The number of regulated substances increases every 6 months. If you make Regulatory Compliance Declarations (RCD), you need to check the new regulated substances and update your RCDs every six months. If you make Full Materials Declarations, BOMcheck does the work for you and checks the new regulated substances every 6 months. You can make a Full Material Declaration (FMD) for one part or for a list of parts. For example, a product family of ceramic capacitors contains a large number of part numbers (e.g. for different values of capacitance), but all of the part numbers are manufactured using the same set of materials and substances. You can make one FMD for the parts list by providing the worst case percentage weight of each material in the part and the worst case percentage weight of each substance in each material. BOMcheck will apply these percentages to the weight of each part in your list to calculate the amount of the materials and the substances in each part.

Creating a Full Material Declaration for a list of part numbers is an 8 step process:

1. Create your parts list in Excel by including the part number in column 1, the part name in column 2 and the part weight in column 3. Do not include a header or title row and do not include data in any other columns. Save your file as a Unicode text file.

2. Login to www.BOMcheck.net and select 'Enter Data' and then select 'Add Declaration' and you will see the tool to make a Full Material Declaration. Select 'Browse' to attach the list of part numbers, part names and part weights and then use the drop-down boxes to specify the unit of weight (kg, gm, mg or µg) and the material unit (each, centimeter, meter, square centimeter, square meter, cubic centimeter, liter or cubic meter).

3. Enter the percentage weight of each material in the part and the percentage weight of each substance in each material.

4. Attach PDF evidence documents (e.g. RoHS test certificates if available) to support your declaration, if necessary.

5. Enter the date that the declaration is valid from. This can be a date in the past if the declaration has been valid for some time.

6. Type in the title of the parts list which is attached to the declaration (e.g. ceramic capacitors). The declaration title will help you to locate your parts list in your Account Overview screen if you need to change or update the declaration details for your parts list in the future.

7. Decide who can view your FMDs, and who can view the RCDs which BOMcheck calculates for you.

8. Preview the declaration, approve it and then sign it with your electronic signature by typing in your password.

Congratulations! Your FMD is published and BOMcheck has calculated an RCD from your FMD data. BOMcheck will use your FMD data to calculate a new RCD every 6 months when new substances become regulated.
