Protection of the environment is taken in a very broad sense. Provisions need to be restricted to a genera
17、l guidance. Limit values are specified in national laws. It is recommended that manufacturers develop an environmental management policy. For guidance see the EN ISO 14000- series. It has been assumed in the drafting of this Technical Specification that the execution of its provisions is entrusted t
18、o appropriately qualified and experienced people. Some of the environmental aspects also have an implication for occupational health and safety. PD CEN/TS 16765:2015CEN/TS 16765:2015 (E) 5 1 Scope Protection of the environment needs to be considered during the total life-cycle of a particular produc
19、t, e.g. impact on the environment including expenditure of energy during all phases of its life-cycle, from mining of raw materials, production, testing, packaging, distribution, maintenance and use, end-of-life disposal and recycling of materials, etc. This Technical Specification provides informat
20、ion on the environmental aspects of equipment and accessories produced for the LPG industry. The following are addressed: a) design; b) manufacture; c) packaging; d) use and operation; and e) disposal. 2 Normative references The following documents, in whole or in part, are normatively referenced in
21、 this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 14717, Welding and allied processes Environmental check list 3 Terms and defini

24、product system throughout its life-cycle 3.4 prevention of pollution use of processes, practices, techniques, materials, products, services or energy to avoid, reduce or control (separately or in combination) the creation, emission or discharge of any type of pollutant or waste, in order to reduce a
25、dverse environmental impacts PD CEN/TS 16765:2015CEN/TS 16765:2015 (E) 6 Note 1 to entry: Prevention of pollution can include source reduction or elimination, process, product or service changes, efficient use of resources, material and energy substitution, reuse, recovery, recycling, reclamation an
26、d treatment. 3.5 packaging all items made of any material of any nature to be used for the containment, protection, handling, delivery and presentation of goods, from raw materials to processed goods, from the producer to the user or the consumer Note 1 to entry: In this report the goods are referre
27、d to as “packaged product” or just “product”, in order to distinguish it from the packaging. 4 Environmental aspects to be considered for systematically addressing environmental issues There is a need to reduce the potential adverse impacts on the environment of a product that can occur during all s
28、tages of its life. The potential environmental impacts of products can be reduced by taking into account environmental issues. The impact on the environment from the product life-cycle is caused by: depletion of resources; and pollution including, air emissions, effluent, waste materials and other r
29、eleases. Each of the aspects of the product life-cycle shall be examined in order to reduce these impacts on the environment, referred to as a life-cycle assessment. These include: design; procurement, raw material acquisition, recycling of materials; production and testing; packaging and distributi
30、on; maintenance and use; and end-of-life disposal, reuse or recycling. Prevention of pollution can take many forms and can be incorporated at all stages of the product life-cycle. For example, hazardous, toxic or otherwise harmful substances and materials prescribed in product standards should be su
31、bstituted by other less harmful substances and materials, whenever possible and feasible, as long as it can be demonstrated that at least an equivalent level of quality and safety can be provided and any applicable regulations do not impair such substitution. 5 Design Product design is the strongest
32、 tool for avoiding potential environmental impacts at all stages of the product life-cycle. There are several approaches to product design that consider elements of resource conservation and prevention of pollution. Manufacturers should develop an environmental management policy; for guidance see th
33、e EN ISO 14000- series. The design of LPG equipment and accessories should take account of the following: PD CEN/TS 16765:2015CEN/TS 16765:2015 (E) 7 procurement; minimizing the use of materials; efficient transport of the finished product; minimizing the environmental impact of in service maintenan
34、ce; and minimizing the environmental impact of end of life disposal. The LPG equipment and accessories shall be designed so that its use is straightforward with minimal complexity, reducing the risk of accidental misuse that could lead to adverse environmental impacts. 6 Procurement The manufacturer
35、 should endeavour to acquire materials and components from suppliers who have a declared environmental policy, see EN ISO 14021, EN ISO 14024 and EN ISO 14025. Table 1 provides recommendations related to the selection and acquisition of raw materials, pre-manufactured materials and components. It is
36、 important in the procurement of raw materials that the depletion of resources is considered when choosing the particular materials for the product. The manufacturer should endeavour to minimize wastage of material by selecting appropriately sized materials related to the finished parts required for
37、 manufacture. Unavoidable waste/scrap material should be recycled. Materials reuse, ease of recycling and recovery are important factors that should influence the choice of materials. Materials should be chosen to ensure that end-of-life disposal is minimized. PD CEN/TS 16765:2015CEN/TS 16765:2015 (
38、E) 8 Table 1 Acquisition of raw material, pre-manufactured material and components Recommendations Examples of choices and limitations Using the smallest possible amounts of materials A decision should be made when a higher amount of a material A with abundant resources is compared with a smaller am
39、ount of a material B with very limited resources. Using materials which can be easily recovered or recycled Choices should be made for packaging when, a light-weight flexible packaging disposed of by incineration or land-filling is compared with a heavy rigid container, e.g. a cardboard box or a ste
40、el can that is easy to recycle. Using recycled or reused materials As a criterion, the end-of-life recycling rate should be preferred to the percentage of recycled material in a product. A lack of knowledge of the quality of the recycled material e.g. the chemical composition (hazardous substances,
41、contaminations) may limit the use of those materials. Using renewable resources and minimizing the use of non-renewable raw materials This criterion is only valid if renewable resources are sustainably managed and are not depleted faster than they can re-grow. Checking the merits of a reusable versi
42、on of the product Choices should be made if a reused product consumes more energy than a new product. Restricting the use of hazardous substances to the unavoidable functional need, with special regard to toxic and very toxic, carcinogenic, mutagenic and reprotoxic substances Choices should be made
43、if small traces of hazardous materials are dissolved in recycled materials. In such cases, the bioavailability of the dissolved hazardous materials needs to be considered. Selecting raw materials to optimize durability and lifetime No known limitations or decision conflicts/No example provided. Usin
44、g standardized elements, parts, components for easy maintenance, reuse or recycling No known limitations or decision conflicts/No example provided. Minimizing the number of different materials No known limitations or decision conflicts/No example provided. Reusing components in or from other product
45、s Choices should be made if a reusable component uses more energy or has other increased environmental impacts compared with a new component. Minimizing the use of energy and the emission of greenhouse gases during raw material acquisition A decision conflict may occur, for example, between the use
46、of steel and aluminium in road and rail vehicles, where energy use in the operational stage may be a critical environmental aspect. Prescribing performance criteria, which includes environmental performance, rather than materials or substances to be used This usually requires comprehensive specifica
47、tion by the producer and further testing of the product. Technical performance and environmental performance criteria can contradict each other. PD CEN/TS 16765:2015CEN/TS 16765:2015 (E) 9 7 Production 7.1 General The scarcity of water, especially of fresh water from surface or underground sources,
48、is critical in many regions of the world. The efficient use of water in the different stages of the product life-cycle needs to be considered, where pertinent. In addition, the availability of water where it is needed requires the use of energy to transport it. Noise levels from the production proce
49、ss should be evaluated and measures put into place to minimize the impact upon the external environment. Where heat treatment is performed, the process shall be designed to minimize energy consumption, use of coolants, and ensure the environmentally friendly disposal of insulating material and other waste. 7.2 Measures to reduce environmental impact Table 2 provides recommendations related to the production and testing of products.
