Introduction

Choosing the right ESD garments for cleanroom environments is not only about comfort or appearance—it directly affects product quality, yield, and ESD compliance.

This guide explains the key factors engineers and procurement teams should consider when selecting ESD garments for cleanroom applications.

1. Understand Your Cleanroom Classification

Before selecting ESD garments, identify your cleanroom level:

• ISO Class 5–6: Semiconductor, advanced electronics

• ISO Class 7–8: Electronics assembly, medical devices

Higher cleanroom classes require:

• Lower particle shedding

• Better fabric stability

• Stricter garment construction

2. Fabric Selection: The Core of ESD Performance

High-quality ESD garments typically use:

• Polyester filament fabric

• Carbon or conductive yarn woven in grid or stripe patterns

Key fabric requirements:

• Stable surface resistance

• Low lint generation

• Resistance to repeated laundering

⚠️ Avoid generic “anti-static” fabrics without verified test data.

3. ESD Performance Requirements

For most cleanroom applications:

• Surface resistance should be ≤ 1 × 10¹¹ ohms

• Performance should be verified according to IEC 61340 standards

Consistency across batches is critical for long-term compliance.

4. Garment Design & Coverage

Effective ESD garments must:

• Fully cover personal clothing

• Include long sleeves

• Have secure closures (zipper, snaps)

Open or short-sleeved garments significantly reduce ESD protection.

5. Compatibility with ESD Control Systems

ESD garments must work as part of a system:

• Wrist straps

• Footwear / flooring

• Grounded workstations

Garments alone cannot eliminate ESD risk.

6. Laundering & Maintenance

Choose garments designed for:

• Industrial laundering

• Stable ESD performance after washing

• Clear wash-cycle limits

Improper washing is a common cause of ESD failure.

Conclusion

Selecting ESD garments for cleanrooms requires balancing ESD performance, cleanroom compatibility, and durability. A structured selection process reduces risk and ensures long-term compliance.
