10 These buildings include very sophisticated mechanical systems created by a team of skilled professionals. A key member of this team is the NEBB Certified Testing, Adjusting and Balancing (TAB) Firm (CF).This eighth edition represents an update from past editions but remains divided into two distinct parts: stan-dards, and procedures. This Procedural Standard has been developed using language defined by Required (Min-imum Requirements) as it relates to the standards and procedures described in this Standard and these procedures are intended as the minimum NEBB requirements that a CF must follow when performing TAB procedures.
