Introduction
This test method covers a laboratory screening procedure for
evaluating the effectiveness of engine coolants in combating
corrosion of aluminum casting alloys under heat-transfer conditions
that may be present in aluminum cylinder head engines.
Characteristic
1. The ASTM D4340 Corrosion Analyzer consists of a support and one
or two thermal corrosion cell, with a working pressure of 40 psi
and a working temperature up to 160℃.Electronic timer controls
testing time, and electronic temperature controller controls
temperature;
2. The instrument casing is made of ceramic coated refined steel
surface, which is durable;
3. There is a protective cover outside the corrosion cell;
4. The thermal corrosion cell is made of heat-resistant glass,the
cover and bottom are made of stainless steel material;
5. The stainless steel heat conducting rod is controlled by a 950W
heater which is regulated by a Solid-state relay;
6. The components installed on the top of the corrosion cell, such
as the vent valve, pressure reducing valve, and pressure gauge, are
all made of stainless steel material;
7. The injection port is covered with a sealing cap, and four
stainless steel columns are connected to the upper cover and base;
8. The temperature controller of the instrument is an intelligent
regulator that integrates temperature control and display, and is
equipped with a microprocessor for PID adjustment. The sensor is a
K-type thermocouple;
9.For dual position instruments, all components have two sets;
10. The ASTM D4340 Corrosion Analyzer has over temperature safety
protection function;
11. Electronic timer can preset testing time. Upon reaching the
time, the instrument will automatically stop heating, and the two
corrosion pools can be tested separately without interfering with
each other;
