The
flame retardancy test includes some of the characteristics related to
whether it is easy to ignite and the ability to maintain combustion. After years of development, the flame resistance test has formed a
variety of standards, as the industry is very focused on the detection
project.
Flame retardant test Purpose:
Through the customer to provide samples of the combustion test, according to the results of the combustion of the corresponding rating, to help customers to product quality control. Flammability rating is one of the most important safety features that are essential for many certifications and are mandatory for many countries.
Flame retardant test is mainly used in plastics, foam, film, textile, paint, rubber, automotive interior parts, electrical and electronic products.
Flame resistance test steps:
Sampling → pretreatment → start adjustment fixture height, flame height, gas flow, etc. → test and record the results → corresponding to the standard level.
The flame retardancy of the material refers to the ability of the material or article to undergo flame burning under specified test conditions. It covers some of the characteristics of whether it is easy to ignite, and the ability to maintain the ability to burn. After years of development, the flame resistance test has formed a variety of standards, as the industry is very focused on the detection project.Different materials have different combustion characteristics, we are based on different materials for testing, in turn, we can also be based on different materials to identify the characteristics of combustion materials.
Depending on the chemical composition of the fiber, the combustion characteristics are also different, so that the major categories of the fiber are roughly distinguished. The combustion characteristics of several common fibers are as follows:1, cotton, linen, sticky fiber, copper ammonia fiber: near the flame: not shrink the melt; contact with the flame: quickly burn; leave the flame: continue to burn; smell: burning paper smell; residue characteristics: a small amount of gray or gray ashes.2, polypropylene fiber: near the flame: melt; contact with the flame: melting, burning; leaving the flame: continue to burn; odor: paraffin flavor; residue characteristics: gray transparent transparent beads.3, spandex fiber: near the flame: melt; contact with the flame: melting, burning; leaving the flame: from the off; odor: special flavor; residue characteristics: white gel.4, polyvinyl chloride fiber: near the flame: melt; contact with the flame: melting, burning, black smoke; leave the flame: self-extinguishing; odor: pungent odor; residue characteristics: dark brown lumps.5, vinylon fiber: near the flame: melt; contact with the flame: melting, burning; leave the flame: continue to burn, black smoke; smell: unique flavor; residue characteristics: irregular coke color hard lumps.6, silk, wool fiber: close to the flame: curly and melt; contact with the flame: curl, melting, burning; leaving the flame: slow burning sometimes self-extinguish; smell: burning hair smell; residue characteristics: loose black particles or coke shape.7, polyester fiber: near the flame: melt; contact with the flame: melting, smoke, slow burning; leave the flame: continue to burn, sometimes self-extinguish; smell: special aromatic sweet; residue characteristics: hard black beads.8, nylon fiber: near the flame: melt; contact with the flame: melting, smoke; leave the flame: from the off; smell: amino flavor; residue characteristics: hard light brown transparent beads.9, acrylic fiber: near the flame: melt; contact with the flame: melting, smoke; leave the flame: continue to burn, black smoke; smell: spicy taste; residue characteristics: black irregular beads, fragile.
