In addition, the machine shall be designed according to the principles of EN ISO 12100 for relevant but not significant hazards, which are not dealt with by this document (e.g. sharp edges of the machine frame). NOTE For guidance in connection with risk reduction by design, see Clause 4 of EN ISO 12100-2:2003, and for safeguarding measures, see Clause 5 of EN ISO 12100-2:2003
Parts are considered stable when conditioned in the location where testing is carried out for a period of 24 hours and the ambient temperature is maintained at not less than 15°C.
Machines shall also be marked according to 6.2 and carry warnings according to 6.3.The instruction handbook to be provided with the machine shall comply with 6.1. 5.2 All machines The infeed and discharge opening shall be guarded to prevent contact during normal operation taking into account the safety distances conforming to 4.2.4.1 and 4.2.4.3 of EN ISO 13857:2008.
All guards shall be permanently attached to the machine and shall not be detachable without the use of tools. The opening of guards shall require the use of a tool.
If regular access (see 6.1 for user maintenance) to moving parts is needed (e.g. for removing debris), guards shall be equipped with interlocks in compliance with EN 1088, which disable the drive to the relevant moving parts when accessing the moving parts. The safety-related control system of the interlocked guards shall comply with at least category 1 of EN ISO 13849-1:2008. Compliance is checked by inspection and measurement. 5.3 Hot parts guarding Any metallic surface of the machine that has a temperature of over 80 ºC, or plastic part that has a temperature of over 94 ºC, shall be considered as a hot surface. Such surfaces shall be guarded or designed so that the test acceptance in EN 14930 is met. Surface temperature and compliance shall be determined in accordance with EN 14930. The inside and the end of the exhaust pipe are not considered accessible hot parts and therefore do not have to pass the test of EN 14930. SIST EN 15503:2010

5.4.1 Requirements The casing including all detachable guards shall have adequate mechanical strength and be constructed to withstand such rough handling that may be expected in normal use. Compliance shall be checked by the test in 5.4.2. 5.4.2 Casing strength and rigidity test of hand-held and backpack powered machines The machine is rigidly supported and three blows are applied to every point of the casing that is likely to be weak with an impact energy of 1,0 J ± 0,05 J by means of the spring hammer as specified in IEC 60068-2-75:1997. To ensure that the machine is rigidly supported, it may be placed against a solid wall of brick, concrete or similar material. In that case a sheet of polyamide is tightly fixed to the wall, care being taken to ensure that there is no appreciable air gap between the sheet and the wall. The sheet shall have a Rockwell hardness of HR 100, a thickness of at least 8 mm and be sufficiently large to ensure that all parts of the machine are supported.
No parts of the guarding (casing) that are necessary for compliance with the requirements of this European Standard shall have become detached and no visible cracks shall have developed in these parts. It is not necessary for the machine to be operable after the test but, if it is operable, then immediately following this test, it shall be run at its maximum speed for 30 s and again, no parts of the machine that are necessary for safe operation shall become detached and no visible cracks shall have developed in these parts.
If there is doubt as to whether a defect has occurred by the application of the preceding blows, this defect is neglected and the group of three blows is applied to the same place on a new sample which shall then withstand the test.
If an inner cover is protected by a decorative cover, the test shall be done with the decorative cover removed Damage to the finish, small dents and small chips that do not adversely affect the function of the guard are ignored. Cracks not visible to the naked eye are ignored. 5.5 Structural integrity of vacuums
5.5.1 Requirements The machine shall have sufficient structural integrity to withstand the rigours of normal operation and break- up of the fan.
No part of the machine shall have become detached and there shall be no visible holes, tears or cracks in the enclosure surrounding moving parts or in the debris collector. Compliance shall be checked by the test in 5.5.2. 5.5.2 Structural integrity test A structural integrity test shall be carried out on all machines by vacuuming up ceramic prisms with triangular sides and a prism height of 6,5 mm ± 0,8 mm and a mass of 0,4 g ± 0,02 g (see Figure 1).
For machines the vacuum power of which is not capable of sucking up a sample prism the test does not apply. If the machine has a removable facility for shredding, the machine shall be tested with and without this facility. SIST EN 15503:2010

5.8 Noise 5.8.1 Reduction by design and protective measures The machine shall be so designed and constructed that risks resulting from the emission of airborne noise are reduced to the lowest level taking account of technical progress and the availability of means of reducing noise, in particular at source. The main sources causing noise for the machines covered are:  air intake system;  motor/engine cooling system;  fan;  vibrating surfaces;  shredding means. NOTE EN ISO 11688-1 [5] gives general technical information on widely recognized technical rules and means for the design of machines of low-noise emission.
5.11.2.2 Test method The requirements shall be checked by inspection and using the test probe B of IEC 61032:1997.
Test acceptance: the test probe shall not make contact with high voltage parts of the circuit including spark plug terminals
5.12 Fuel tank openings The fuel tank opening shall be at least 20 mm diameter and the cap shall have a retainer. The design of the cap shall be such that no leakage occurs in all working positions while the machine is running and during transport. The filler opening shall be located in such a way that the filling of the tank with a funnel is not obstructed by other components. Seepage from fuel tank ventilation systems is not regarded as leakage. Compliance shall be checked by inspection and functional test. 5.13 Additional requirements for back-pack powered units 5.13.1 Handgrip The backpack unit shall be equipped with a handgrip surface or structure specifically designed for the operator's hand to allow the operator to grasp the back-pack power unit to place it on his back or take it off.
Compliance shall be checked by inspection and functional test. 5.13.2 Back-pack support and harness The harness shall be designed to prevent slipping and be adjustable so that pressure can be evenly distributed on the operator. Harnesses of backpack units shall be equipped with a quick release mechanism ensuring the unit to be released quickly from the operators in the event of emergency. The quick release mechanism shall only allow separation by deliberate action of the operator. Compliance shall be checked by inspection and by functional test. 6 Information for use 6.1 Instruction handbook Each machine shall be provided with information and instructions for normal use including warnings against particular hazards of use and instructions for operating, servicing and maintenance that comply as appropriate with 6.5 of EN ISO 12100-2:2003.
