45 Degree Flammability Tester | ASTM D1230
The 45-Degree Flammability Tester is designed to evaluate the flame propagation characteristics of textile materials when exposed to a controlled ignition source at a 45° angle. It is widely used in the apparel, home textile, toy fabric, and furniture industries to measure burn time and classify the flammability level of fabrics.
The instrument uses a stainless-steel test chamber with an observation window, enabling clear visual monitoring during testing. A precision burner, adjustable ignition time, and automatic timing system ensure accurate and repeatable results. The tester provides reliable data to help manufacturers identify fire-risk materials and meet mandatory safety requirements for global markets.
Applications
The instrument is used across multiple industries where textile flammability is a critical safety factor. Typical applications include:
Clothing & Apparel Testing
Used to assess fabrics for everyday clothing, workwear, school uniforms, and accessories. Manufacturers rely on this test to ensure their materials do not exhibit rapid flame spread, reducing potential hazards to end users.
Home Textiles & Interior Furnishings
Evaluates curtains, upholstery, mattress fabrics, bedding, and other domestic textiles. It helps designers and quality teams select fabrics that comply with fire-safety requirements for homes, offices, hotels, and public buildings.
Toy Fabrics & Children’s Products
Testing of plush toys, stuffed animals, play tents, and textile components used in children’s items. Ensures products meet safety regulations and prevent accidental ignition risks.
Soft Furniture & Decorative Materials
Determines the burning behavior of fabrics used in sofas, cushions, seat covers, and decorative panels. Supports compliance with regional fire codes and improves product safety.
Material Development & Quality Control
Provides critical data during R&D for flame-retardant fabrics, coatings, and chemical treatments. In production environments, the tester verifies batch consistency and ensures each lot meets required flammability performance.

FAQ
1. What does the 45-degree flammability test measure?
It measures how quickly a textile burns when exposed to a small flame at a 45° incline. The resulting burn time is used to classify the fabric’s flammability level.
2. Why is this test important for manufacturers?
It identifies materials that burn too rapidly and may pose fire hazards. Many markets require flammability classification before products can be sold, especially clothing and home textiles.
3. What types of fabrics can be tested?
Most woven, knitted, and nonwoven fabrics, including apparel textiles, upholstery materials, toy fabrics, and decorative fabrics.
4. Does the tester meet mandatory regulatory standards?
Yes, it fully complies with ASTM D1230, CFR 16 Part 1610, CAL TB 117, NFPA 702, and GB/T 14644, ensuring global market acceptance.
5. Can the ignition time be adjusted for different standards?
Yes. The system allows presetting 1s, 5s, or 20s ignition times, suitable for multiple test protocols.
