Service Overview
ESD Testing & Validation is the quantitative backbone of every compliant EPA. Propack performs on-site and laboratory testing of floors, worksurfaces, footwear, wrist straps, garments, packaging materials, and ionisers using instruments calibrated to NABL-traceable standards. Every test is performed per the relevant IEC 61340 or ANSI/ESD test method and reported with measurement values, acceptance criteria, and pass/fail status.
Testing services are available as standalone material qualification (e.g., validating a new flooring product before purchase), as part of an EPA commissioning programme (all elements tested on installation), or as periodic re-verification to maintain your S20.20 audit records. Results are delivered in a formal Test Report with instrument serial numbers, calibration dates, test conditions, and reference standards cited.
Test Capabilities
Flooring Resistance
Point-to-point and resistance-to-ground measurement per IEC 61340-4-1 using calibrated concentric ring probe and 9V/100V test voltages. Floor mapping across full facility footprint.
Worksurface & Seating
Resistance-to-groundable point measurement of workbenches, chairs, and shelving per ANSI/ESD S4.1 (surfaces) and ANSI/ESD STM12.1 (seating). Identifies inadequate bonding or degraded mats.
Personnel Grounding
Wrist strap system resistance (ANSI/ESD S1.1), footwear resistance (ANSI/ESD STM9.1), and combined person-to-groundable-point resistance. Body voltage generation and decay measurements.
Garment & Packaging Testing
Surface resistivity (IEC 61340-2-3), volume resistivity (IEC 61340-2-2), and ESD shielding (ANSI/ESD S11.4 for bags) of all ESD materials and packaging in use in the EPA.
Ioniser Qualification
Balance voltage and discharge time measurement per IEC 61340-2-1. Offset voltage trending, coverage mapping, and performance verification of benchtop, overhead, and room ionisers.
CDM & HBM Characterisation
ESD susceptibility assessment of your specific component or assembly — identifying the minimum voltage threshold at which damage occurs, guiding EPA design and process risk assessment.
Testing Process
- 1
Test Scope Definition
Agree on which elements require testing, the applicable test methods, acceptance criteria (S20.20 limits vs. customer-specific limits), and test location (on-site or send-to-lab).
- 2
Pre-Test Conditioning
Where required by the test method, materials are conditioned at controlled temperature and humidity (23°C ±1°C, 50% RH ±5%) for 24–72 hours before measurement.
- 3
Testing with Calibrated Instruments
All measurements performed with instruments calibrated within their valid NABL-traceable calibration period. Test conditions (ambient T°, RH) recorded at time of test.
- 4
Data Analysis & Reporting
Results analysed against acceptance criteria. Formal Test Report issued with measurement tables, pass/fail status, and recommendation for any marginal or failed items.
- 5
Report Issuance
Signed Test Report issued within 5 business days of testing completion. Suitable for inclusion in your ESD Control Plan records and S20.20 certification audit file.
