Step 1 for Applying NFPA 2112: Which Products Are Suitable for Application

Products covered by NFPA 2112 include various types of flame-resistant clothing items used by industrial workers, such as:

Shirts: Flame-resistant shirts designed to cover the upper body, providing protection for the torso and arms.

Pants: Flame-resistant pants or trousers used to cover the lower body and provide protection for the legs.

Coveralls: Flame-resistant coveralls that offer full-body coverage and protection from flash fire hazards.

Jackets and Outerwear: Flame-resistant jackets or outerwear intended to provide additional protection against flash fire hazards in cold climates or specific working environments.

Bib Overalls and Workwear: Flame-resistant bib-style overalls or workwear that combines the upper body with pants or trousers for specific work tasks or industries.

Lab Coats and Smocks: Fire-resistant lab coats or smocks used in laboratory or industrial settings where flash fire hazards may be present.

Step 2 for Applying NFPA 2112: Sample Preparation

Sample preparation for NFPA 2112 testing includes:

Determining the required number and size of samples based on testing objectives and requirements.

Inspecting sample quality to ensure there are no damages, defects, or other issues.

Pre-treating samples: such as washing, drying, etc.

Preparing testing instruments.

Step 3 for Applying NFPA 2112: Testing the Samples

(1)Vertical Flame Test. Expose the material to a standard flame for 12 seconds, then remove the flame to determine whether it ignites and the length of burn damage.

(2)Thermal Protective Performance (TPP) Test, which evaluates protection against a combination of thermal radiation and convective heat.

(3)Thermal Manikin Test.

(4)Thermal Stability Test.
