CSA D6413 Vertical flame resistance of fabrics Standard method
The Canadian Standards Association (CSA) standard D6413 specifies the vertical flame resistance test for fabrics. This method evaluates how well a fabric resists ignition and continues to burn when exposed to an open flame. It is particularly important in industries where textiles come into direct contact with open flames or high heat, such as those involved in manufacturing clothing, upholstery, and industrial protective gear.
The test setup involves positioning the specimen vertically between two metal plates, which are then exposed to a standard flame for a specified duration. The flame is applied at a controlled height above the fabric, and the time taken for the fabric to ignite and burn away from the point of application is measured. This measurement provides critical data on the fabric's resistance to ignition.
The test procedure is designed to simulate real-world scenarios where fabrics might be exposed to open flames or hot surfaces. The standard method ensures that textiles meet safety requirements, thereby protecting users from potential fire hazards. Compliance with this standard is essential for manufacturers who want their products to pass rigorous quality control checks and meet industry standards.
The apparatus used in the test includes a vertical flame tester, which consists of a frame holding the specimen vertically, metal plates, and a controlled source of ignition. The specimen must be prepared according to specific dimensions as outlined in the standard. After testing, the fabric is visually inspected for any burn marks or damage.
The results of the test are reported quantitatively by measuring the time it takes for the fabric to ignite and continue burning beyond the point where the flame was applied. The standard also provides criteria for interpreting these measurements in terms of compliance with fire safety regulations.

The CSA D6413 standard is widely recognized for its rigorous testing procedures. It ensures that fabrics meet stringent safety standards, which are crucial in industries where fire hazards can be significant. The ISO standard complements this by providing additional parameters related to flame spread and thermal radiation heat flux.
Industry Applications
- Metalworking
- Automotive interiors
- Petroleum refining
- Aerospace and aviation
The vertical flame resistance test is essential for ensuring that fabrics used in these industries meet the necessary safety criteria. In metalworking, textiles may come into contact with hot surfaces or flames during operations. Automotive interiors require fire-resistant materials to protect passengers from potential hazards. Petroleum refining environments can expose workers to high temperatures and sparks, making flame-resistant fabrics a priority. The aerospace industry demands fabrics that are not only durable but also capable of withstanding extreme conditions without igniting easily.
Use Cases and Application Examples
- Clothing for firefighters
- Upholstery in aircraft seats
- Protective clothing for industrial workers
- Textiles used in home furnishing
| Application | Description |
|---|---|
| Clothing for firefighters | Fabric must resist ignition and continue burning, ensuring the safety of firefighters. |
| Upholstery in aircraft seats | Materials should prevent rapid spread of fire to protect passengers and crew. |
| Protective clothing for industrial workers | Fabric must be flame-resistant to provide protection against accidental ignition. |
| Textiles used in home furnishing | Fabrics should meet fire safety regulations, ensuring that they do not ignite easily or spread flames rapidly. |
