Different Types of Tests Perform to Ensure Candle Safety

Safety tests for candles help candle makers reduce risks like household fires, burn injuries, property damage, and adverse effects from toxic coating materials or soot. It will certify that candles meet regulatory standards across the globe. Safety standards compliance provides consumers with confidence that a manufacturer’s products are safe to use in their homes. A reputable candle lab offers performance tests such as burn time, burning behavior, stability, soot/smoke, temperatures, flame heights, wick behavior, and safety of additional ingredients.

Testing Materials

Experts analyze and test lead and heavy metal content in dyes, surface coatings, lacquers, embedded materials, candle wax, and wick to prevent harm to human health and the environment. Also, material and performance tests are carried out on candle holders, containers, and lanterns to confirm their stability and safety in product design.

Evaluating Labels

Candle products need to be labeled or packaged with caution statements, product use information, and safety guidelines to prevent possible dangers and misuse. A customized analysis can be done of proper wording, illustrations, and placement to create packaging texts that consumers can easily understand.

Evaluating Toxicity

Expert candle testers can assist in toxicology evaluations of candle products to make sure the substances used in the making of candles like additives, colorants, and additives are safe. Also, this ensures the products comply with legislation.

Testing for Soot

Soot is a product when the wax of the candle presents incomplete combustion. Soot is composed of microscopic, solid particles released into the atmosphere as the candle burns. Candle makers have to choose the correct combination of wax types, candle shapes and sizes, as well as wick sizes to produce the best possible burning performance. Candles that show a high degree of sooting have a poor quality component. For instance, a wick that has poor posture may lead to a higher level of sooting occurring during burning. Most candle wicks are made with a slight curvature to ensure its gradual incineration. If incineration doesn’t happen and the wick becomes elongated, the wax may be showing incomplete combustion, leading to the candle burning with a more sooty flame.

To determine the amount of soot a candle produces, the product to be tested is placed inside a soot machine. The tester will list the candle and let it burn for five minutes before placing a clear piece of heat-resistant glass above the candle’s base. Any residual sot released during the burn process is captured by the glass. Then, the tester will compare the amount of soot captured against a clear piece of glass.
