The work of preparing International Standards

15、 is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take p

16、art in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to

17、 prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility t

18、hat some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

The bases may be given a slight crown to prevent rocking. 8.3 Edge The edges of

33、 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 parallel 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 th

34、e 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 bottom 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

35、 of transparency, opalescence, iridescence, frosting or cracks after testing by the following procedures: minimum 15 min wet sterilization at 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 followi

38、ce 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.
