      1. Mount the Sample
      - Place the fabric vertically in the frame inside the test chamber. - Ensure it's held securely with no folds or slack.  
      1. Set Up the Burner Position the burner at the required angle (usually 90° for vertical tests).
      - Adjust flame size according to the standard (about 38 mm for ASTM D6413).
      1. Ignite the Flame - Apply the flame to the bottom edge of the fabric for 12 seconds.
       
      1. Observe and Measure - Start timing when flame is applied.
      - Measure: - After-flame time (how long it burns after flame removal) - After-glow time (how long it glows after burning stops) - Char length (distance burned vertically)  
      1. Record the Results
      - Repeat the test on multiple samples (usually 5) and calculate averages.  
      1. Compare with Standards
      - Evaluate whether the results meet the required flame resistance limits.     fabric flame retardant tester IV type (small 450 method) Scope of application It is used for testing the intensity and speed of burning of flammable textile materials after ignition.

      Fastness Rotary Friction Tester

        A Fastness Rotary Friction Tester, also known as a Rotary Crock meter, is a specialized instrument used to evaluate the color fastness of textiles and materials when subjected to rotational rubbing. This test simulates the wear and friction that fabrics experience during use, helping manufacturers assess the durability of dyes and finishes. Purpose of Fastness Rotary Friction Tester The primary function of the Fastness Rotary Friction Tester is to determine how well a fabric's color withstands rubbing, both in dry and wet conditions. This is crucial for ensuring the longevity and appearance of textiles in real-world applications, such as clothing, upholstery, and footwear.   Working Principle of Fastness Rotary Friction Tester The tester operates by applying a specified pressure to a fabric sample using a standardized rubbing finger covered with a test cloth. The rubbing finger performs a set number of rotational movements (typically 1.125 turns clockwise followed by 1.125 turns counterclockwise) over the fabric surface. After the test, the degree of color transfer to the test cloth and any changes in the fabric's appearance are evaluated against standardized gray scales.   Common Testing Standards - AATCC 116: Colorfastness to Crocking: Rotary Vertical Crock meter Method. ISO 105 X16: Textiles—Tests for color fastness—Part X16: Color fastness to rubbing—small areas. - SATRA TM8: Color fastness to rubbing.   Key Specifications of Fastness Rotary Friction Tester - Rubbing Head Diameter: Typically 16 mm. - Applied Pressure: Approximately 1134 grams (11.1 N). - Rotation: 1.125 turns clockwise followed by 1.125 turns counterclockwise. - Sample Size: Commonly 60 mm × 60 mm. - Test Cloth: Standardized white cotton cloth, either dry or wetted depending on the test condition.   Benefits of Fastness Rotary Friction Tester - Realistic Simulation: Mimics the actual wear and friction fabrics undergo during use. - Versatility: Applicable to a wide range of materials, including textiles, leather, and printed fabrics. - Quality Assurance: Ensures products meet industry standards for color durability. - Standard Compliance: Aligns with international testing standards, facilitating global trade and quality benchmarks.   Applications Fastness Rotary Friction Tester - Textile Industry: Assessing the color durability of garments, upholstery, and other fabric products. - Footwear Manufacturing: Testing the colorfastness of shoe uppers and linings. - Automotive Interiors: Evaluating the wear resistance of seat covers and other interior fabrics.
