Choose three different positions for each sample for testing. Take three samples for testing. When all three samples are conforming, this item is conforming. 5.2.1.3 Ink adhesion of printing pattern For reused products or components, the ink adhesion of printing pattern The hardness is HRC 45~50. Figure 5 – Sharp needle 5.2.1.7.2 Pull resistance Use a suitable fixture, along the axis of the sample, to respectively and securely clamp both ends of the sample. Along the axis direction of the sample, apply a pulling force of (5±2) N. Check the sample. Then, in the same direction, at a speed of (200±10) mm/min, increase the pulling force to (90±5) N. Maintain (10±0.5) s. Visually inspect the sample. During the test, the fixture shall clamp the sample without damage. Avoid damage to the place where the sample is clamped and affect the test result. If it happens, the test result shall be invalid. 5.2.2 Test method for system performance 5.2.2.1 Fitting of components of feeding bottle Assemble samples according to the instructions for use. Check if it can be assembled correctly. 5.2.2.2 Resistance to boiling water Under normal temperature and pressure, disassemble the sample.

Figure 6 -- Test template A and test template B 5.2.2.6.2 Other requirements for teat or drinking accessory 5.2.2.6.2.1 Length Use a measuring tool of which the precision is 0.02mm to measure the length from the top of the sample to the locking ring. If there is no locking ring, measure the length from the top of the sample to the mouth of the container. See Figure 8. 5.2.2.6.2.2 Safety retention The purpose of the safety retention test is to detect the safety of the components of the feeding bottle (including teat or drinking accessory) during normal use. Because the feeding bottle is made up of multiple components, the components of the feeding bottle (including teat or drinking accessory) shall be assembled according to the instructions for safety retention test. Assemble the sample correctly according to the instructions for use. Use a torque of (1.75±0.25) N·m to install the locking ring. As shown in Figure 7, fix the sample. The axis of the container of the sample shall be at a 45° angle to the main axis. Choose a right fixture to clamp the position where the test component is (10±2) mm away from the top. Apply a tension of (5±2) N at an angle of 45° to the axis of the sample. Check the sample. Then in the same direction, at a speed of (200±5) mm/min, increase the pulling force to (60±5) N. Maintain (10±0.5) s. Visually inspect the sample. A in Figure 7 is the direction to apply force. When testing, the fixture shall clamp the sample without damage. Avoid damage to the position where the sample is clamped and affect the test result. If it happens, the test result shall be invalid. 5.3.2.1.1 Soda lime glass Test according to the method specified in GB/T 4547. 5.3.2.1.2 Borosilicate glass Test according to the method specified in GB/T 6579. 5.3.2.2 Resistance to water Test according to the method specified in GB/T 6582. 5.3.2.3 Internal stress Test according to the method specified in GB/T 4545. 5.3.2.4 Mechanical shock strength Test according to the method specified in GB/T 6552. 6 Inspection rules 6.1 Classification of inspection The product inspection is divided into exit-factory inspection and type inspection. 6.2 Exit-factory inspection 6.2.1 Batching The products not exceeding 50,000 in quantity, with the same raw materials, specifications, formulas, and processes, are a batch.
