31、(see e.g. Figure 1) and smoothly finished. They shall be symmetrical about the axis which shall be perpendicular to the plane of the base. DIN EN ISO 13132:2011-10 EN ISO 13132:2011 (E) 6 8.2 Base and side The bases of both the bottom and top dishes shall be, as far as possible, in one plane surface

32、 and the sides shall be perpendicular to the base with a maximum deviation of 3. The bases may be given a slight crown to prevent rocking. 8.3 Edge The edges of the side wall of both bottom and top dishes shall be smoothly ground, fire-polished or clean pressed. The edges shall be in a plane paralle

33、l to their bases. If the edges are finished by burn-off process, there shall not be any tear-drop extending above the plane of cut-off in the bottom dish. In the top dish such protrusion up to 1 mm is permissible. 8.4 Flatness of bottom dishes The inside depth at any two points on the base of the bo

34、ttom dish shall not vary by more than 1,2 mm when measured in accordance with Annex A. 8.5 Performance requirements Petri dishes shall not show visible decrease of transparency, opalescence, iridescence, frosting or cracks after testing by the following procedures: minimum 15 min wet sterilization a

35、t minimum 120 C; minimum 1 h dry sterilization at minimum 160 C. 9 Marking Petri dishes shall be permanently and legibly marked on its sidewall with the following information: a) manufacturers and/or suppliers name and/or trade mark; b) optionally the number of this International Standard, “ISO 1313

36、2”. DIN EN ISO 13132:2011-10 EN ISO 13132:2011 (E) 7 Annex A (normative) Test method for flatness The following type test procedure applies for measurement of flatness of the inner surface of the Petri bottom dish. a) Affix a dial gauge to a stand. b) Place both the measuring equipment and the Petri

37、 dish under test on the same flat and firm surface. c) Lower the dial gauge in such a way that the pointer is pressed against the inner surface of the Petri dish so that some deflection is seen on the pointer. d) Then measure with the dial gauge the difference between the deepest and the highest point of the inner surface which should not exceed the value specified in 8.4.
