5.1 The formula should be purified under the surgical anti-people will be ten and other products: 5-2 with detailed difficult mail: the test should be small and small in the clamping, fixed, the sample is too small light method light holding, solid Zong, forget to use the pull method to weld the wire in the test 1. The sample is too large and should be based on the policy of folding, creating the method before teaching. 5.3 The selection of the whole surface of the steam: according to the rice product bottom delivery take the milk surface rod and the silk product Kun should be replaced by the joint control. The test should be transported from the edge of the money, the tip has, the hole is drawn, the explosion level, the mark is good, the flat part price, the Fangyuan is selected and the seat is smooth. 5.4 The coating of the test fence: the surface of the test fence shall be washed with 10% clean water and 10% lacquer. The test fence shall be sealed or embedded with resin. The test fence shall be small. The coating surface shall not have any holes. Test conditions and steps: 5. Test conditions: 6..1 Liquid drop: 4.

Ground and twenty water out: the telegram according to the electricity 6.2.3 will work electricity: reduce) reference electricity to receive the sincerity of the part of the test solution, the absolute product should be tested on the training should also be tested molten and 1 with soil, reference to the same light Lu Jinbai pipe fire end part of the test center 1 art 6.2.4 inspection only the actual book requirements of the device to connect the wires will be receiver ratio, according to the trade in the air, input the required parameters (select constant position control, let record Eg Jin report curve)
5.2.5 effective mutual n, record the natural erosion [position from the self-warming off speed of the factory storage, with V/min heart learning to scan the speed stop time description micro-adjustment of the electricity should be light until the current rate m1 time network verification
5.2.5 after the end of these tests, the cloud is absolute, with an estimated Use a microscope to check whether there is corrosion and missing holes. 5.2 Each station shall test the test results of the test agent or sample and the test liquid. 7-Chemical line 7.2 Point of gradual determination: When the chemical line of the purification area 1 point rises sharply: This point shall be the point of creation of the product () 7.3 All batches of products shall be The half-line training is a style 3 work, in which the special small is used, and the third use of the decimal product is to be used. B test report

2 , also the conditions of the chemical measurement system (test rate, test product, test machine, only chemical measurement system), name of reference epidemic, natural code, impulse median, pitting median, calibration curve, B.1.4 Name of detection and acceptance personnel, etc. YY, T\074—2062 [Normative Appendix; Supplementary information] 4.1 This standard applies to the manual step-by-step method for exciting products. The rate of change of potential is mV/mr or the rate of change of potential is 2n/year. The position and flow rate of the test are as follows: A.2 When the position of pitting corrosion cannot be determined, check whether the product has caused seam corrosion or whether it has caused continuous tunneling corrosion. The overpotential should be abandoned and the test should be re-accepted.
A.3 The point-inverse electrochemical instrument measured in this standard reflects the material and process level of the tested product and can replace the detection of surface defects of the test station. Electrochemical equipment:
