ISO 17299-2: Verified Odor Control Performance

 

What is ISO 17299-2?

 

ISO 17299-2 is an internationally recognized standard that evaluates the deodorant performance of textile materials using a detector tube method. This method quantifies how effectively a fabric reduces specific odor-causing gases under controlled conditions.

At UltraZeo, we use ISO 17299-2 to validate the odor-neutralizing capabilities of treated textiles, to help ensure consistent, measurable performance for your end-use applications.

 How the Test Works

The ISO 17299-2 method involves a semi-quantitative analysis using colorimetric gas detector tubes.

1. Preparation of Odorant Gases

• A known concentration of target odorants- such as ammonia, is introduced into a sealed test chamber.

2. Sample Conditioning

• Textile specimens are pre-conditioned to standard atmospheric conditions to ensure test consistency.

3. Exposure Phase

• The fabric is exposed to the odorant gas in a controlled environment for a defined period.

4. Measurement

• After exposure, the remaining gas concentration is measured using detector tubes, which change color based on gas concentration.

5. Performance Calculation

• The odor reduction rate is calculated using a specific formula.

Why it Matters for Your Products:

-Reliable Performance Benchmark

ISO 17299-2 provides a standardized, reproducible method to compare deodorizing activity across different fabrics or treatments. 

-Scalable

Ideal for routine quality control, product development and batch validation without the need for complex instrumentation.

 

ISO 17299-3: Advanced Odor Control Validation with Gas Chromatography

What is ISO 17299-3?

ISO 17299-3 is a globally standardized method for quantitatively evaluating the deodorant performance of textiles using gas chromotography (GC). This method is designed for high-precision analysis of how effectively a fabric reduces specific odor-causing compounds under controlled lab conditions.

 How the Test Works

ISO 17299-3 is method involves a multi-step analytical process using gas chromotography to measure the concentration of odorants before and after exposure to the textile sample:

1. Preparation of Odorant Gases:

A defined concentration of target odorants such as indole, isovaleric acid, or acetic acid is introduced into a sealed test chamber.

2. Sample Conditioning

• Textile specimens are conditioned under standardized temperature and humidity to ensure reproducibility.

3. Exposure Phase

• The fabric is exposed to the odorant gas mixture got a fixed duration in a controlled environment. 

4. Air Sampling

• After exposure, the surrounding air is collected and analyzed using gas chromotography to determine the residual concentration of each deodorant. 

5. Performance Calculation

• The odor reduction rate (ORR) is calculated using a specific formula.

Why it Matters for Your Products:

-Quantitative, High Resolution Data

ISO 17299-3 provides precise, reproducible measurements of deodorizing performance, ideal for high-performance and regulatory sensitve applications.

-Supports Certification and Compliance

This method is often required for third-party validation, product certification, and international regulatory submissions.

-Ideal for Advanced Product Development

Enables detailed evaluation of fiber-level treatments, coatings and functional finishes across a wide range of textile formats.

-Applicable to complex Odor Profiles

Suitable for testing against low-threshold, persistent odorants that are difficult to measure with simpler methods.
