BS EN 16524-2020 Mechanical products一Methodology for reduction of environmental impacts in product design and development. 6.2.2.4 Scoring of environmental aspects 6.2.2.4.1 Using the algorithm Complete the environmental questionnaire stated in Annex A, answering all the questions using the choices given in the questionnaire only (the answer don’t know refers to the worst case scenario) and justify your answers where applicable. These answers are used to produce the reference product’s SEA from the algorithm given in Annex B and also to provide input to the company’s assessment on design options and on the overall assessment. Apply the analysis algorithm given in Annex B based on the answers to the questions (the reference of the question from Annex A is identified on the algorithm). 6.2.2.4.2 Register the scores (1 to 4) obtained for each environmental aspect NOTE 1 The so obtained SEA gives a description of the most important environmental aspects to consider during the ecodesign of the product, even if these aspects are already partly considered by the company. EXAMPLE 1 A product is made of renewable RM; however, the score for RM environmental aspect is at level 4 in the SEA. This score of 4 means that RM aspect plays a very important role in the global SEA of the product. compared with the other aspects. If a company has already chosen renewable kM. It shows that this choice was relevant and it will be possible to take advantage of it when ranking the design options (see 6.3), but this choice does not modify the SEA. EXAMPLE 2 A product has a very low energy consumption compared with another product of the product line; however, the score for the environmental aspect U is at level 4 for both. The score of 4 means that U aspect (related to energy consumption) plays a very important role in the SEA of both products, compared with the other environmental aspects. This score does not allow the conclusion that one of both products is more energy-efficient. For that, the use of indicators is necessary (see 6.4). NOTE 2 These scores can be given In graph format (see FIgure 6). 6.2.3 Documentation of Step 1 The following documents shall be available as a result of Step 1: — BOM of the reference product; — completed questionnaire; — SEA of the reference product; They shall be used as inputs for Step 2. 6.3 Step 2: selection/ranking...
