The purpose of the NEBB Procedural Standards for Certified Testing of Cleanrooms is to establish a uniform and systematic set of criteria for the performance of the cleanroom testing and certification.

This Third Edition represents a departure from past editions and is divided into two distinct Parts: Standards and Procedures. These CPT procedural standards have been developed using language defined by "Shall, Should, and May" as it relates to the standards and procedures described in this manual. It is important to note these particular words throughout this manual and how they pertain to the NEBB standards and procedures. These standards and procedures are intended as the minimum NEBB requirements that a NEBB Certified CPT Firm shall follow when performing Cleanroom Testing and Certification procedures. Contract documents may supercede the NEBB requirements. These CPT Procedural Standards have been carefully compiled and reviewed by the NEBB Technical Committees.

This Third Edition of the CPT Procedural Standards, when used by NEBB Certified CPT Firms, will assure the building owner or operator that facility systems have been properly tested within design and installation limitations.
