ISO 11148-5:2011(E) iv © ISO 2011 – All rights reserved 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 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 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 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 that 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. ISO 11148-5 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools, machines and equipment, Subcommittee SC 3, Pneumatic tools and machines.

In addition, the machine shall be designed in accordance with the principles of ISO 12100 for relevant, but not necessarily significant, hazards, which are not dealt with by this part of ISO 11148. The measures adopted to comply with the requirements of Clause 4 shall take account of the state-of-the-art. It is recognized that optimizing the design with respect to some safety measures can result in a degradation of performance against other safety requirements. In such cases, it is required to strike a balance between the various requirements in order to achieve a power tool design that satisfies each requirement, so far as is reasonably practicable, and remains fit for purpose. 4.2 Mechanical safety 4.2.1 Surfaces, edges and corners Accessible parts of rotary percussive drills, except the inserted tool, shall not have sharp edges or angles or rough or abrasive surfaces; see ISO 12100:2010, 6.2.2.1. 4.2.2 Supporting surface and stability Rotary percussive drills shall be so designed that they can be laid aside and remain in a stable position on a plane surface. SIST EN ISO 11148-5:2012

ISO 11148-5:2011(E) © ISO 2011 – All rights reserved 5 4.2.3 Ejection of parts Rotary percussive drills shall be equipped with a retainer or other device to prevent the ejection or falling out of the inserted tool. 4.2.4 Hydraulic fluid ejection Hydraulic systems of the rotary percussive drill shall be enclosed so as to provide protection from high-pressure fluid ejection. 4.2.5 Guards Guards covering the inserted tools are not required to be fitted to a rotary percussive drill. 4.2.6 Power tool construction The rotary percussive drill shall be so designed and constructed as to prevent the loosening or loss of components during expected use, including rough handling and occasional dropping, which can compromise its safety functions. Verification shall be carried out in accordance with 5.5. 4.3 Thermal safety Surface temperatures of parts of the rotary percussive drill which are held during use or that can be inadvertently touched shall follow the provisions of ISO 13732-1 and ISO 13732-3. Rotary percussive drills shall be designed to minimize the cooling effects of exhaust air on the handles and other gripping zones. 4.4 Noise reduction The rotary percussive drill shall be designed and constructed so that the emission of noise is reduced to the lowest level, taking account of technical progress and the availability of means of reducing noise, in particular at source. Principles for designing rotary percussive drills with reduced noise emission are contained in ISO/TR 11688-1 and ISO/TR 11688-2. The noise emission from using rotary percussive drills has three main sources:  the rotary percussive drill itself;  the inserted tool;  the workpiece. NOTE Generally, the noise emitted due to the characteristics of the workpiece cannot be controlled directly by the manufacturer of the rotary percussive drill. Typical sources of noise emitted by the rotary percussive drill itself are a) the motor and drive mechanism, b) the exhaust air or gases, and c) the vibration or impact-induced noise. Where the exhaust air or gases are the major contributor to the noise, means to reduce the noise, for example a silencer or equivalent means, shall be included in the design. SIST EN ISO 11148-5:2012

ISO 11148-5:2011(E) 6 © ISO 2011 – All rights reserved Alternatively, where practicable, the exhaust air or gases may be piped away from the operator in a hose. Vibration-induced noise can often be reduced by vibration isolation and damping. This list is not exhaustive; where alternative technical measures for noise reduction, with greater efficiency, are available, they should be used by the manufacturer. 4.5 Vibration The rotary percussive drill shall be designed and constructed so that the vibration is reduced to the lowest level at the handles and at any other parts of the tool in contact with the operator's hands, taking account of technical progress and the availability of means of reducing vibration, in particular at source. Principles for designing rotary percussive drills with reduced vibration emission are contained in CR 1030-1. Typical sources of vibration emitted by a rotary percussive drill are  impacts,  poorly designed motors, and  resonances in the structure of the machine, particularly the handles and their mounts. The following design features have been found to be effective and should be considered by manufacturers when designing rotary percussive drills: a) reaction masses and springs; b) increasing inertia; c) isolated casing or handles. This list is not exhaustive; where alternative technical measures for vibration reduction, with greater efficiency, are available, they should be used by the manufacturer. 4.6 Materials and substances processed, used or exhausted 4.6.1 Exhaust air or gas Rotary percussive drills driven with compressed air, gas or an internal combustion engine shall be designed in such a way that exhaust air or gases are directed so as not to cause a hazard to the operator and so that any other effects, such as blowing dust and reflected air or gas from the workpiece on to the operator, are minimized. 4.6.2 Dust and fumes So far as is reasonably practicable, the rotary percussive drill shall be designed to facilitate the collection and removal or suppression of airborne dust particles and fumes generated by the work process. The instruction handbook shall include sufficient information to enable adequate control of the risks from dust and fumes. 4.6.3 Lubricants When specifying lubricants, the manufacturer shall take environmental and occupational health aspects into account. SIST EN ISO 11148-5:2012

ISO 11148-5:2011(E) © ISO 2011 – All rights reserved 7 4.7 Ergonomics 4.7.1 Design of the handle Gripping areas of the rotary percussive drills shall be designed to provide convenient, effective means for the operator to exercise full control over the rotary percussive drill. Handles and other parts used for gripping the rotary percussive drill shall be designed to ensure that the operator is able to grip the rotary percussive tool correctly and to perform the expected work. Handles shall suit the functional anatomy of the hand and the dimensions of the hands of the operator population. NOTE Further guidance on ergonomic design principles can be found in EN 614-1. Rotary percussive drills having a mass greater than 2 kg (including the inserted tool) shall be capable of being supported by two hands whilst being lifted or operated. The grip shall be such that normal feed force and reaction torque can be transmitted in an ergonomic way from the hand of the operator to the rotary percussive drill. The strength of a removable handle and the method of fixing it shall be appropriate to the intended principal use. 4.7.2 Suspension device Provision shall be made, where appropriate, to enable the attachment of a suspension device to the rotary percussive drill in order to reduce, where practicable, the physical strain placed on the operator by the weight of the rotary percussive drill. The fitting of a suspension device shall not introduce an additional hazard. 4.7.3 Reaction torque Rotary percussive drills shall be designed so that the effect of reaction torque is reduced as much as possible. This can be done by mounting a support handle or through other suitable means. Rotary percussive drills that can be foreseen to be used in such operations where a harmful reaction torque has to be absorbed by the operator shall have provisions for the attachment of absorbing devices, such as support handles or other suitable means. Pistol grip and D-handle tools shall have a provision for mounting a second handle if the reaction torque absorbed by the operator can exceed 10 N·m. NOTE 1 Provisions for mounting second handles or other suitable means can be required at lower values of reaction torque than indicated above, depending upon factors such as the expected frequency and daily duration of operation, the physique and posture of the operator, the type of joint and the use of accessories. NOTE 2 Recommended force limits for machinery operation are given in EN 1005-3. 4.8 Controls 4.8.1 Start-and-stop device Rotary percussive drills shall be equipped with a single control device to start and/or stop them. It shall be arranged near the handle so that the operator can activate it without releasing the grip on the handles. The start-and-stop device shall be so designed that the inserted tool ceases to be powered when the start-and-stop device is released. Without manual effort and when completely released, the device shall move to the stop position, i.e. shall be of the hold-to-run type. Start-and-stop devices shall be in the stop position or immediately move to the stop position when the rotary percussive drill is connected to the energy supply. SIST EN ISO 11148-5:2012

ISO 11148-5:2011(E) 8 © ISO 2011 – All rights reserved It shall not be possible to lock the start-and-stop device in the running position, with the following exception: rock drills may have a lock-on start-and-stop device. NOTE The lock-on control offers collaring with less exposure to noise, vibration and dust. 4.8.2 Unintentional start The start-and-stop device shall be so designed, positioned or guarded that the risk of unintentional start is minimized. Verification shall be carried out in accordance with 5.4. 4.8.3 Actuating forces For rotary percussive drills that are intended for frequent starts or for use with precision work, the actuating force shall be small.
For rotary percussive drills that are normally used in operations of long duration, the force to keep the start device in the run position should be small. NOTE For further information on trigger forces for control devices, see EN 894-3.
5 Verification 5.1 General conditions for tests
Tests according to this part of ISO 11148 are type tests. 5.2 Noise The noise-emission values shall be measured and declared in accordance with ISO 15744. Compliance with 4.4 may be verified through the comparison of the noise-emission values with those for other machines of the same family or with machines of similar size and performance characteristics. 5.3 Vibration The vibration total value shall be measured and reported in accordance with ISO 28927-10. The vibration-emission value and its uncertainty shall be declared in accordance with EN 12096. Compliance with 4.5 may be verified through the comparison of the vibration-emission values with those for other machines of the same family or with machines of similar size and performance characteristics. 5.4 Unintentional start Compliance with 4.8.2 shall be verified for rotary percussive drills up to 15 kg as follows. The retainer shall be mounted and not removed. Connect the rotary percussive drill to the energy supply and place and maintain it in any possible position on a horizontal plane. Establish that the start-and-stop device cannot initiate running in any of those positions. Operation of the start-and-stop device shall not occur when the rotary percussive drill is pulled across a horizontal plane by its hose. SIST EN ISO 11148-5:2012

 Use of the tool can expose the operator's hands to hazards, including impacts, cuts and abrasions and heat. Wear suitable gloves to protect hands.  Operators and maintenance personnel shall be physically able to handle the bulk, weight and power of the tool.  Hold the tool correctly; be ready to counteract normal or sudden movements and have both hands available.  Maintain a balanced body position and secure footing.  High reaction torque can be developed in the case of stalling.  Keep hands away from the rotating chuck and drill bit.  Release the start-and-stop device in the case of an interruption of the energy supply.  Use only lubricants recommended by the manufacturer.  Personal protective safety glasses shall be used; suitable gloves and protective clothing are recommended.  Avoid direct contact with the inserted tool during and after use as it can become hot.  Sharp tools should always be used.  Unexpected tool movement or breakage of inserted tools can cause injuries.  Avoid unsuitable postures as it is likely for these positions not to allow counteracting of normal or unexpected movement of the rotary percussive drill, such as a sudden break of the inserted tool.  If the application for which the rotary percussive drill is being used can result in the reaction torque upon the operator exceeding the appropriate value according to 4.7.1, a second handle shall be used.  Beware of the risk of being drawn into or trapped by the rotating inserted tool.  Beware of the risks due to whipping of the compressed air hose.  Collaring the drill should be avoided where possible; however, if necessary, exposure should be kept to a minimum.  In cases where the means to absorb the reaction torque are requested, it is recommended to use side handles for pistol grip and D-handle tools whenever possible. In any case, it is recommended to use a means to absorb the reaction torque above 10 N·m.  Warnings shall be given regarding the risk of explosion or fire due to the material being processed. 6.2.2.8 Repetitive motions hazards  When using a rotary percussive drill to perform work-related activities, the operator can experience discomfort in the hands, arms, shoulders, neck or other parts of the body.  While using a rotary percussive drill, the operator should adopt a comfortable posture whilst maintaining secure footing and avoiding awkward or off-balance postures. The operator should change posture during extended tasks; this can help avoid discomfort and fatigue. SIST EN ISO 11148-5:2012
