Which two references provide the criteria for lighting minimums?

• A. NFPA 70 and ANSI RP-7
• B. IENSA lighting handbook 9th edition and ANSI RP-7
• C. IEC 60598 and ISO 8995
• D. IEEE 1584 and EN 12464

Answer: (B)

Lighting minimums are established by authoritative design references that describe how bright a space should be for different tasks and environments. The most appropriate pair here is the IESNA Lighting Handbook (9th edition) together with ANSI RP-7. The IESNA Handbook is the primary source that provides recommended illuminance levels, glare control guidance, and criteria for evaluating lighting quality across a wide range of tasks. ANSI RP-7 offers practical guidance specifically for industrial and maintenance settings, outlining minimum illumination levels and layout considerations for typical industrial work, which directly informs what constitutes acceptable lighting in those environments.

The other options don’t provide this exact pairing of criteria for lighting minimums: NFPA 70 is the electrical safety code, not a lighting performance standard; IEC 60598 covers luminaire safety and performance, ISO 8995 and EN 12464 are international/European guides to indoor workplace lighting but aren’t the standard pairing used in many AMTC contexts; IEEE 1584 focuses on arc-flash hazard calculations.
