ISO 10987:2012 地球を動かす機械—持続可能性—用語、持続可能性の要因、および報告 | ページ 6

3.1

sustainability

balance between social, environmental and economic needs that optimizes the current quality of life without sacrificing future quality of life

3.2

machine load factor

parameter used to indicate how a machine is working relative to the capability of the machine, defined by the manufacturer for different types of machine applications, generally using three load factor categories — low, medium and high

Note 1 to entry: It is usually expressed as a percentage of maximum machine capability.

3.3

machine productivity

work performed by a machine as a function of time

3.4

remanufacturing

reconditioning process for a component to return it to a level making it suitable for re-use

3.5

re-use

any operation by which component parts of end-of-life machines are used for the same purpose for which they were conceived

[SOURCE:ISO 16714]

3.6

life cycle assessment

compilation and evaluation of the inputs, outputs and the potential environmental impacts of a product system throughout its life cycle

3.7

end-of-life machine

machine that has completed its useful life and is taken out of service for disposal

[SOURCE:ISO 16714]

3.8

recycling

reprocessing in a production process of the waste materials for the original purpose or for other purposes, excluding processing as a means of generating energy

[SOURCE:ISO 16714]

3.9

recyclability

ability of component parts, materials or both that can be diverted from an end-of-life stream to be recycled

[SOURCE:ISO 16714]

3.10

useful life

period in which a machine is economical to continue to use

Note 1 to entry: The determination of useful life can vary depending on user needs.

3.11

energy efficiency

effectiveness of converting energy into useful work

3.12

greenhouse gas

GHG

gaseous constituent of the atmosphere, both natural and anthropogenic, that absorbs and emits radiation at specific wavelengths within the spectrum of infrared radiation emitted by the earth's surface, the atmosphere, and clouds

Note 1 to entry: For the purposes of this International Standard, GHGs are the six gasses listed in the Kyoto Protocol: carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF₆).

3.13

recovery

reprocessing in a production process of the waste materials for the original purpose or for other purposes, together with processing as a means of generating energy

[SOURCE:ISO 16714]

3.14

recoverability

ability of component parts, materials or both that can be diverted from an end-of-life stream to be recovered

[SOURCE:ISO 16714]

3.15

co₂ equivalent

common unit of measure for greenhouse gas emission used to calculate the total greenhouse gas effect (global warming potential) of different greenhouse gas emissions

3.16

global warming potential

GWP

relative measure of how much heat a greenhouse gas traps in the atmosphere
