What Are the ASTM and ISO Standards for Water Vapor Transmission Rate Tester in Vietnam


Introduction: Why WVTR Testing Matters in Vietnam’s Evolving Industry

Vietnam’s manufacturing and packaging industries have experienced rapid growth over the past decade, driven by exports in food, pharmaceuticals, and electronics. With this expansion comes a greater need for accurate material barrier testing:- specifically Water Vapor Transmission Rate (WVTR) testing.

A Water Vapor Transmission Rate Tester in Vietnam helps manufacturers measure how much water vapor passes through a material over a specific time. This data is vital for evaluating the protective quality of films, laminates, and packaging materials that guard against moisture damage.

From pharmaceutical blister packs to flexible food pouches, WVTR testing ensures long shelf life, stability, and compliance with ASTM and ISO international standards:- establishing confidence in both domestic and export markets.

Understanding WVTR: The Core Concept

The Water Vapor Transmission Rate (WVTR) quantifies how much moisture vapor permeates a material under controlled temperature and humidity conditions. This is expressed in grams per square meter per 24 hours (g/m²·24h).

Testing is performed using high-precision instruments like the packaging testing equipment TT-WVTR200 Infrared Method Water Vapor Transmission Rate Tester, which detects vapor flow and transmittance through materials such as plastic films, metal foils, paper composites, and medical packaging.

ASTM and ISO Standards for WVTR Testing

a) ASTM F1249: Infrared Detection Method

This is the most widely recognized international standard for Water Vapor Transmission Rate testing equipment. It specifies procedures for determining WVTR using an infrared sensor technique.

  • Scope: Used for flexible barrier films, laminates, and sheet materials.

  • Principle: Measures moisture transmission by detecting the infrared absorption of water vapor carried by dry nitrogen gas.

  • Advantages: High precision, short test duration, and reproducibility.

Testron’s TT-WVTR200 Infrared Method Water Vapor Transmission Rate Tester fully complies with ASTM F1249, offering superior infrared sensitivity up to 0.0001 g/(m²·24h).

b) ISO 15106-2: Differential Pressure Infrared Method

BS EN ISO 15106-2 outlines international procedures similar to ASTM F1249, focusing on infrared detection under controlled environmental conditions.

  • Scope: Applicable for plastic films, laminates, and high-barrier materials.

  • Key Metric: Temperature and humidity control accuracy within ±0.1°C and ±2%RH.

  • Significance: Ensures consistency across laboratories worldwide, enabling Vietnamese manufacturers to meet export testing standards for Europe and Asia-Pacific.

Testron designs each Water Vapor Transmission Rate Tester analyzer to align seamlessly with ISO and EN protocols, ensuring global test comparability.

c) Additional Recognized Standards

  • JIS K7129 (Japan): Measures WVTR for packaging materials using infrared sensors.

  • GB/T 26253 (China): Defines national-level specifications for WVTR measurement and calibration procedures.

  • YBB 00092003 (Pharma): Standard for pharmaceutical packaging testing, ensuring data integrity and material suitability for drugs.

The TT-WVTR200 Water Vapor Transmission Rate Test System supports all these standards, making it one of the most versatile instruments for multi-regulatory environments.

How the TT-WVTR200 Infrared Method WVTR Tester Works

The TT-WVTR200 Infrared Method Water Vapor Transmission Rate Tester uses a differential humidity technique to measure the vapor passing through a test specimen.

Testing Process:

  1. The sample is clamped between two chambers:- one with high humidity and one with dry nitrogen gas.

  2. Due to the humidity gradient, moisture travels through the material.

  3. The dry nitrogen carries the transmitted vapor to an infrared sensor.

  4. The Water Vapor Transmission Rate Tester analyzer converts the signal into quantitative data, displaying results in real time.

This system enables accurate measurement of samples with different barrier properties:- ranging from 0.002 to 200 g/(m²·24h).

Technical Highlights of Testron TT-WVTR200

  • Resolution: 0.0001 g/(m²·24h) – exceptional sensitivity for low barrier films.

  • Temperature Accuracy: ±0.1°C using semiconductor stabilizers.

  • Humidity Precision: ±2%RH, ensuring stable environmental conditions.

  • Real-Time Curves: Displays time-dependent data for humidity, temperature, voltage, and flow.

  • Ease of Operation: One-button test automation with intelligent control.

  • Compliance: Fully compatible with ASTM F1249 and ISO 15106-2.

This makes Testron’s model the most trusted Water Vapor Transmission Rate Tester manufacturer solution for packaging and polymer research laboratories in Vietnam.
