandatory for all equipment leaving our facility.

Our FQT process ensures:

Standardised quality checks – Every unit is tested against PBSC’s internal benchmarks to confirm it meets engineering and safety standards.
Functional verification – Core functions and control systems are verified before client-specific testing begins.
Reliability and safety – Issues are detected and resolved internally so equipment is safe, stable and ready for FAT or dispatch.
Consistency across products – Whether a standard pass-through hatch or a bespoke high-containment system, every product receives the same internal scrutiny.

By combining mandatory FQT with optional FATs tailored to your project, PBSC delivers equipment that is built to specification and proven reliable before it reaches your site.

Factory Assurance Tests (FAT): client-specific validation before delivery

In regulated sectors such as pharmaceuticals and high containment research, FATs are often required by contract or recommended by industry standards. Even when not mandatory, we advise clients and specifiers to consider FATs. They provide reassurance that equipment will perform as expected and help avoid costly delays or issues during installation.

Choosing a FAT: clear operational, compliance and risk-reduction benefits

Choosing a FAT gives tangible benefits:

Confidence in performance – Equipment is fully tested and verified prior to delivery.
Reduced risk of downtime – Potential problems are identified and resolved early.
Support for compliance – You receive documented evidence suitable for regulated environments.
Focus for your team – Your staff can concentrate on design, installation and ongoing operations.

Building stronger partnerships: testing as a collaborative quality process

FATs are more than a verification step; they reflect PBSC’s commitment to quality and client support. Each test helps improve processes, refine products and strengthen the trust our clients place in us.

Making FATs work for you: practical planning, clear communication and full support

We know testing can feel like an extra step. That is why we focus on making FATs straightforward to plan, well documented and aligned with your project timeline. Our team will work with you to schedule tests, define acceptance criteria and provide clear reporting so FATs add value and not delay.
