Overview
ASTM D5077-90(2021) - Standard Terminology Relating to Electrostatic Discharge (ESD) Packaging Materials is a key international reference for professionals involved in ESD protection and packaging. Developed by ASTM International, this standard provides clear definitions and consistent terminology for materials and processes related to electrostatic discharge (ESD) protection. By establishing a common language, it supports effective communication within the electronics, packaging, and distribution industries, and aligns with internationally recognized principles for standardization as endorsed by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Key Topics
The standard covers a wide range of essential terminology relevant to the selection, specification, and use of ESD packaging and protective materials. Important topics include:
- Electrostatic Discharge (ESD): Clarity on terms surrounding the transfer of electrostatic charge between bodies of different potentials.
- Antistatic Agents and Properties: Definitions of antistatic characteristics and their distinction from other electrical properties such as resistivity.
- Material Resistivity: Explanation of surface resistivity and volume resistivity, key for classifying ESD protection materials.
- Conductors, Insulators, and Grounding: Descriptions of materials based on their electrical conductivity and the concept of grounding for static control.
- Protective Functions: Differentiation between ESD-protective materials, electromagnetic shields, and electrostatic shields.
- Sensitive Items: Identification of ESD-sensitive (ESDS) items and the importance of proper packaging and handling measures.
- Ionization: Overview of the ionization process relevant to ESD control environments.
This terminology forms the foundation for specifying packaging materials that prevent damage from unwanted static electricity during manufacturing, storage, and transport.
Applications
The standardized definitions in ASTM D5077-90(2021) are directly applicable across various sectors that handle electrostatic-sensitive items:
- Electronics Manufacturing and Assembly: Facilitates the design and selection of proper ESD packaging to protect circuitry, components, and finished products from ESD events.
- Supply Chain and Distribution: Ensures correct packaging and handling methods are specified and communicated throughout the logistics process for ESD-sensitive goods.
- Quality Assurance and Compliance: Supports compliance with ESD control programs and industry best practices as required by global supply chains.
- Procurement: Aids buyers and suppliers in specifying, sourcing, and verifying packaging and protective materials in line with recognized terminology.
- Training and Education: Provides a foundation for onboarding and educating staff on ESD control principles and material selection.
By referencing this standard, organizations can reduce confusion, minimize the risk of ESD damage, and align their practices with global trade requirements.
Related Standards
ASTM D5077-90(2021) references and complements several related standards, reinforcing its role in the ESD protection ecosystem:
- ASTM D996 - Terminology of Packaging and Distribution Environments: Offers additional terminology pertinent to packaging and shipping environments.
- EIA-541 - Packaging Material Standards for ESD Sensitive Items: Provides material standards specifically for packaging ESD-sensitive products.
Organizations aiming for comprehensive ESD control should consider using these standards together to achieve consistent terminology, reliable packaging performance, and international compliance.
