Federal Register / Vol. 86, No. 209 / Tuesday, November 2, 2021 / Proposed Rules
For USBPD adaptive external power supplies, at the lowest nameplate output voltage, limit the contribution from each port to 10W when calculating the derating factor.
B If D 1, then loading every bus to its nameplate output current does not exceed the overall maximum output power for the power supply. In this case, load each output bus to the percentages of its nameplate output current listed in Table 4 of this section. However, if D <1, it is an indication that loading each bus to its nameplate output current will exceed the overall maximum output power for the power supply. In this case, at each loading condition, load each output bus to the appropriate percentage of its nameplate output current listed in Table 4 of this section, multiplied by the derating factor D.
v Minimum output current requirements.
Depending on their application, some multiple-voltage adaptive external power supplies may require a minimum output current for each output bus of the power supply for correct operation. In these cases, ensure that the load current for each output at Loading Condition 4 in Table 4 of this section is greater than the minimum output current requirement. Thus, if the test methods calculated load current for a given voltage bus is smaller than the minimum output current requirement, use the minimum output current to load the bus.
Record this load current in any test report.
vi Efficiency calculation. Calculate and record the efficiency at each loading point by dividing the UUTs measured active output power at that loading condition by the active AC input power measured at that loading condition.
A Calculate and record average efficiency of the UUT as the arithmetic mean of the efficiency values calculated at Loading Conditions 1, 2, 3, and 4 in Table 4 of this section.
B If, when tested, a UUT cannot sustain the output current at one or more of the loading conditions as specified in Table 4, the average active-mode efficiency is calculated as the average of the loading conditions for which it can sustain output.
C If the UUT can only sustain one output current at any of the output busses, test it at the loading condition that allows for the maximum output power on that bus i.e., the highest output current possible at the highest output voltage on that bus.
vii Power consumption calculation. The power consumption of Loading Condition 5
no-load is equal to the active AC input power at that loading condition.
2 Off-mode MeasurementIf the UUT
incorporates manual on-off switches, place the UUT in off-mode, and measure and record its power consumption at Loading Condition 5 in Table 4 of this section. The measurement of the off-mode energy consumption must conform to the requirements specified in section 6b1 of this appendix, except that all manual on-off switches must be placed in the off position for the off-mode measurement. The UUT is

considered stable if, over 5 minutes with samples taken at least once every second, the AC input power does not drift from the maximum value observed by more than 1%
or 50 milliwatts, whichever is greater.
Measure the off-mode power consumption of a multiple-voltage adaptive external power supply twiceonce at the highest nameplate output voltage and once at the lowest.

SMALL BUSINESS ADMINISTRATION
13 CFR Part 121
RIN 3245AH26

Small Business Size Standards:
Calculation of Number of Employees for All Programs and of Average Annual Receipts in the Business Loan, Disaster Loan, and Small Business Investment Company Programs U.S. Small Business Administration.
ACTION: Proposed rule.
AGENCY:

The U.S. Small Business Administration SBA or Agency is proposing to use a 24-month average to calculate a business concerns number of employees for eligibility purposes in all of SBAs programs. SBA also proposes to permit business concerns in its Business Loan, Disaster Loan, and Small Business Investment Company SBIC Programs to use a 5-year averaging period, in addition to the existing 3-year averaging period, for the purposes of calculating annual average receipts. These proposed changes will allow larger small businesses to retain their small business size status for longer, and some mid-sized businesses to regain small business status.
DATES: SBA must receive comments to this proposed rule on or before December 2, 2021.
ADDRESSES: Identify your comments by RIN 3245AH26 and submit them by one of the following methods: 1
Federal eRulemaking Portal: https
www.regulations.gov, follow the instructions for submitting comments;

Khem R. Sharma, Ph.D., Chief, Office of Size Standards, U.S. Small Business Administration, 409 Third Street SW, Mail Code 6530, Washington, DC 20416.
SBA will post all comments to this proposed rule on https
www.regulations.gov. If you wish to submit confidential business information CBI as defined in the User Notice at https www.regulations.gov, you must submit such information to Khem R. Sharma, Ph.D., Chief, Office of SUMMARY:

SUPPLEMENTARY INFORMATION:
I. Background Information This proposal seeks to implement two legislative enactments that affect how SBA calculates a business concerns size to determine whether the business qualifies as small for SBAs contracting, loan,1 and assistance programs. First, section 863 of the National Defense Authorization Act for Fiscal Year 2021, Public Law 116283 NDAA, changed the averaging period for SBAs employee-based size standards from 12
months to 24 months. Second, the Small Business Runway Extension Act of 2018, Public Law 115324 SBREA
amended section 3a2CiiII of the Small Business Act, 15 U.S.C.
632a2CiiII, to modify the requirements for proposed small business size standards prescribed by an agency without separate statutory authority to issue size standards.
A. Changes to Calculation of Number of Employees Section 863 of the NDAA amended two provisions of section 3a2 of the Small Business Act, which sets forth requirements for an agency that would prescribe a proposed size standard.
First, the NDAA provides that those requirements apply to the SBA when the agency acts pursuant to the authority in section 3a2A for SBA
to specify small business definitions or size standards. Second, the NDAA
amends section 3a2CiiI such that a proposed size standard for a manufacturing concern must provide for determining the size of the concern based on the employment during each of the concerns pay periods for the preceding 24 months. Previously, the statute specified the use of a 12-month period.
SBA proposes to implement the change to a 24-month period by amending 13 CFR 121.106. Section 121.106 currently provides that the size 1 These changes do not apply to the Paycheck Protection Program because the authority for that program expired on June 30, 2021.
