Required Data

Part Specific Emissions

Purpose: The purpose of this exercise is to enter emissions that are specific for the part. For a manufactured part there could be emissions that are generated during the production process even though it is not included in the routing or in the product structure. These emissions can be registered as Part Specific Emissions.

Windows:
Part Eco-footprint

1. On the Part Specific Emission tab, enter emission substance PBDE, media code Product and emission amount 0,05 per unit for part XX-ECO-202.

Usage Emissions

Purpose: The purpose of this exercise is to register emissions that are generated when the part is used. You should also enter additional emission, i.e. emissions that are generated for example when the part is repaired.

Windows:
Part Eco-footprint

1. Register that the lifetime for part XX-ECO-100 is 100 000 h.
2. Click the Usage tab. On the Usage Emission tab, enter emission substance ENERGY, media code Waste and emission amount 0,02 per lifetime.
3. On the Additional Emission tab, enter emissions as described in the table below.

Calculate Eco-footprint for Manufactured Part

1. Open the Calculate Eco-footprint - Part dialog box and calculate emissions for the manufactured part XX-ECO-100.

Main Exercises

Purpose: The purpose of this lesson is to learn how analysis parts based on specific requirements for regulated substances.

Windows:
Requirements for Eco-footprint

Create an Analysis Based on Regulated Substances

1. Open the Requirements for Eco-footprint window.
2. Create a new record and enter; Requirement ID XX-ECO-1, Description equal to Regulations of Metals, set Phase in Date to today’s date, leave Phase out Date blank and set Req Valid Date one month in front in time, Save. Revision 1 of Requirement ID XX-ECO-1 is created in status Planned.
3. Click on the Regulated Substances tab.
4. Create two new records and use the list of value to select Substance No; PB (Lead) and CD (Cadmium).
5. For PB set Threshold W/W (%) equal to 0,0002 and for CD 0,0001.
   
   Note: Substances with no existing weight figures can be included in a requirement; the Threshold W/W (%) value can be set to zero.
    
6. Right-click from the header and select the option Set Status to Active.
7. Right-click again from the header and select the option Analyze. In the Analyze parts dialog enter Part No XX-ECO-100 and Select Struct Alt *. Secure that the analysis is performed for part Revision No 1 by entering an appropriate Effective Date. Press the OK button.
   
   Note: It is the Effective Date that controls which revision to base the calculations on, i.e. the revision valid for the entered Effective Date will be used for the calculation. This means that the calculation will blow through the entire structure and use the revision valid for the Effective Date for both the top part and the sub-assemblies. A specific Struct Alt and Rout Alt can be taken in to consideration in the calculation, but only for the top part not its sub-assemblies. When executing a calculation then is always Struct Alt * and Rout Alt * used for all sub-assemblies.
8. When the analyze back ground job is completed click on the Non Conforming Parts tab. The following parts should appear; XX-ECO-100 and XX-ECO-200. Study the calculated W/W (%) and compare with the Threshold W/W (%).
9. Click on the Non Conforming Top Parts tab. Part XX-ECO-100 should appear in the list, XX-ECO-200 is just a component included in XX-ECO-100 hence not a top part. Right-click from the line representing XX-ECO-100 and select the option Analyze Parts.
10. In the first section study which of the parts in the tree structure that has a calculated W/W exceeding the define Threshold W/W for any of the regulated substances. Review also the material declaration quality for each part in the tree structure. A part is only defined as passed if the calculated W/W is less than the define Threshold W/W and if the material declaration quality is ether Complete or Full. If these conditions aren’t fulfilled then is the part instead marked with a warning symbol in the tree structure. In the second section can you follow up information related to the substances for the non conformiong parts.

Create an Analysis Based on Criteria

1. Open the Requirments for Eco-footprint window.
2. Create a new record and enter; Requirement ID XX-ECO-2, Description equal to Regulations of Polybrom, set Phase in Date to today’s date, leave Phase out Date blank and set Req Valid Date one month in front in time, Save. Revision 1 of Requirement ID XX-ECO-2 is created in status Planned.
3. Click on the Regulated Substances tab.
4. Right-click and select the option Analyze on Criteria.
5. In the Analyze on Criteria dialog select the Hazardous Criteria Carcinogenic, press the OK Button.
6. All substances in the substance database defined as Carcinogenic will be added to the list of regulated substances.
   
   Note: If the analysis is started from this dialog then will then listed substances receive a Threshold W/W (%) value of zero. It is however optional to update the Threshold W/W (%) if requested.
    
7. Right-click from the header and select the option Set Status to Active.
8. Right-click again from the header and select the option Analyze.
9. In the Analyze parts dialog enter Part No XX-ECO-100 and Select Struct Alt *. Press the OK button.
   
   Note: It is the Effective Date that controls which revision to base the calculations on, i.e. the revision valid for the entered Effective Date will be used for the calculation. This means that the calculation will blow through the entire structure and use the revision valid for the Effective Date for both the top part and the sub-assemblies. A specific Struct Alt and Rout Alt can be taken in to consideration in the calculation, but only for the top part not its sub-assemblies. When executing a calculation then is always Struct Alt * and Rout Alt * used for all sub-assemblies.
    
10. When the analyze back ground job is completed click on the Non Conforming Parts tab. The following parts should appear; XX-ECO-100 and XX-ECO-201. XX-ECO-201 appears due to that it contains PBDE (Polybrominated Diphenyl Ethers) which is defined as defined as Carcinogenic.
