What is NEBB? The process of validating cleanrooms according to NEBB standards.

Testing and validating cleanrooms is a necessary activity for any factory or manufacturing unit that has constructed and installed cleanrooms. Its purpose is to detect potential issues early, prevent unwanted incidents, and ensure that critical factors in the cleanroom such as temperature, humidity, pressure, cleanliness, etc., always meet standards.

Process of validating cleanrooms according to NEBB standards

Validating cleanrooms according to NEBB Certification is typically carried out in three main stages:

Stage 1: Installation Validation
Cleanroom validation according to NEBB Certification is performed to check connections before equipment, manufacturing materials, and workers are present. Demonstrate that installations are accurate.

Stage 2: Operational Validation
Conducted after equipment installation but before workers perform tasks inside the cleanroom. This test in cleanroom certification according to NEBB Certification ensures the operational performance of equipment as per the original design.

Stage 3: Performance Validation.
The test is conducted and evaluated when all equipment is operational and workers are directly working. Cleanroom validation according to NEBB Certification at this stage demonstrates that the cleanroom’s performance meets the organization’s intended purpose.

After initially receiving NEBB certification for cleanroom validation, manufacturing facilities still need to regularly inspect and evaluate cleanrooms. Typically, NEBB certification for cleanroom certification has a specific validity period. Therefore, companies need to have a periodic validation plan to extend the life and improve the efficiency of cleanrooms.
