Qualifying the SCS 81705 Series anti-static shield bags to military standards
There are a few, sometimes complicated steps to go through before your product can qualify for a particular military specification. SCS recently introduced their new 81705 Series static shield bags and film qualified to MIL-PRF-81705E Type III, Class 2. The qualification didn’t happen overnight and the process can be quite involved including the required, very specific markings on the bags and film.
What makes these SCS 81705 Series anti-static shield bags so special?
First, they meet MIL-PRF-81705E Type III, Class 2 qualifications, frequently linked to higher-level assembly protection such as in military, medical and aerospace markets. Each SCS 81705 bag contains four layers of protection – static dissipative coating, polyester, metal and polyethylene laminate. The polyester dielectric works with the metal layer to create discharge shielding. The static dissipative outside wall allows electrostatic charges to be removed when grounded.
Qualification military specification (MIL-Spec) basics
1. What are the United States defense standards?
They’re often referred to as military standard (MIL-STD) or military specification (MIL-SPEC), and they help meet the standardization objectives set by the U.S. Department of Defense. The defense standards may also be used by other non-defense government organizations (NGOs), technical organizations and industry.
2. How do I apply for qualification?
You apply in writing and each application contains the number and date of the specification, desired testing, as well as the type, grade, class, or other specification designation of the product. The application also includes the brand designation for the product and where the product was manufactured. If you’re a distributor, you’ll also receive a CAGE code.
Example – MIL-PRF-81705E Type III, Class 2 – MIL (military) PRF (document Id/Performance), 81705E (document number), Type III (document type), Class 2 (document class)
3. What is the QPL?
The qualified products list (QPL) is a listing in the qualified products database (QPD) of items successfully subjected to a defined set of qualification and periodic tests using processes, worst case designs or materials to verify the end product’s design, performance, quality, and reliability.
4. What do the general DOD qualification steps look like?
5. Where can I get the required MIL-Spec testing done for qualifying my product?
You can have testing done in a laboratory operated by or under contract to the government, or a laboratory used by the manufacturer or distributor either in the plant or one that’s under contract.
6. Where do I find my product listed once I’m qualified?
Once a product meets the recognized qualification requirements, the product will be listed online in the Qualified Products Database (QPD). The QPD can be accessed through the acquisition streamlining and standardization information system (ASSIST).
7. What does a qualification not do?
A qualification does not –
• Relieve the supplier of his contractual obligation to deliver items meeting all specification requirements.
• Guarantee acceptability under a contract
• Waive any requirements for inspections or for maintaining quality control measures satisfactory to the Government
• Relieve the original equipment manufacturer of contractual obligations to ensure that delivered items (including the qualified items used in the equipment) comply with all specification requirements
