35、ingLCA of auto parts incorporating weight changes due to materialcomposition, manufacturing technology, or part geometryMay 2014 viiPrefaceThis Guideline establishes the requirements for conducting comparative life cycle assessments (LCA) of auto parts incorporating weight changes due to changes in

36、material composition, manufacturing technology, or part geometry, and in conformance with the International Organization for Standardization (ISO) 14040 series of standards. Although informative in nature, this Guideline has been written in mandatory language to facilitate adoption by organizations.

37、 CSA Group acknowledges that the development of this Guideline was made possible, in part, by the financial support of Natural Resources Canada (NRCan).This Guideline was prepared by the Technical Development Group on Auto Parts, and reviewed for technical accuracy and practical feasibility by a Pee

38、r Review Panel.Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.(2) Although the intended primary application of this Guideline is stated in its Scope, it is important to note that it remains the responsibility of the users of the Guideline to judge i

39、ts suitability for their particular purpose.(3) To submit a proposal for change, please send the following information to inquiriescsagroup.org and include “Proposal for change” in the subject line:(a) designation (number);(b) relevant clause, table, and/or figure number;(c) wording of the proposed

41、s for conducting LCA of auto parts incorporating weight changes due to material composition, manufacturing technology, or part geometry0Introduction0.1The purpose of this Guideline is to provide rules for quantifying the potential environmental impacts of weight changes of automotive parts, componen

42、ts, assemblies, and subassemblies (collectively referred to as “auto part”), manufactured by or for North American automotive OEMs (original equipment manufacturer), and either installed in vehicles or sold on the aftermarket for use in North America, due to changes in material composition, manufact

43、uring technology, or part geometry.0.2This Guideline establishes rules and requirements for conducting comparative life cycle assessment (LCA) studies with the objective of providing clear and consistent guidance for assessing potential environmental impacts throughout the cradle-to-grave life cycle

44、 of an auto part with a focus on weight differences between design options. The life cycle stages include(a) raw material acquisition;(b) production;(c) use; and(d) end-of-life treatment (including recycling and final disposal).0.3This Guideline is primarily aimed at conducting comparative LCA studi

45、es on auto parts that are(a)intended to be installed in a vehicle, for the purpose of supporting internal design decisions in the vehicle development cycle and possible external communication; or(b) already installed in a vehicle, for the purpose of external communication.Interested parties include

46、auto part OEMs and suppliers, auto manufacturers, industry associations, governmental organizations, policy makers and other stakeholders who desire reliable information on auto parts.In conformance with ISO 14044, Clause 6.3, a panel of interested parties conduct critical reviews on LCA studies whe

47、re the results are intended to be used to support comparative assertion intended to be disclosed to the public.0.4This Guideline enables LCA studies to be conducted using agreed upon and uniform rules, and allows for the comparison of LCA study results between auto parts. Potential uses may include,

48、 but are not limited to(a)design and development decisions for auto parts and automobiles;SPE-14040-14 2014 CSA Group2 May 2014(b) evaluation of materials choices and materials substitution options;(c) evaluation of fabrication and manufacturing options;(d) assessment of alternative product configur

49、ations;(e) benchmarking for programs aimed at reducing environmental impacts; and(f) educational purposes, so that a greater understanding of life cycle impacts will inform sourcing and purchasing decisions.0.5This Guideline defines specific rules and requirements for:(a) the specification of performance characteristics and description of an auto part;(b) definition of the functional unit and the reference flow for LCA of an auto part;(c) the system boundaries for the LCA of an auto part;(d) predetermined parameters to be used
