ANSI/ESD S20.20 Certification: Requirements, Audit Process and Cost for Electronics Makers
Electrostatic discharge damages electronic components every day, often without any visible sign. A part that is weakened by ESD may pass final test and fail in the field. That is why many global customers now ask their suppliers for ANSI/ESD S20.20 certification.
In short: ANSI/ESD S20.20 is the standard for an ESD control programme. To get certified, you write an ESD control plan, set up ESD Protected Areas (EPAs), train staff, verify equipment regularly and pass an audit by a certification body recognised under the ESD Association's programme.
What ANSI/ESD S20.20 Covers
The standard has two kinds of requirements:
- Administrative: ESD control programme plan, training plan, product qualification and compliance verification plan
- Technical: grounding and bonding, personnel grounding, EPA requirements, packaging and marking
The current version is designed to protect devices sensitive down to 100 V Human Body Model, 200 V Charged Device Model and 35 V on isolated conductors. If your products include more sensitive parts, the plan must add extra controls.
Key Requirements
1. ESD control programme plan
A written plan covering scope, roles, required ESD items, test methods and limits. It should match how your factory actually works.
2. Training plan
Initial training for everyone who handles ESD-sensitive items, before they handle them, and recurrent training at set intervals. Keep records for each person.
3. Compliance verification plan
How often each ESD control item is checked and against which limits: wrist straps, footwear, work surfaces, floors, ionisers, seating and carts.
4. Grounding and bonding
A grounding system that connects all conductors, including people, to a common ground point.
5. Personnel grounding
Wrist straps for seated work and footwear with ESD flooring for standing or moving work, with daily checks at entry.
6. ESD Protected Areas
Marked areas with access control, grounded surfaces and control of insulators. Ionisers are used where insulators cannot be removed.
7. Packaging and marking
Packaging that protects items when they leave the EPA, as defined in your packaging plan and customer contracts, and correct ESD marking on packages.
Certification Process
- Gap analysis: compare your current controls with the standard.
- Write the plans: programme, training and compliance verification.
- Set up EPAs: install grounding, flooring, workstations and test equipment.
- Train staff and keep records.
- Run compliance checks for a few months to build records.
- Internal audit and management review, with corrective actions.
- Certification audit by a recognised certification body.
- Surveillance audits during the cycle, then recertification.
Cost and Timeline
The main costs are:
- Infrastructure: ESD flooring, grounded workstations, wrist strap and footwear testers, ionisers, ESD packaging
- Test equipment for compliance verification
- Training for staff and internal auditors
- Certification body fees for the audit and surveillance, which depend on site size
A factory that already has good ESD controls may need only documentation and records. A new site has to budget for infrastructure. For time, three to six months from start to certification is common.
Common Audit Findings
- Plans that describe procedures the factory does not follow
- Missing or overdue compliance verification records
- Insulators such as plastic folders and bottles inside the EPA
- Staff handling ESD items without recurrent training
- No daily check records for wrist straps and footwear
How Instacertify Helps
We run the gap analysis, write the ESD plans, train staff and internal auditors, run a pre-audit and coordinate the certification audit. See our ANSI/ESD S20.20 certification service.
Frequently asked questions
What is ANSI/ESD S20.20?
It is the ESD Association standard for developing an electrostatic discharge control programme. It sets the administrative and technical requirements for protecting electronic parts, assemblies and equipment from ESD damage.
Is ESD S20.20 certification mandatory?
No law requires it, but many electronics, automotive, aerospace and defence customers require suppliers to be S20.20 certified or compliant before they will place orders.
What is an EPA?
An ESD Protected Area is a defined area where ESD-sensitive items are handled, with grounded work surfaces, flooring, personnel grounding, ionisers where needed and controlled access.
What training is required for ESD S20.20?
Everyone who handles or may touch ESD-sensitive items must receive initial training before handling them and recurrent training at intervals defined in the training plan. Records of training must be kept.
How long does ESD S20.20 certification take?
For a site starting from scratch, three to six months is common to set up the programme, train staff and run internal audits before the certification audit.
Is ESD S20.20 certification valid for life?
No. Certification is maintained through regular surveillance audits and a recertification audit at the end of each certification cycle.
