1. Introduction

Air conditioner hose burst test stand is a verification for the test of boosting, holding pressure, depressurizing, bursting, etc. in the liquid-filled environment for an automotive pipeline (Air Conditioning System).

2. Test items

QC/T 664-2000 Air conditioner (HFC-134a) hose and hose assemblies 5.11 Burst pressure test 

3. Technical parameters

Test pressure: 0-20MPa/30MPa

Test medium: Water or oil

Test items: 1. Burst test: direct burst 2. Holding pressure burst test: boost-holding pressure-burst, pressure, holding time arbitrarily set 3. Multi-step holding pressure test: boost → holding pressure → boost → Holding pressure → boost → holding pressure → boost → holding pressure → boost → holding pressure → burst 5th step boost, holding pressure, time can be set, number of steps can be selected; 4. Fatigue test: boost → holding pressure → pressure relief, can be cycled.
