These principles shall be considered when allocating functions to operator and machine degree of automation in the basic design. It also provides a strategy for standard makers. One example of this is Clause 5. Achieving the objectives of risk reduction and a favourable outcome of risk comparison applied when practicable gives confidence that risk has been adequately reduced.

Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards. The information for use shall be given in the language s of the country in which the machine will be used for the first time and in the original version.

Following the application of the three-step method, adequate risk reduction is achieved when? The selector may be replaced by another selection means which restricts the use of certain functions of the machinery to certain categories of operators for example, access codes for certain numerically controlled functions.

Where this is not possible, machines shall have built-in platforms, stairs or other facilities to provide safe access for those tasks; however, care should be taken to ensure that such platforms or stairs do not give access to danger zones of machinery.

Clause 5, ‘Strategy for risk reduction,’ contains what might be termed the real ‘meat’ of the standard. Disturbances which can be generated by those conditions include insulation failures and temporary 12010-1 permanent failures in the function of control system components. Factors to be taken into account when estimating the occurrence of a hazardous event em, among others, a b c d reliability and other statistical data, accident history, history of damage to health, and comparison of risks see 5.

In certain applications, such as high-voltage switchgear, this principle cannot be followed, in which case other measures should be applied to achieve the same level of confidence een the stopping or slowing down.

When the application requires reprogramming by the user, the access to the software dealing with safety functions should be restricted for example, by locks or passwords for the authorized persons. Minimum gaps to avoid crushing of parts of the human body.

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the 11200-1. The design of the programmable electronic control system shall be such that the probability of random hardware failures and the likelihood of systematic failures that can adversely affect the performance of the safety-related control function s is sufficiently low.

Cycle initiation by sensitive protective equipment shall be subject to the following conditions: In order to offer more detailed information on the type of hazards, there are two additional columns that correspond to the origin of the hazard and its potential consequences.

It shall not exclude uses of the machine that can reasonably be expected from its designation and description and shall also warn about the risk which would ne from using the machine in other ways than the ones described in the information, especially considering its reasonably foreseeable misuse. Annex A provides a schematic representation of a machine, though this is likely to be of limited use to most readers, and there are 14 pages of a trilingual English, German and French index of specific terms and expressions used in the standard, which is unlikely to be of use to most machine designers.

NOTE 3 The terms for types of guards are defined in 3. An example of this is positive opening operation of switching devices in an electrical circuit see IEC and ISO NOTE 1 The ideal application of these principles requires knowledge of the use of the machine, the accident history and health records, available risk reduction techniques, and the legal framework in which the machine is to be used. NOTE 2 Adequate protective measures associated isp each of the operating modes and intervention procedures reduce the possibility of operators being induced to use hazardous intervention techniques in case of technical difficulties.

ISO shall not be held responsible for identifying any or all such patent rights. NOTE 2 Machine start-up during normal sequence of an automatic cycle is not unintended, but can be considered as being unexpected from the point of view of the operator. See IEC as regards marking of electrical e. Looking in detail at Part 1, there are three main clauses in addition to the scope and normative references. The use of this comparison method does not eliminate the need to vs the risk assessment process as described in this International Standard for the specific conditions of use.

Tables should be adjacent to the relevant text. The designer shall identify hazards taking into account the following.

Control devices shall be designed and located to prevent their being used as aids for access. Please download Chrome or Firefox or view vs browser tips. These three steps are:. Information for use Where risks remain despite inherently safe design measures, safeguarding and the adoption of complementary protective measures, the residual risks shall be identified in the information for use.
