R134a Refrigerant Automotive Air-Conditioned Hose
- Ground Vehicle Standard
- J2064_200512
- Revised
Scope
Rationale
-
Moved Table 1 from section 3.2.4 to section 5.2.4 - (Table applies to this section).
-
Renamed section 5.1 from Test Conditions to Sample Conditioning (samples are being conditioned).
-
Clarified Section 5.1. The temperature of the testing room shall be maintained at 23 °C ± 2 °C. The temperature of the test hose or hose assemblies shall be stabilized for 24 h at the testing room temperature prior to testing. Charged Samples shall be stabilized for 24 hrs. @ 23 °C ± 2 °C prior to testing. Samples shall be checked to ensure specified charge and identify charge loss.
-
Section 5.2.2 Charging Procedure and Initial Weights - add evacuation to the test procedure. (is currently a common practice)
-
Section 5.2.4 Establish Constant Loss Rate - replaced exposures with exposure (corrected grammar)
-
Section 5.2.4 Establish Constant Loss Rate - replaced taken with reported (corrected grammar)
-
Section 5.2.4 Establish Constant Loss Rate - Deleted This is not to be a lot release test. The lot release test is to be agreed upon between the vendor and consumer. (redundant)
-
Section 5.2.5 Loss Rate Determination - Deleted section title 5.2.6 and added the exact wording for the acceptance determination under Section 5.2.5 (corrected mislabeled section numbering).
-
Section 5.3 Coupling Integrity - Deleted Either Test Option 1 or Test Option 2 may be used. (redundant).
-
Section 5.3 Coupling Integrity - Deleted Each assembly is attached to a canister having an internal volume of 1260 cm3 ± 25 cm3 and equipped with a charging fitting. Replaced with Each assembly is attached to a canister with a minimum internal volume of 900 cm3 and equipped with a charging fitting. The minimum canister volume ensures a maximum pressure loss of 0.10 MPa between recharges. A seventh coupled assembly is used as a volatility sample to account for weight losses not associated with refrigerant losses.

Issuing Committee
Interior Climate Control Steering Committee
The SAE Interior Climate Control Standards Committee consists of a Steering Committee plus the following sub-committees: Fluids, MAC Supplier, Service, and Vehicle OEM. The SAE Interior Climate Control Standards Committee has published more than 50 documents and has an HS-2900 handbook. These documents include standards on safety, refrigerants, components, testing, service procedures, service equipment, and training. Many of these standards are cited in EPA regulations. SAE ICCC membership includes engineers from every global automaker, system and component supplier, and service equipment manufacturer many of which are considered to be experts in Automotive Climate Systems.
