Toxic Gas Emission Measurement during Apparel Combustion
The measurement of toxic gas emissions during apparel combustion is a critical process in ensuring public safety and compliance with international regulations. This service involves the rigorous testing of textiles and apparels to assess their flammability characteristics, focusing specifically on the release of toxic gases such as carbon monoxide (CO), nitrogen oxides (NOx), hydrogen cyanide (HCN), and other harmful compounds.
The importance of this service cannot be overstated. As textile and apparel manufacturers strive for innovation in design and materials, it is essential to ensure that these advancements do not compromise public safety. The process involves the following steps:
- Selection of representative samples from different batches and production lines
- Preparation of specimens according to specific protocols ensuring consistency across tests
- Subjecting the specimens to controlled combustion conditions in a calorimeter or similar apparatus
- Monitoring the release of gases using sensitive analytical instruments such as gas chromatography, Fourier transform infrared spectroscopy (FTIR), and mass spectrometry
- Data analysis and comparison against established standards for acceptable emissions levels
The testing process is conducted in accordance with international standards including ISO 13962-1 and ASTM E659, which provide guidelines on the procedure for measuring toxic gas emissions during textile combustion. These standards ensure that the testing methodology is consistent and reproducible.
Accurate measurement of these gases is crucial as they can have severe health implications when inhaled. Therefore, this service not only aids manufacturers in meeting regulatory requirements but also helps them improve product safety by identifying potential hazards early in the design process.
| Key Parameters | Description | Acceptance Criteria |
|---|---|---|
| Carbon Monoxide (CO) | A colorless and odorless gas formed during incomplete combustion of carbon-containing materials. | <50 ppm as per ISO 13962-1 |
| Nitrogen Oxides (NOx) | Group of compounds primarily composed of nitrogen and oxygen that contribute to air pollution. | <200 ppm as per ASTM E659 |
| Hydrogen Cyanide (HCN) | A highly toxic, flammable gas used in the production of various chemicals and pesticides. | <1 ppm as per EN 478-2 |
