How to create Certificate of Analysis for outgoing Quality Process

Certificate of Analysis or CoA is a report stating all criteria is met by supplier as agreed by customers during initial product review. Once customers has outlined what they need, suppliers will perform test to ensure product is conform to its fit and function.

CoA is tedious but necessary.

A generic CoA Template typically includes:

- Customer name

- Customers part #

- Customer PO#

- Supplier part#

- Supplier PO#

- Lot#

Report of analysis will include the following:

1. Performance data may include:
- max,
- min and
- average.
This includes stress test, air flow, density, tensile strength or anything required by customer. Be sure to check all units are accurate. It’s also best practice to include specifications on each required measurements.

2. Another information that might be critical is the part dimensions such as thickness, width, profiles, depth etc.

Last but not least is to ensure validity of the certificate. Report must be signed by qualified Quality personnel, preferably using an electronic signature. Copy must be sent using pdf format if send via email.
