Understanding ESD documents and ESD Standards required in ESD Control program.
An ESD Coordinator plays a big role when it comes to establish an ESD Control program for his or her organization. The ESD Coordinator must be well equipped with ESD knowledge and know how before he or she can carry his or her duties well. One of the things that the ESD Coordinator must know is to understand the ESD documents and ESD standards before setting up the ESD Control program.
The ESD documents can be typically classified into four categories such as:
•Standard
•Standard Test Method
•Standard Practice
•Technical report
Standards are ESD document that specify ESD requirements to be met by an ESD product, ESD material, system and process which are required in establishing an ESD Control program. ESD Standard begins with a prefix S such as the following:
ANSI/ESD S1.1: Wrist strap
ANSI/ESD S4.1: Work surfaces - Resistance measurements
ANSI/ESD S6.1: Grounding
ANSI/ESD S8.1: ESD awareness symbols
ANSI/ESD S20.20: Standard for the development of an ESD control program
ANSI/ESD S541: Packaging materials for ESD sensitive items
ANSI/ESD S7.1: Floor material – Characterization of materials
Standard Test Methods are ESD document that specify standardized test method which produce reproducible test results for evaluating an ESD product, ESD material, system and process that are required in establishing an ESD Control program. ESD Standard Test Method begins with a prefix STM as the followings:
ANSI/ESD STM2.1: ESD garments
ANSI/ESD STM3.1: Ionization
ANSI/ESD STM4.2: ESD Protective Work surfaces - Charge dissipation characteristics
ANSI/ESD STM5.1: Electrostatic discharge sensitivity testing - Human body model – Component level
ANSI/ESD STM5.2: Electrostatic discharge sensitivity testing - Machine model – Component level
ANSI/ESD STM5.3.1: Electrostatic discharge sensitivity testing - Charged device model (CDM)—Component level.
ANSI/ESD STM9.1: Resistive characterization of footwear (exclude heel strap and toe Grounders)
ANSI/ESD STM11.11: Surface resistance measurement of static dissipative planar materials
ANSI/ESD STM11.12: Volume resistance measurement of static dissipative planar materials
ANSI/ESD STM 11.13: Two point resistance measurement
ANSI/ESD STM11.31: Evaluating the performance of electrostatic discharge shielding bags
ANSI/ESD STM12.1: Seating - Resistive characterization
ANSI/ESD STM13.1: Measuring electrical potential from electrical soldering/desoldering hand tools
ANSI/ESD STM97.1: Floor materials and footwear – Resistance measurement in combination with a person
ANSI/ESD STM97.2: Floor materials and footwear - Voltage measurement in combination with a person
When the test method does not have the capability to produce reproducible test results, the ESD document is then classified as Standard Practice and this ESD Standard Practice begins with a prefix SP as the following:
ESD SP3.3: Periodic verification of air ionizers
ESD SP9.2: Foot grounders - Resistive characterization (exclude static control shoes)
ESD SP10.1: Automated handling equipment (AHE)
ESD SP14.1: System level Electrostatic Discharge simulator verification standard practice
ESD SP5.4: Latch up sensitivity testing of CMOS/BiCMOS Integrated Circuits and Transient Latch up testing – component level supply transient stimulation
ESD SP5.5.1: Electrostatic Discharge sensitivity testing Transmission Line Pulse (TLP) - Component level
ESD SP5.3.2: Sensitivity testing Socketed Device model (SDM) – Component level
ESD SP15.1: In use resistance testing of gloves and finger cots
Technical reports are ESD reports that provide technical and informational reference on a specific ESD material, product, system or process. This ESD reports begin with a prefix TR as following:
ESD TR 20.20: Handbook for the development of an ESD Control Program
ESD TR53: Compliance Verification of ESD Protective equipment and materials
ESD TR50.0.01: Can Static Electricity Be Measured
ESD TR50.0-02: High Resistance Ohmmeters–Voltage Measurements

ESD TR10.0-01: Measurement and ESD Control Issues for Automated Equipment Handling of ESD Sensitive Devices below 100 Volts
ESD TR4.0-01: Survey of Work surfaces and Grounding Mechanisms
ESD TR50.0-03: Voltage and Energy Susceptible Device Concepts, Including Latency Considerations
ESD TR3.0-02: Selection and Acceptance of Air Ionizers
Although there are many ESD documents available, only a handful of ESD documents that are required by a NEW ESD Coordinator to help him or her ESD in establishing the ESD Control program.

An ESD Coordinator is encouraged to keep reading, evaluating and experimenting so as to improve his or knowledge. Keeping abreast with ESD technology that keeps changing is a must for the ESD Coordinator to ensure the ESD Control program is still functioning as requested over the years.
