Inspection and verification of candles and candle holders, factory inspection and certification services

October 17, 2025

As an important category of daily decorations and festival items, the quality and safety of candles and candle holders directly affect the usage experience and the rights and interests of consumers. To ensure continuous compliance with market entry standards, a professional inspection process and quality certification system are of vital importance. This article will systematically introduce the product definitions, classification standards, and inspection key points of candles and candle holders, providing a complete inspection and certification guide for inspectors.
I. Product Definition and Certification Scope
1. Definition of Candle Products
A candle is a lighting product made of solid hydrocarbons such as paraffin wax, vegetable wax, or animal fat. It has a wick at the center and provides lighting or decorative functions when lit. In the inspection and certification process, the material composition and safety attributes of the product must be clearly defined.
2. Definition of Candle Holders
A candle holder is a base device specifically designed to hold cone-shaped, column-shaped, and tea light type candles. It can be classified by material into categories such as glass, ceramic, metal, and wood, and by structure into types such as single supports and smooth bases. During the factory inspection process, the structural stability and material safety of the candle holders must be confirmed.
II. Professional Terminology Explanation (Inspection Certification Standards)
To ensure the professionalism and consistency of the inspection process, the following key terms need to be understood:
Paraffin: A waxy, white/colourless solid mixture of hydrocarbons, requiring material safety certification.
Wick core: A fiber guiding system made through weaving or winding techniques, which affects the combustion performance.
Candle wax: A type of wax used for candles that are placed in dedicated containers. Such containers must undergo heat resistance testing.
Wax pool: The area where molten wax liquid is formed during the combustion process. Its size must comply with safety standards.
Candle flickering fire: A dangerous phenomenon where steam ignites the entire oil pool. This must be eliminated during the inspection process.
Second-degree combustion: An unstable combustion state that is not self-sustained by the wick core, and is a serious quality defect.
Flow wax: An unexpected overflow of molten wax liquid, indicating a design flaw in the product structure.
End of service life: The self-extinguishing performance at the time of design life expiration is crucial for safety during use.
Tea light: A type of safe candle placed in a metal, glass or plastic container
III. Product Classification and Inspection Standards
A. Classification by Processing Method for Certification
Wax stick type: Conical and cylindrical candles formed by mechanical pressing
Wax-infused products: Candles that are poured into containers such as clay jars or glassware.
B. Classification by Appearance Characteristics
Special visual effect products such as snowflake wax, jelly wax, and layered wax
C. Classification and Certification According to Specifications
Tea light wax, stick wax, pressed column wax, offering wax, floating wax
D. Special Certification for Craft Candles
Craft candles are innovative products that achieve functions such as colored flames and fragrance release through special formulations. During the inspection process, the following aspects should be given particular attention:
Color Flame Candles: Safety Verification of the Metal Ion Coloring Mechanism
Crystal Jelly Candle: Dual verification of transparent texture and burning performance
Scented candles: Environmental and health certifications for fragrance additives
Music Candle: Safety Isolation Verification of Electronic Components and Combustion System
IV. Key Inspection Items at the Site
1. Material Safety Certification
The wax-based material complies with environmental protection and health standards.
The wick's oil-conducting performance is stable and reliable.
The additives such as pigments and flavors have passed the safety tests.
2. Structural Integrity Inspection
The candle body has no manufacturing defects such as cracks, bubbles, or impurities.
The wick is centered and firmly fixed.
The container candle is sealed tightly and there is no risk of leakage.
3. Combustion Performance Test
The combustion process was stable, with no popping or wax splattering.
The height of the flame complies with safety standards.
The burning duration reaches the nominal value.
Self-extinguishing performance is reliable (if applicable)
4. Candelabra Safety Certification
Sturdy structure, meets load-bearing test standards
The material's heat resistance meets the requirements.
The surface is smooth without any burrs.
V. Inspection Process and Certification Standards
1. Sampling Inspection Plan
Random sampling is conducted in accordance with the AQL standard.
Increase the sampling rate for key safety projects
Establish a batch tracking management system
2. Defect Level Determination
Serious Defect: Zero tolerance for any items related to combustion safety
Main defect: Strict control over items that affect the functionality of the product.
Minor defect: The appearance flaws are within the acceptable range.
3. Certification Document Requirements
Material Safety Inspection Report
Test Record of Combustion Performance
Production process flow document
Conformity Declaration
VI. Key Points for Factory Audit
To ensure that the candle and candle holder products consistently meet the quality certification requirements, during the factory audit, special attention should be paid to the following:
Raw material control: Establishing inspection standards for wax, additives, and wick for incoming materials
Production process control: Develop operation standards for key procedures such as melting, pouring, and molding.
Combustion testing chamber: Equipped with standardized facilities for combustion performance testing
Environmental management: Ensure the control of temperature and humidity in the production area and maintain fire safety.
Personnel training: Enhance the professional skills of quality inspection personnel and unify the inspection perspective.
Inspection and Certification Summary
The inspection and factory verification of candle and candle holder products is a highly specialized systematic project that requires comprehensive testing from material safety, structural design to combustion performance. Enterprises should establish a complete quality management system and strictly control each production process to ensure that the products pass relevant safety certifications.
