These Procedural Standards were developed using reliable engineering principles andresearch plus consultation with, and information obtained from, manufacturers, users,testing laboratories and others having specialized experience. They are subject torevision as further experience and investigation may show is necessary or desirable.Cleanroom Performance Testing, which complies with these Procedural Standards, willnot necessarily be acceptable, if when examined and tested, it is found to have otherfeatures that impair the result intended by these standards. The National EnvironmentalBalancing Bureau assumes no responsibility and has no liability for the application of theprinciples or techniques contained in these Procedural Standards. Authoritiesconsidering adoption of these Procedural Standards should review all Federal, State, localand contract regulations applicable to the specific installation.

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

Todays buildings provide highly controlled indoor environments. This is especially true when dealingwith clean environmental conditions required by todays micro-electronics, bio-medical, and otherhighly technical industries. These conditions could not exist without sophisticated mechanicalsystems created by a team of skilled professionals. A key member of this team is the NEBB CertifiedCleanroom (CPT) Firm.

This Third Edition represents a departure from past editions and is divided into two distinct Parts:Standardsand Procedures. These CPT procedural standards have been developed using languagedefined by Shall, Should, and May as it relates to the standards and procedures described in thismanual. It is important to note these particular words throughout this manual and how they pertain tothe NEBB standards and procedures.

These standards and procedures are intended as the minimum NEBB requirements that a NEBBCertified CPT Firm shall follow when performing Cleanroom Testing and Certification procedures.Contract documents may supercede the NEBB requirements. These CPT Procedural Standards havebeen carefully compiled and reviewed by the NEBB Technical Committees.

Part 1 STANDARDSPart 1, STANDARDS, covers the requirements for Quality Control and Compliance, InstrumentationRequirements, and CPT Reports. Revised requirements for CPT instruments and reports areidentified. The new report requirements allow the NEBB Certified Firm more flexibility in designingtheir reports by prescribing sets of information that "Shall, Should and/or May" be required tocomplete a CR Report.

Part 2 PROCEDURESPart 2, PROCEDURES, covers measurement procedures of the various testing requirements forcleanroom testing and certification.

APPENDICESThe Appendices include a suggested CPT Specification, References, and Engineering Formulas.

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

SECTION 2 NEBB PROGRAM,

QUALITY CONTROL AND

COMPLIANCE

2.1 NEBB PROGRAMS

The National Environmental Balancing Bureau (NEBB) is a not-for-profit organization founded in 1971to:

a) develop standards, procedures and programs for the performance of testing, balancing andcommissioning of building systems,

b) promote advancement of the industry through technical training and development,c) operate programs to certify firms and qualify individuals who meet and maintain NEBB

standards with integrity.

Additional information on NEBB Programs is available at www.nebb.org.

2.1.1 NEBB DISCIPLINES

NEBB establishes and maintains standards, procedures, and specifications for work in its variousdisciplines, which include:

a) Cleanroom Performance Testing (CPT)b) Testing-Adjusting-Balancing (TAB) -- Air and Hydronic Systemsc) Sound and Vibration (S&V) Measurementd) Building Systems Commissioning (BSC)

e) Retro-Commissioning (Retro-Cx)f) Fume Hood Testing (FHT)

Each discipline is anchored by a NEBB Procedural Standards manual that provides guidelines forwork to be performed. NEBB also has created technical manuals, training materials and programs,and seminars to enhance and support each discipline.

2.1.2 FIRM CERTIFICATION

NEBB certifies firms that meet certain criteria, ensuring strict conformance to its high standards andprocedures. Among other requirements, NEBB Certified Firms must document a record ofresponsible performance, own a complete set of instruments required for the sophisticated techniquesand procedures necessary to perform cleanroom certification tests and have a NEBB Qualified

Supervisor as a full-time employee.

2.1.3 SUPERVISOR QUALIFICATION

NEBB also establishes professional qualifications for the supervision and performance of work in itsvarious disciplines. NEBB Qualified Supervisors must have extensive experience, and they mustpass appropriate, college-level written examinations and demonstrate certain practical workingknowledge and proficiency in the use of instruments required for the various disciplines.

2.1.4 TECHNICIAN QUALIFICATIONNEBB also qualifies technicians who must possess certain background and experience as well aspass rigorous written and practical examinations. For example, NEBB Qualified CPT Technicianstatus is maintained by continued employment with a NEBB Certified CPT Firm, and the Technicianmust perform a minimum number of hours of CPT work each year.

2.1.5 RECERTIFICATION REQUIREMENTS

Through the recertification procedures, the firm must verify that its NEBB Qualified Supervisor is stillon staff and that it continues to own a complete set of instruments that are in current calibration. Inaddition, the firm's NEBB Qualified Supervisor renews his or her qualification. Among otherrequirements, Supervisors must keep abreast of developments in their discipline by attending andsuccessfully completing continuing education seminars annually.

2.2 QUALITY ASSURANCE PROGRAM - CONFORMANCE CERTIFICATION

The CPT credibility of NEBB is built by maintaining integrity through high standards, quality programs,

and demonstrated capabilities of its certified firms. As further assurance, NEBB offers a QualityAssurance Program to guarantee that the work will be accomplished in accordance with its standards.The NEBB Certificate of Conformance Certification is an integral element of the program. It assuresthat the NEBB Certified Firm will perform specified services in conformity with the current applicableNEBB Procedural Standards.

2.2.1 PROGRAM ADVANTAGES

The NEBB Quality Assurance Program affords building owners, architects, engineers and otheragents a reliable basis for specifying work within the various disciplines of NEBB. The programpromotes proper execution of projects by ensuring compliance with NEBB standards and procedures.

2.2.2 NEBB QUALITY ASSURANCE PROGRAM CERTIFICATEThe NEBB Quality Assurance Program Conformance Certification is available for any project. Ifspecified in the contract documents, the NEBB Certified CPT Firm shall make application to the NEBBOffice for a Certificate of Conformance Certification

2.3 QUALITY CONTROL AND COMPLIANCE

Building owners are entitled to a professional service by every NEBB Certified Firm on every project,whether the job is NEBB-specified or not. It is the responsibility of the NEBB Certified Firm and itsNEBB Qualified Supervisor to establish and maintain procedures and practices that will assure aconsistent pattern of high quality work on all projects. This point cannot be overemphasized.

2.3.1 CPT WORK COMPLIANCE

The scope of work shall be performed as specified in the contract documents, or as agreed tobetween the Owner/Buyer and the NEBB Certified CPT Firm. Each relevant or applicable item asidentified in the contract documents by description, or by reference, shall be performed and recordedin the report. Data presented in a report shall provide an accurate quantitative record of systemmeasurements and information.

References to desired procedures may include statements such as "the work will be performed inaccordance to NEBB Standards." When specifications indicate that the work shall be performed in

PART 2 - PROCEDURES

SECTION 6 CLEANROOMSAFETY

6.1 INTRODUCTION

A health and safety program is a definite plan of action designed to prevent accidents andoccupational diseases. A health and safety program should include the elements required by thehealth and safety legislation as a minimum. This document summarizes the general elements of ahealth and safety program. This should help NEBB organizations to develop programs to deal withtheir specific needs. Because many small and medium-sized enterprises lack the resources of larger

organizations, it is even more vital that small and medium-sized enterprises involve all employees inhealth and safety activities. The more comprehensive the program is, the more employeeinvolvement can be expected.

The health and safety program discussed in this section is a guideline. The project specific safetyprogram shall be as specified in the contract documents or as agreed to between the Owner/Buyer andthe NEBB Certified CPT Firm.

Most often the NEBB Certified CPT firm will be required to follow the client project specific safetyprogram, however in the absence of this project specific safety program, the firms SOP for cleanroomhealth and safety program shall be followed.

6.2 DESIGNING A HEALTH AND SAFETY PROGRAM

6.2.1 DESIGNING A PROGRAM POLICY

A NEBB organization's health and safety policy is a statement of principles and general rules thatserve as guides for action.

6.2.1.1 The policy should mention:a. Management's commitment to protect the safety and health of employeesb. The objectives of the programc. The organization's basic health and safety philosophyd. Who is accountable for health and safety programse. The general responsibilities of all employees

f. That health and safety shall not be sacrificed for expediencyg. That unacceptable performance of health and safety conduct will not be tolerated

6.2.1.2 The policy should be:a. Stated in clear, unambiguous, and unequivocal termsb. Signed by the incumbent chief executive officerc. Kept up-to-dated. Communicated to each employeee. Adhered to in all work activities

6.2.2 DESIGNING A TRAINING PROGRAM

The objective of training is to ease the implementation of health and safety policies into specific jobpractices and to raise awareness and skill levels of a technician to an acceptable standard.

6.2.2.1 Occasions when employee training should be required are:

a. Commencement of employmentb. Reassignment or transfer to a new jobc. Introduction of new equipment, processes, or proceduresd. Inadequate performancee. Customer and job site related chemical or biological hazards, equipment, processes, or

procedures.

6.2.2.2 The NEBB Certified CPT Firm should have the following topics included in the safety training:a. Safety and the supervisorb. Know your accident problemsc. Human relationsd. Maintaining interest in safety

e. Instructing for safetyf. Industrial hygieneg. Personal protective equipmenth. Industrial housekeepingi. Material handling and storage

j. Guarding machines and mechanismsk. Hand and portable power toolsl. Fire protection
