BS EN 14930:2007+A1:2009EN 14930:2007+A1:2009 (E) 4 Introduction This European Standard is a type C standard as stated in EN ISO 12100. Products with built-in
21、engines or other heat-sources often show hot surfaces. If such a surface is touched by the unprotected skin, burning of the skin can occur. To avoid skin burning protective measures should be applied, especially in cases when the user of the product is not aware of the risk of burning. So it is esse
22、ntial to assess the risk of burning when using a product with a built-in heat source and to apply protective measures if necessary. This European Standard provides a test method to identify the touchable hot surfaces. Guidance for human response to contact with hot surfaces is given in EN 13202. C-t
23、ype standard writers should consider making an exception from this test for parts or systems which can not be guarded (e.g. the inside and the end of exhaust pipe outlet). The aim of this European Standard is that it will be referenced in the type C standards. BS EN 14930:2007+A1:2009EN 14930:2007+A
24、1:2009 (E) 5 1 Scope This European Standard specifies a method for combustion engine driven pedestrian controlled and hand-held machines with or without back pack power unit used in agriculture, forestry and gardening to determine those parts of the surfaces identified by the product specific standa
25、rds that are hot surfaces and can be touched unintentionally by an operator during normal operation. This European Standard is only applicable together with product specific standards for the categories of machines specified above. This European Standard does not specify which surfaces shall be asse
26、ssed. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

For
29、the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003, EN 13202:2000 and in product specific standards directly applicable to that type of machine, if available, and the following apply. 3.1 normal operation use of the machine which is reasonably foreseeable, as seen
30、by the manufacturer, and which is consistent with such activities as starting, stopping, fuelling, connecting to (or disconnecting from) a power source and performing its application 4 Principles This European Standard identifies, with the use of a test cone, the touchable hot surfaces. Surfaces whe
31、re the contactable area exceeds 10 cm2and of which the temperature exceeds the acceptable values for inadvertent contact are detected. BS EN 14930:2007+A1:2009EN 14930:2007+A1:2009 (E) 6 5 Test equipment 5.1 Temperature measuring equipment The measurement of the surface temperature shall be carried
32、out by means of an electrical thermometer with a contact sensor made of metal and insignificant heat capacity. The accuracy of the instrument shall be within the range of 2 C. NOTE The data presented in this European Standard have been evaluated using the above mentioned measuring facility and resul
33、ts obtained by other techniques may not be suitable for comparison with the data. 5.2 Test cone The test cone shall have the dimensions as given in Figure 1. Dimensions in millimetres Figure 1 Test cone 6 Test procedure 6.1 Determination of touchable surfaces The surfaces to be checked shall be spec
34、ified by the product specific standards. The test cone according to 5.2 shall be moved in any possible direction towards the hot surfaces specified for testing. Mark the areas touchable with the test cone tip or conical surface. BS EN 14930:2007+A1:2009EN 14930:2007+A1:2009 (E) 7 6.2 Determination o
35、f temperature of touchable surfaces Measure the temperatures of the touchable surfaces identified in 6.1, under the following conditions: the test shall be conducted without the influence of sunlight with an air speed of max. 5 m/s and at 20 C 5 C ambient temperature; the machine shall be stationary
36、 with the tools operating, unloaded and running at maximum operating engine/motor speed. The operating conditions shall be recorded in the test report; the machine shall be operated until temperatures have stabilised for normal operation of the machine before testing; the temperature (T) shall be de
37、termined by correcting the measured temperature (TM) depending on the ambient temperature (TA) at the time of the test as follows: T = TM (TA 20) where TMis the measured temperature in C; TAis the ambient temperature in C; when measuring the surface temperature care shall be taken that good contact
38、is established between the sensor and the surface. The use of appropriate force and the use of a conducting paste may be necessary for this purpose. The area of contact should lie flat on the surface and shall not become canted. The measured value should not be read until temperature equilibrium bet
39、ween the surface and the sensor has been reached. To reach this equilibrium more quickly it may be convenient to heat the contact sensor of the measuring instrument at a different point of the hot surface before carrying out the actual measurement; mark the surfaces with temperatures higher than bur
40、n threshold values for up to 0,5 s contact period as given in Annex A and Annex B of EN 13202:2000. These surfaces are identified as hot surfaces; measure and record the area of the marked surface(s). If the area is interrupted the procedure in 6.3 shall be followed. 6.3 Determination of area for in
41、terrupted surfaces If a marked surface (with area A1) consists of multiple separate surfaces of which the sum of the areas (A2) exceeds 80 % of A1, then A1shall be considered as one uninterrupted area (see Figure 2). Surfaces whose structure does not allow a ball with 2 mm diameter to penetrate more
42、 than 2 mm below highest parts of the structure shall be considered as part of A1(see Figure 2).
