Introduction

Surface Resistivity Testing As per IS 3396

Understanding Surface Resistivity

Surface resistivity is a measure of how well a material resists electrical current flowing across its surface. The results are typically expressed in ohms per square (Ω/□) and help classify materials into:

  • Insulative materials (≥ 10¹² Ω/□)

  • Static dissipative materials (10⁵ to 10¹¹ Ω/□)

  • Conductive materials (≤ 10⁴ Ω/□)

These values are crucial in preventing electrostatic discharge (ESD), which can damage sensitive components in electronics and create safety hazards.


📘 What Does IS 3396 Define?

IS 3396, established by the Bureau of Indian Standards (BIS), outlines the method for determining surface resistivity in solid electrical insulating materials, primarily those made of plastic, rubber, or polymer composites.

It includes guidelines for:

  • Sample preparation

  • Test electrode configuration

  • Voltage application

  • Environmental controls such as humidity and temperature

At Kiyo, we strictly follow these parameters to ensure repeatable and compliant test results.


🧪 Industries That Rely on Surface Resistivity Testing

Surface resistivity testing is indispensable for several applications, including:

  • Electronics manufacturing – for PCBs, connectors, and enclosures

  • Automotive interiors – ensuring safety from static shocks

  • Packaging materials – especially for ESD-sensitive components

  • Flooring and mats – in cleanrooms and control panels

  • Defense equipment – where insulation properties are mission-critical

FAQ

1. How is the test conducted?

A voltage is applied across electrodes placed on the material's surface in a controlled environment. The resulting current is measured to calculate resistivity.

2. What are the test conditions specified by IS 3396?

IS 3396 specifies environmental controls (like humidity and temperature), electrode configuration, sample conditioning, and test voltage to ensure consistency.

3. What is the measurement unit used?

Surface resistivity is measured in ohms per square (Ω/□), indicating resistance across a unit square of the material surface.

Introduction

Specimen Preparation in Chennai

Why Accurate Specimen Preparation Matters

Before any ASTM or ISO test is conducted, the material must be shaped, notched, or molded to precise specifications. Errors in thickness, notch depth, or surface finish can cause:

  • Test failures

  • Data variability

  • Rejection in quality audits

That’s why Kiyo R&D Center & Laboratory prioritizes dimensional accuracy, standard compliance, and repeatability in every specimen prepared.
