Amendment / Modification

This document, FAA-STD-019f, Change 2, dated August 23, 2019, details several modifications to the standard for lightning and surge protection, grounding, bonding, and shielding requirements for facilities and electronic equipment.

Key changes include:

• Typo Correction: A typo in section 4.5.2(d) has been corrected.
• SPD Ground Conductor Sizing: Section 4.6.2.3(a) has been updated to provide guidance on sizing the SPD ground conductor in small panels where the GEC size is smaller than the manufacturer's maximum allowed conductor size.
• Grounding of Separately Derived Systems: Sections 5.2.4(b) and (c) have been updated for clarity regarding the grounding of separately derived systems in ATCT environments.
• Figure Updates: Figure 19 has been updated for clarity. Figure 3 has been updated to remove a specific reference to exothermic weld type, aligning with a policy change.
• Exothermic Weld Policy: Section 4.2.3.1 has been updated to permit irreversible compression type bonding connections (UL 467 and UL 96 listed) in lightning protection system applications, particularly in staffed operational facilities where exothermic welds might be hazardous. This change affects sections 4.2.3.1, 4.2.3.2, 4.3.5.1, 4.3.7.2, and 4.7.3.3.
• Ground Cable Color Coding: Table 5 has been updated to include color coding for ground cables connecting the main and supplemental ground plates to the Earth Electrode System (EES).

Sections 4.5.2(d), 4.6.2.3(a), 5.2.4(b), 5.2.4(c), Figure 19, Figure 3, 4.2.3.1, 4.2.3.2, 4.3.5.1, 4.7.3.3, and Table 5 have been affected by these changes.

This amendment primarily updates technical specifications and policies related to grounding, bonding, and surge protection. It does not appear to introduce changes to proposal submission deadlines or evaluation factors, but bidders should review the updated technical requirements carefully.
