JIS K7122 Thermogravimetric Analysis of Plastics
The JIS K7122 test procedure is a standardized method used to measure the thermal stability and mass loss characteristics of plastics. This thermogravimetric analysis (TGA) technique is essential for quality managers, compliance officers, R&D engineers, and procurement specialists who need accurate data on how plastics behave under heat.
The JIS K7122 standard specifies a range of temperatures where the sample’s mass changes due to decomposition or evaporation. This information can be critical in selecting materials that meet specific performance criteria such as high-temperature resistance, chemical stability, and durability across various applications including automotive parts, electronics enclosures, and medical devices.
The test involves heating a precisely weighed sample at a constant rate of temperature increase while monitoring the change in mass. By analyzing the weight loss versus temperature data, engineers can identify key properties like thermal stability, decomposition temperatures (Td), and residual carbon content after complete pyrolysis.
The JIS K7122 method is particularly useful for comparing different grades of plastic or assessing the impact of additives on a polymer’s thermal behavior. This information can guide material selection processes to ensure that materials not only meet regulatory requirements but also perform reliably in end-use conditions.
Compliance officers rely heavily on this test to ensure their products comply with international standards, such as JIS K7122 itself and other relevant regulations like ISO 13584 or ASTM D5460. Understanding the thermal stability of plastics is crucial for ensuring long-term performance in demanding environments.
For R&D engineers, this test provides insights into how new formulations might behave under different temperature conditions. It helps them optimize formulations to achieve desired properties without compromising on safety and durability.
Incorporating JIS K7122 results into the procurement process ensures that suppliers deliver materials that meet stringent quality expectations. This aligns production with corporate goals for sustainability, reliability, and regulatory compliance.
Scope and Methodology
The scope of JIS K7122 thermogravimetric analysis encompasses the determination of thermal stability and mass loss behavior of plastics. The methodology involves heating a sample at a controlled rate, typically 5°C/min to 10°C/min, in an inert atmosphere such as nitrogen or argon.
| Test Parameters | Description |
|---|---|
| Temperature Range | The test is conducted over a wide range of temperatures depending on the sample characteristics. Typically, it starts from room temperature up to 1000°C or even higher. |
| Inert Atmosphere | The analysis takes place in an inert atmosphere to avoid reactions with air that could affect results. |
| Sample Size and Preparation | A precise mass of the sample is required, usually ranging from 5 mg to 20 mg, depending on the expected weight loss. Samples are prepared according to the standard specifications. |
| Data Collection | The system records mass versus temperature data continuously during heating. |
| Analysis of Results | The results include the onset temperature (Tonset) at which weight loss begins, the decomposition temperature (Td) where 50% weight loss occurs, and total mass loss (%). |
