AUTOMOTIVE AIR CONDITIONING HOSE

1988-07-01
HISTORICAL
J51_198807
This specification covers reinforced rubber and reinforced thermoplastic hose, or hose assemblies, intended for conducting liquid and gaseous dichlorodifluoromethane (refrigerant 12) in automotive air conditioning systems. The hose shall be designed to minimize permeation of refrigerant 12 and contamination of the system and to be serviceable over a temperature range of -30 to 120°C (-22 to 248°F). Specific construction details are to be agreed upon between user and supplier.

CLAMPING FORCE TEST PROCEDURE

HISTORICAL
J2371_199708
This SAE Recommended Practice is a test procedure to obtain force data for self-compensating type clamps (SAE Type E, CTB, and CTW).

COMPRESSION SET OF HOSES OR SOLID DISCS

1993-05-01
HISTORICAL
J1638_199305
This SAE Recommended Practice is used for establishing the compression set that could be expected to occur with engine coolant hoses under securing clamps. It seeks to reproduce the type of indentation caused by the clamps in the wall of the hose. An excessive compression set measured by this method would indicate a hose that could eventually allow leakage of coolant past the clamps in service. This method has been found to give repeatable results in the range of 25% to 50% initial compression.

COOLANT SYSTEM HOSES

1974-01-01
HISTORICAL
J20E_197401
This type of hose is primarily for severe, critical, and heavy-duty service of which the diesel-locomotive application is a typical example. The hose is intended to withstand the effects of pressure systems, various present types of coolants, cold temperatures down to −40°F (−40°C), and unskilled application to connections not particularly designed for ease of assembly with the hose. When desired, hose with one class of material in the tube and another in the cover may be obtained. In such cases, the physical properties specified for respective parts shall apply. Adhesion requirements shall be based on the class of material for which the lower value is specified.

HISTORICAL
J20_198606
This standard covers reinforced and flexible hoses intended for use in water and ethylene glycol based engine collant system application. Compounds based on different synthetic rubber grades are specified and designated Class A, high temperature resistant; Class B, high oil swell resistant; Class C, medium oil swell resistant; Class D-1, low oil resistant, improved service; Class D-2 low oil resistant, standard service; Class D-3, low oil resistant, high temperature resistant, premium service; Class E, low oil resistant, fiber elastomer composite. Typical physical characteristics for each type hose are shown in Table 1.

J1638_200411
This SAE Recommended Practice is used for establishing the compression set that could be expected to occur with a thermoset elastomeric hose under securing clamps. It seeks to reproduce the type of indentation caused by the clamps in the wall of a hose. An excessive compression set measured by this method may indicate a hose that could eventually allow leakage of fluid or gas past the clamps in service.
