6 Test Method
6.1 Preparation
6.1.1 Make the pre-test preparation for the people, things and environment as per
the provisions of QC/T 573.
6.1.2 After the final inspection of the product, normal exit-factory state shall be
subject to.
6.1.3 The cleaning solution for cleaning shall be filtered as per the requirements of
QC/T 573.
6.1.4 The operation shall be maintained consistent during the cleaning process, so
that the results have higher repeatability and producibility.
6.2 Appearance cleaning
6.2.1 Before cleaning, all holes and tube joints shall be blocked.
6.2.2 Use clean cleaning solution to clean the product from the appearance.
6.2.3 The turbid liquid produced during the cleaning process shall not participate in
the evaluation of cleanliness.
6.3 Internal cleaning of the non-disassembled components
6.3.1 Inner-cavity, and sealed product components
6.3.2 The test products are automotive hydraulic power steering gear, steering oil
pump, steering power cylinder; use clean inlet tube to fill the product internal part with
clean cleaning solution from the container; under no-load condition, rotate by hand,
circulate for 10 times; collect the turbid liquid into clean container; wash with certain
amount of clean cleaning solution, shake the assembly, then collect the turbid liquid
together with that generated after the grinding.
6.3.3 The test products are steering oil tank, steering oil tube, joints; use clean inlet
tube to fill the 2/3 volume of product internal part with clean cleaning solution from the
container; then shake for 10 times in the front and back, left and right, up and down
directions; wash the products; collect the turbid liquid into the clean container; repeat
the operation for once; then collect the turbid liquid generated during the two
operations.
6.3.4 Use the clean oil return tube to return the turbid liquid to the container and
