Frequently Asked Questions About Cleanroom Classifications

Frequently Asked Questions About Cleanroom Classifications

Cleanroom classification is one of the most confusing – yet important – parts of designing and building your cleanroom. If you’re installing a cleanroom for the first time, you’re bound to have a lot of questions. Here are some answers to the most common cleanroom classification questions we receive.

 

1. What classification do I need?

It depends on your industry. The requirements will vary depending upon what size particles need to be filtered, the sources of contamination present, and recommended air change rate. If your industry is government regulated, you can check applicable regulation to see what classification is required. If there is no government-mandated or industry default classification, you’ll need to determine the appropriate classification, based on your application.

 

2. How are cleanrooms classified?

There are two different classification scales that are generally used, the U.S. General Service Administration standards (FS209E) and International Standards Organization (ISO) classifications. The classes are determined by the maximum acceptable numbers of particles (by size) in the air per cubic meter. See Cleanroom Classifications & Standards here.

 

3. How often do I need to test my cleanroom to see if it’s meeting classification requirements?

ISO requires that air pressure difference and air flow be tested every 12 months for all classifications. Particle count tests must be performed every 12 months ISO Class 6 and above, every six months for ISO Class 5 and below. There are also tests recommended for all classes, every 24 months: installed filter leakage, containment filter leakage, recovery, and airflow visualization. These tests are regulated by ISO document 14644-2 Cleanroom Testing and Compliance.

 

4. How often do I need to have my cleanroom inspected?

This depends on your classification. The more stringent classifications will require more regular inspection. Inspection may coincide with compliance testing, which, depending upon the cleanroom classification may occur every six or 12 months.

 

5. How does cleanroom classification affect my budget?

Essentially, the more stringent the classification, the greater the cost. Strict classifications will require more air, energy, advanced technology, and equipment. See How Does Cleanroom Classification Affect Your Cleanroom Budget? for a more detailed breakdown of the costs.

Benefits of Modular Cleanrooms

Benefits of Modular Cleanrooms

If you have a cleanroom, are installing a cleanroom, or are considering whether your company needs a cleanroom, you already know why cleanrooms are important and necessary for your operations. You may not have considered, however, the type of cleanroom: a traditionally constructed space or a modular cleanroom. Modular cleanrooms have numerous benefits when compared to traditional construction, here are just a few:

 

Modular cleanrooms are free-standing

A free-standing cleanroom can be placed nearly anywhere, without extensive construction or renovation (and the costs and disruption those processes entail). If you have a free-standing modular cleanroom, you’re able to place it in the optimum location–whether that is the middle of a large open production floor or tucked back in a corner. You don’t need to build walls or change existing ones. Additionally, electricity and plumbing are already engineered into the cleanroom as part of the modular design.

 

Modular cleanrooms are quickly built

Building something from a kit, with the building materials included and the design already completed is always a simpler, easier, and quicker process than starting from scratch. Installing a modular cleanroom streamlines the building process–the design is complete, the materials selected and included, and construction simple and straightforward.

Just as modular cleanrooms are easy to assemble, they can also be easily disassembled, when compared to permanent construction. If you decide to move your cleanroom’s location within your facility or move it to a new facility, it can be quickly taken down and rebuilt in the new space.

 

Modular cleanrooms are easily modified or expanded

Should your company’s cleanroom needs ever change, modifying a modular cleanroom is much easier than renovating or remodeling a traditionally constructed space. Modular cleanroom walls are easily moved to accommodate a new cleanroom layout, and they can be expanded by adding additional wall pieces. You don’t need to start fresh with all new materials every time your cleanroom needs change.

A modular cleanroom can be a benefit for your company when you consider their flexibility, portability, and ease of installation and modification. Modular cleanrooms allow you to customize your cleanroom space to the ever-changing and evolving needs and capabilities of your company, and they are an excellent cleanroom solution that can save time and money.
