SAE J1598-2026 Laboratory Testing of Vehicle and Industrial Heat Exchangers for Durability Under Vibration-Induced Loading

This SAE Recommended Practice defines vibration-testing procedures for evaluating the durability of vehicle and industrial heat exchangers.

SAE J1598™ MAY2026 provides a laboratory test guideline for determining the durability of liquid-to-gas, liquid-to-liquid, gas-to-gas, and gas-to-liquid heat exchangers subjected to vibration-induced loading. The document covers facility and equipment requirements, test fixture design, integrity checks, installation, fixture frequency response, isolator selection and verification, vibration test modes, pressurization and heating, test execution, post-test inspection, and documentation. It supports durability comparison for heat exchangers used in vehicle and industrial cooling systems and references related SAE practices for thermal-cycle, pressure-cycle, and cleanliness and leakage testing.

Application Scope: Vehicle and industrial cooling systems, including radiators, charge air coolers, condensers, oil coolers, air dryers, and other liquid-to-gas, liquid-to-liquid, gas-to-gas, and gas-to-liquid heat exchangers.
