ESD-Safe Cleanroom Coveralls are Designed for Use in Controlled Environments When Static Control is Paramount.

Cleanrooms, typically utilized for scientific research or specialized industrial production, require specific PPE that limits contamination and provides multi-faceted protection.  Transforming Technologies TX4000 ESD Cleanroom Garment System protects the environment from the number one source of contamination and static found in cleanrooms – people. Electrostatic charge is an invisible contaminant and has the potential to degrade or destroy both product and equipment, as well as attract unwanted particles. Controlling these charges with the TX4000 Garment System throughout the controlled environment is essential to a productive manufacturing process.

Static Control From Hood-To Boot

Typcial ESD-Safe Cleanroom Garments use a static dissipative fabric, but little concern is made with the electrical continuity between fabric panels and the components such as the hood, or boots.  Due to the lack of continuity, a static charge originating on the hood may not be able to dissipate through the coverall and boot to be eliminated via the grounded floor.   This is referred to as a isolated conductor

TX4000 solves this issue. Groundable from hood-to-boot, the TX4000 ESD Cleanroom Garment System is made with a reliable ISO 6 static dissipative fabric with each component—hood, coverall, boots—electrically connected with conductive threads and  ground snaps.  A superior conductive sole on the boot eliminates static on the personnel through the ESD floor or mat quickly and safely. The garments system’s superior workmanship and reliable panel-to-panel continuity makes it compliant with IEST-RP-CC052 and ANSI ESDS.2020 standards. The TX4000 Garment System maintains consistent continuity readings for up to 100 wash cycles

Transforming Technologies TX4000 has a selection of washable boots, all of which are ideal for cleanrooms, labs, manufacturing facilities, and other sterile environments. The washable boots help protect the integrity of cleanroom environments. Because they’re reusable, the boots can also save you time and money.  Choose from ESD Soft Sole, ESD Hard Sole and Non-ESD Hypalon Boots.

The TX4000 Systems complies with ANSI ESDS20.20 & IEST-RP-CC052.1 standards and qualifies as a Category 3 cleanroom ESD garment capable of grounding mobile operators with both soft and hard sole boots.​ The most effective way to determine the effectiveness of a grounding system for personnel is to measure the voltage on a person while moving.  If ungrounded, just moving throughout the cleanroom can generate a charge on the body high enough to damage electronics components nearby. The TX4000 is designed to ground a person when standing on an ESD floor without having to tether themselves with a wrist strap. It is one less precaution to be concerned with while working in sensitive applications.

IEST Standards

IEST-RP-CC052.1 – Understanding, Identifying and Controlling Electrostatic Charge in Cleanrooms and Other Controlled Environments: This Recommended Practice (RP) provides a basis for understanding how electrostatic charge occurs. This RP discusses problems caused by electrostatic charge in cleanrooms, as related to particle management, physical damage from discharge and process interruptions from transient electromagnetic interference (EMI). This RP also provides suggestions for identifying and resolving such risks by means such as dissipation of charge from conductors and process-essential insulators that have an opportunity to interact with ESD sensitive (ESDS) items. Such conductors include personnel, conductive components in production equipment and associated fixtures.

ANSI/ESD S20.20 Standards

ANSI/ESD STM97.2 – Walking Test:  The most effective way to determine the effectiveness of a grounding system for personnel is to measure the voltage on a person while moving.   ANSI/ESD STM97.2 describes the equipment needed and the procedure for measuring voltage on a person.   The voltage measured can be compared to the upper limit that can be tolerated in the process.

ANSI/ESD STM 2.1 – Resistance to Ground:  The electrical resistance from any point on the person/garment to a verified electrical ground source (Typically third wire AC ground).  A lower resistance allows voltage to flow from the person and garment to ground, whereas a higher resistance traps the voltage on the person possibly leading to particle attraction or a voltage discharge to sensitive devices.   ANSI/ESD STM 2.1 provides a method to verify the resistance to ground of a groundable garment system
