Procedural Standard for Building Enclosure Testing SECOND EDITION – 2015   The purpose of the NEBB Procedural Standards for Building Enclosure Testing is to establish a uniform and systematic set of criteria for the testing and commissioning of building enclosure systems. This publication is the second edition of the BET Procedural Standard. Similar to the other NEBB disciplines, the Procedural Standard serves as the anchor for the program. There are several standards that define building enclosure testing such as ASTM E779 Air Leakage Testing and ASTM E1827 Building Airtightness.   Additionally ASTM E 1186 defines the Standard for thermography. These publications define the testing procedures to be used when performing BET and are well recognized and respected in this area of expertise. The NEBB discipline builds on these standards and complements them by providing a program combining the testing requirements with a complete package for firm and professional certification. The NEBB Procedural Standard and the NEBB Building Enclosure Testing (BET) program define the requirements for certification of the firm, for certification of the professional, for educational and experience requirements, for reporting consistencies, and for instrumentation requirements. This Procedural Standard is similar to other NEBB Procedural Standards in that it is divided into two distinct Parts: Standard and Procedures.   This Procedural Standard is intended to be the minimum NEBB requirement a NEBB BET Certified Firm. When performing testing of building enclosure systems and reporting the results contract documents may supersede the NEBB requirements. This BET Procedural Standard has been carefully compiled and reviewed by the NEBB Technical Committees.     The NEBB Procedural Standards and the NEBB Building Enclosure Testing (BET) program define the requirements for certification of the firm, for certification of the professional, for educational and experience requirements, for reporting consistencies, and for instrumentation requirements.   This Procedural Standards is similar to other NEBB Procedural Standards in that it is divided into two distinct Parts: Standards and Procedures. These standards and procedures are intended as the minimum NEBB requirements a NEBB BET Certified Firm follows when performing testing of building enclosure systems and reporting the results. Contract documents may supersede the NEBB requirements. These BET Procedural Standards have been carefully compiled and reviewed by the NEBB Technical Committees.   Part 1. STANDARDS Part 1, STANDARD, covers the requirements for Quality Control and Compliance, Responsibilities, Instrumen-tation Requirements and BET Reports. The report requirements allow the NEBB Certified Firm more flexibility in designing reports by prescribing sets of information required to complete a BET Report.   Part 2. PROCEDURES Part 2, PROCEDURES, covers required Safety Requirements and an Overview of Testing Requirements to be followed when using this Procedural Standard.   Part 3. APPENDICES The APPENDICES are normative and informative. They include a suggested NEBB BET specification, sample calculations, illustrations, references, engineering formulas, definitions, and instruments. This edition of the BET Procedural Standard, when used by a NEBB BET Certified Firm, assures the building own-er of standard accurate reporting of Building Enclosure Testing.
