The
6、 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-gove
7、rnmental, 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. T
8、he 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 vot

10、d forestry, Subcommittee SC 17, Manually portable forest machinery. BS ISO 17314:2008iv Introduction End-of-life machines contribute to the total volume of waste to be treated. As part of the machine life cycle, it is essential that recovery issues be taken into consideration during the design phase
11、 to ensure environmentally sound treatment. Today, recycling has to be taken into account in addition to safety, emissions and fuel consumption when designing a machine. Consequently, there is need for an indicator to evaluate the ability and potential of new machines to be recovered/recycled. The m
12、ethod for calculating recyclability and recoverability rates specified by this International Standard (similar to the method specified in ISO 22628:2002 for road vehicles) is based on four main stages inspired by the treatment of end-of-life machines. Recyclability/recoverability rates depend on the
13、 design and material properties of new machines and on the consideration of proven technologies those technologies which have been successfully tested, at least on a laboratory scale, in this context. The calculation method of this International Standard cannot in detail reflect the real process tha
14、t will be applied to the machine at the end of its life. BS ISO 17314:20081Manually portable forest machinery Recyclability and recoverability Calculation method 1 Scope This International Standard specifies a method for calculating the recyclability rate and the recoverability rate of manually port
15、able forest machinery, with each rate being expressed as a percentage by mass (mass fraction in percent) of the machine. The calculation can be performed by the machine manufacturer when a machine is initially put on the market. It does not include fluids. 2 Terms and definitions For the purposes of

26、chine are calculated through the following two steps, with components or materials able to be taken into account at each step. Step 1: dismantling (mD,Rand mD,E). Step 2: shredding (mS,Rand mS,E). For the determination of partial mass only, mass fractions of 10 g or more are reported. NOTE The disma
27、ntlability of the machines is usually limited to easily accessible components such as the cutting equipment. For metals separation and non-metallic residue of the remaining parts of a product, shredding is deemed to be the predominant method. 4.2 Materials breakdown The materials breakdown of the ma
28、chine is established by classifying all the materials composing the machine into the following three categories: a) metals; b) non-metals; c) other components, materials or both, for which a detailed material breakdown cannot be established (compounds, electronics, electrics). This breakdown may be
29、done at each step of the calculation for each partial mass mentioned in 4.1. BS ISO 17314:20084 4.3 Calculation of recyclability/recoverability rate 4.3.1 Recyclability rate Calculate the recyclability rate, Rcyc, of the machine, as a percentage by mass (mass fraction in percent), using the formula:

31、large scale worldwide. Therefore, polymers, elastomers and other modified organic natural materials can potentially be recovered through those technologies.
