The work of preparing International Standards is

15、 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 part

16、 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 pr

17、epare 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 that

18、 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.

32、 1 and Figure 2) and smoothly finished. They shall be symmetrical about the axis which shall be perpendicular to the thought plane of the base. 8.2 Base Desiccators shall have a slightly concave base enabling the desiccator to stand vertically without rocking or spinning on a plane horizontal surfac

33、e. To increase the stability and protection against mechanical damage or cracking, extra glass may be provided externally to form a protective rim at the base, and/or the outer surface of the base shall be picked along the circumference. 8.3 Side The side of the desiccators shall be stepped to accom

34、modate perforated desiccator plates (e.g. in accordance with national standards) without rocking, in a plane parallel to the base. The upper part of the side above the step shall rise in the approximate form of a vertical slightly tapered cylinder and end in a horizontal flat flange. See Figure 1 an

35、d Figure 2. 8.4 Lid The lid of desiccator shall be part-spherical in shape. Its rim shall form a flat flange the surface of contact of which shall match that of the flat flange of the body of the desiccator evenly. The lid shall be provided at the top either with a vacuum connection or with a knob o

36、f minimum diameter 38 mm for ease of handling. The knob may be solid or hollow. 8.5 Flat flange and tightness The vacuum-tight surfaces of the flanges of the body and the lid shall be separately ground plane so that they are interchangeable. They shall be ground fine so that the assembled desiccator

37、, or its body or lid when tested separately, complies with the following requirement. The leakage rate of closed desiccators shall not exceed 3 mbar l s1. This is to be tested with paired bodies and lids, selected at random and with the flange face dry, in accordance with national or International S

38、tandards. The flat flange of the body may be furnished with a ring-groove to incorporate a matching elastomeric seal. 8.6 Vacuum connection Desiccators of Type 1 shall have an opening for vacuum connection located either in the top centre of the lid or in the side wall of the body at a height equal

39、to h1(see Figure 1). The opening for the vacuum connection shall have the form of a conical ground glass socket size 24/29 in accordance with ISO 383, or of an external screw thread in accordance with suitable national or International Standards, or of a socket for take-up of a rubber stopper, or BS

The bore size shall be minimum 2 mm and the internal diameter of the tube shall match the bore size. 8.7 Pressure strength Vacuum desiccators (Type 1)

41、 shall be capable of resisting an external pressure of 2 bar for 60 s or an external pressure of 3 bar for 10 s. Testing shall be conducted in accordance with Annex A. 8.8 Protective coating For protection against mechanical damage (impact or shock), the body and lid of desiccators may have an exter

42、nal plastic coating. 9 Thermal shock endurance Desiccators shall be type tested to comply with a thermal shock endurance of 80 C in accordance with ISO 718. 10 Marking and packaging 10.1 Desiccators shall be permanently and legibly marked on the body and the lid with the following: a) manufacturers

43、and/or suppliers name and/or trade mark; b) nominal size or designation; c) type (vacuum or non-vacuum desiccator); d) optionally the number of this International Standard, “ISO 13130”. 10.2 Desiccators shall be packed individually as agreed to between the purchaser and the supplier to protect them

44、from damage during transit and storage. 11 Appearance of used desiccators Before a vacuum is applied to the desiccator, it shall always be checked visually to verify that its internal and external surfaces are free from defects such as chipping, cracks or grooves. Particular attention shall be paid

45、to the base and to the side wall at the step. Damaged desiccators shall not be used. BS EN ISO 13130:2011ISO 13130:2011(E) 6 ISO 2011 All rights reservedAnnex A (normative) Type test for pressure strength A.1 General The desiccator is tested in a pressure vessel by subjecting it to a hydraulic exter

46、nal pressure of 2 bar for 1 min or an external pressure of 3 bar for 10 s. A.2 Apparatus A.2.1 Pressure vessel, with a pressure gauge connected to a water reservoir fitted with a ram pump and a release valve discharging back into the reservoir. The lid of the pressure vessel can be fastened to the v

47、essel by means of wing nuts for ease of operation. The recommended apparatus is illustrated in Figure A.1. A.3 Procedure Assemble the desiccator after cleaning and greasing the flange faces (and the cone and socket in case of Type 1) and close the desiccator at atmospheric pressure. To ensure submer

48、sion, hold the desiccator in the pressure vessel in some holding device or, alternatively, place weights wrapped in paper or cloth inside it. Having placed the desiccator in position and fastened the lid, fill the pressure vessel with water and bring up the pressure to 2 bar by working the ram pump

49、and release it immediately after 1 min. A.4 Result The desiccator shall be considered to have satisfied the requirement of the test if it withstands the pressure of 2 bar for 1 min. Alternatively, the test may be performed at 3 bar for 10 s.
