Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their correspon

25、02-2:1997 BSI 04-2000iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested i
26、n 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 in the work. ISO collaborates closely with the International Electrotechnical Commis
27、sion (IEC) on all matters of electrotechnical standardization. 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. Internatio
28、nal Standard ISO 11102-2 was prepared by Technical Committee ISO/TC 70, Internal combustion engines. ISO 11102 consists of the following parts, under the general title Reciprocating internal combustion engines Handle starting equipment. Part 1: Safety requirements and tests; Part 2: Method of testin
29、g the angle of disengagement. Annex A of this part of ISO 11102 is for information only.

30、py, (c) BSI EN ISO 11102-2:1997 BSI 04-20001 1 Scope This part of ISO 11102 describes the method for testing the angle of disengagement of starting handle equipment i.e. testing of the essential safety requirements according to ISO 11102-1 for reciprocating internal combustion engines for land, rail
31、 and marine use, excluding engines used to propel road vehicles and aircraft. It may be applied to engines used to propel road construction, earth moving machines and for other applications where no suitable International Standards exist. 2 Normative reference The following standard contains provisi
32、ons which, through reference in this text, constitute provisions of this part of ISO 11102. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part of ISO 11102 are encouraged to investigate the possibility of a
33、pplying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 11102-1:1997, Reciprocating internal combustion engines Handle starting equipment Part 1: Safety requirements and tests 3 Testing of the disengag
34、ement travel 3.1 Apparatus The test shall be carried out on the type of reciprocating internal combustion engine for which the starting handle was designed. The engine shall be mounted on test equipment as generally indicated in Figure 1 or Figure 2, as appropriate. 3.2 Procedure Set the stop (3) so
35、 that the starting handle grip lies horizontally. For the first test hang a mass (5) of 5 kg from the centre of the grip (2). Turn the engine flywheel (6) smoothly in its reverse direction using the crankhandle (7). Measure the distance moved before disengagement occurs on the scale (4) using a mark
36、 on the shank (1) of the starting handle. Repeat the above procedure with a 50 kg mass. NOTEThe direction of rotation of the crankhandle may differ from that of the engine (as defined in ISO 1204) depending on the coupling of the crankhandle to the engine (e.g. it may be linked to the crankshaft, ca
37、mshaft, geardrive or beltdrive). 4 Testing of the angle of disengagement The angle of disengagement shall either be calculated from the measured travel, or shall be measured directly using the method described in clause 3, with the linear scale replaced by an angular scale. 5 Tolerances The angle sh
38、all be measured to the nearest degree, and the travel to 2 mm. 6 Number of tests 10 tests shall be carried out for each test mass. 7 Test report The largest angle measured and travel determined during the 10 tests shall be recorded on the test report (see ISO 11102-1).
