NORMATIVE APPENDIX E—
IAQ LIMIT REQUIREMENTS FOR
OFFICE FURNITURE SYSTEMS AND SEATING


  • (This is a normative appendix and is part of this standard.)

    E1. IAQ LIMIT REQUIREMENTS

    Installed office furniture system workstations and seating units shall comply with both the requirements of Sections E1.1 and E1.2.

    E1.1
    At least 95% of the total number of installed office furniture system workstations and at least 95% of the total number of seating units installed shall comply with either of the following criteria at 168 hours:

    a. Emissions concentration limits as shown in Table E1.1 and defined in Section 4.2.1 of ANSI/BIFMA X7.1

    b. Emission factors as shown in Table E1.2 and defined in Section 7.6.1 of BIFMA e3.

    TABLE E1.1 Workstation Systems and Seating Office Emissions Concentration Limits

    Chemical ContaminantWorkstation Emission LimitsSeating Emission Limits
    TVOCtoluene≤0.5 mg/m3≤0.25 mg/m3
    Formaldehyde≤50 ppb≤25 ppb
    Total aldehydes≤100 ppb≤50 ppb
    4-Phenylcyclohexene≤0.0065 mg/m3≤0.00325 mg/m3

    E1.2
    At least 50% of the total number of installed office furniture system workstations and at least 50% of the total number of seating units installed shall not exceed the individual volatile organic chemical (VOC) concentration limits listed in Table E1.3 at 336 hours (14 days) or sooner when determined in accordance with the ANSI/BIFMA M7.1.

    When the emission factor at 336 hours is determined using the power-law defined in ANSI/BIFMA M7.1 (Sections 10.4 and 10.5), emission factors with –0.20 < b < 0.20 shall be reported as constant.

    Small chamber testing of component pieces of workstations per the ANSI/BIFMA M7.1 shall be allowed, provided that there is third-party oversight in selecting representative components and in applying the calculations in ANSI/BIFMA M7.1 to estimate the emission factor of a product.
