Current through Register 2024 Notice Reg. No. 50, December 13, 2024

Section 2755 - Permeation Emission Standards

On or after the model year set out herein, and through model year 2023, fuel tanks and fuel lines used on equipment subject to this section must not exceed the following permeation rates:

Permeation Emission Standards

(grams per meter² per day)

Effective Date Model Year	Applicability	Requirement ¹
2007	Small off-road engines with displacements <= 80 cc	Fuel tank permeation emissions shall not exceed 2.0 grams per square meter of internal surface area per day as determined by TP-901.
2020	Small off-road engines with displacements <= 80 cc	Fuel lines shall meet the requirements of section 2754(b)(2), except that the permeation emission standard for fuel lines used on chainsaws is 225 g·m^-2·day^-1.

1 Permeation rate must be measured to two significant digits.

(a) Data documenting the permeation rate of fuel tanks and fuel lines must be included in a certification application.

(b) The test procedure for determining compliance with the fuel tank permeation emission standard is TP-901, which is incorporated by reference herein and specified in section 2758. The test procedure used to determine compliance with the fuel line permeation emission standard is SAE J1737, SAE J30, SAE J1527, or, only for fuel lines with inner diameter 4.75 mm or less, SAE J2996.

(c) Engines that certify to the diurnal emission standards set forth in section 2754 of this Article do not need to meet the requirements of this section.
