Yes, the same provisions apply to TP-901.

It is the tank with the highest ratio of surface area to tank volume in the fuel tank family.

No, the engine or equipment must simply be operated for 15 minutes prior to hot soak.

The canister should be positioned in a position comparable to where it would normally be found on equipment.

Yes, the engine with complete evaporative emission control system can be tested without the equipment chassis.

Manufacturers may only use a different test fuel if pre-approved by the Executive Officer as part of an alternative test procedure.

Yes, CARB will accept data generated with Indolene Clear as referenced in 40 CFR 1065.710(c).

Any alternative test procedure shall only be used if prior written approval is obtained from the CARB. In order to secure the CARB's approval of alternative test procedures, the applicant is responsible for demonstrating to the CARB's satisfaction that the alternative test procedures are equivalent to the required test procedures. Alternative test procedures may be submitted to the following address:

California Code of Regulations, title 13, section 2766(a) provides an exemption from the requirements of section 2755 for metal tanks, coextruded multilayer tanks, and structurally integrated nylon tanks on SORE equipment with engine displacement less than 80 cc. Section 2755 contains the permeation emissions performance standard for equipment that use engines with displacement less than or equal to 80 cc.

This exemption does not apply to any fuel tank for use on SORE equipment with engine displacement greater than 80 cc. Permeation emissions data or the Executive Order number of a certified fuel tank must be provided in certification applications for equipment using engines with displacement greater than 80 cc meeting the design standards of Cal.

Yes. When it comes to using two carbon canisters on a separate two tank system, CARB approves the use of one canister for each separate tank as long as the canister’s working capacity is compatible to the size of the tank.

However, when it comes to using multiple canisters in sequence for one large fuel tank, CARB would require that the canister manufacturer apply for a new component EO under the innovative products program. Canisters in sequence must be tested per TP-902 and the working capacity data should be submitted with the request for a new component EO. As with single carbon canister EOs, the working capacity of the canisters in sequence should determine the maximum fuel tank capacity.
