22、47-2:2006-12 6 4 Material Components in contact with the contents shall be made of food-safe stainless steel: e.g. steel of material No. 1.4301 cold rolled sheet conforming to DIN EN 10088-2 with smooth surfaces (surface finish 2B). 5 Design 5.1 General The types of containers used may differ, a typ
23、e being defined as one having the same design features. 5.2 Hygiene 5.2.1 The inner and outer surfaces of containers shall be designed so that they are easy to clean and soil can be easily removed, and so that liquids can drain completely, particularly in the zone of welds, radii and transitions. Te
24、sting shall be carried out in accordance with 7.6. 5.2.2 The inner surfaces of containers shall be designed in such a way that the contents are not adversely affected by the container. 5.2.3 The surface roughness Raof the inner surfaces of containers shall not exceed 1,6 m after the final treatment.
25、 6 Requirements 6.1 Constancy of volume 6.1.1 When tested in accordance with 7.3.1, the permanent increase in volume shall not exceed 0,10 % of the nominal volume. 6.1.2 When tested in accordance with 7.3.2, the permanent increase in volume shall not exceed 0,25 % of the nominal volume. 6.2 Dimensio
26、nal stability 6.2.1 After three drop tests, the inside diameters of the rims shall not have changed by more than 6 % of the original value. Cracking, chipping or peeling shall not occur, irrespective of the type. Testing shall be carried out in accordance with 7.4.1, 7.4.2 and 7.4.3. 6.2.2 There sha
27、ll be no permanent dimensional change when a vertical load is applied centrically to the socket. Testing shall be carried out in accordance with 7.4.4. 6.3 Safety against bursting 6.3.1 The design of containers shall be such that containers with no safety bursting point shall not burst at a proof pr
28、essure of at least 60 bar. Testing shall be carried out in accordance with 7.5.1. 6.3.2 Containers shall be provided with a safety bursting point. A maximum applied pressure of 45 bar shall be safely reduced by the rupture of the bursting point. While the pressure is being reduced, the container sha
29、ll not move position. Testing shall be carried out in accordance with 7.5.2. DIN 6647-2:2006-12 7 7 Testing 7.1 General Compliance with the requirements specified in clause 6 shall be verified in accordance with clause 7. Testing in accordance with this standard shall be carried out as type testing
30、using the container of the largest available size in each case. The test results shall be certified by an independent body in accordance with the requirements of this standard. 7.2 Procedure 7.2.1 Each of the tests described shall be carried out on containers which are completely filled with water,
31、the water temperature being the same during filling and testing. The requirements shall be deemed met if all three measurement results satisfy the requirements given in clause 6 (subject to the uncertainty of measurement specified in 7.2.2). If a container fails one of the tests, three other contain
32、ers shall be subjected to the same test. If one container fails again, the test shall be deemed not to have been passed. 7.2.2 Pressure gauges (manometers) of accuracy class 1,0 in accordance with DIN EN 562 shall be used for pressure measurement. For testing in accordance with 7.3, the measuring ra
33、nge of the instruments shall be 20 bar, for testing in accordance with 7.5 it shall be 100 bar. The maximum uncertainty of measurement shall be: 10 ml when determining the volume and 0,2 mm for length measurement. 7.2.3 The impact plate for testing in accordance with 7.4.1 and 7.4.2 shall be made of
34、 reinforced concrete with a cast-in and tied steel plate, which shall not be resilient (minimum thickness 25 mm, minimum weight 150 kg). 7.3 Constancy of volume 7.3.1 The containers shall be exposed to a test pressure of 9,1 bar for a period of 30 seconds at constant pressure. After relieving the pr
35、essure, the change in volume shall be determined. 7.3.2 The test pressure shall be increased to 13 bar and then be maintained at that value for 30 s. After having relieved the pressure, the change in volume shall be determined. 7.4 Dimensional stability 7.4.1 Three drop tests shall be carried out wi
36、th the container being filled to the lower edge of the socket, the container being dropped at an angle of 45 to the floor level from a height of 1,20 m, measured from the impact plate to the lower edge of the container, once with the top rim near the hand hole striking the impact plate and at least
37、once striking it with the top rim at the opposite hand hole. 7.4.2 Testing shall be repeated as described in 7.4.1, but with the container being dropped so that it strikes the impact plate with its top rim halfway between the hand holes. 7.4.3 Testing shall be repeated as described in 7.4.1, but wit
38、h the container being dropped so that it strikes the impact plate with its bottom rim. DIN 6647-2:2006-12 8 7.4.4 The container shall be stood on its bottom rim and a vertical force of 3 kN shall be exerted on the top of the container for 1 min. 7.5 Pressure test 7.5.1 For testing without a safety b
39、ursting point, the container shall be completely filled with water and the internal pressure shall be increased steadily over a period of two to four minutes until a value of at least 60 bar is achieved. 7.5.2 For testing with a safety bursting point, the container shall be completely filled with wa
40、ter and the internal pressure shall be increased steadily over a period of two to four minutes until a value of 45 bar is achieved. 7.6 Hygiene Compliance with the requirements specified in 5.2 shall be verified by checking the geometric design of the container (see DIN 10502-1, DIN 10502-2 and DIN
41、EN 1672-2). The surface roughness, the smallest radii and the draining characteristics shall be checked as part of type testing in accordance with 5.2.3. 8 Marking Containers type tested in accordance with this standard shall be durably marked as follows: a) manufacturer or manufacturers trademark;
42、b) year of manufacture; c) serial number; d) allowable operating pressure.
