QC/T 216 Performance Requirements and Test Method for Carpets Used in Automobiles

The "QC/T 216 Performance Requirements and Test Method for Carpets Used in Automobiles" standard, published among the national standards of the People's Republic of China, describes the definitions, terms, performance requirements, test methods, and inspection rules for carpets used in passenger vehicles. This standard applies to molded carpets for passenger vehicle bodies, i.e., carpet surface materials produced from chemical fiber material by needle punching or spraying, combined with rubber and plastic material as an auxiliary layer through a coating process. It mainly covers felt needle punching carpets, velvet needle punching carpets, striped needle punching carpets, sprayed carpets, and similar types. However, this standard does not apply to floor mats for passenger vehicles.

The QC/T 216 standard applies to molded carpets used in passenger car interiors. These carpets are typically made from chemical fibers produced by needle punching or spraying processes. The carpet serves as the primary floor covering in the vehicle cabin. This standard covers:

• Definitions and terminology related to automotive carpets.
• Performance requirements (e.g., physical characteristics, durability, comfort, and safety aspects).
• Test methods for evaluating these characteristics.
• Inspection procedures (including sampling, evaluation criteria, and quality classification).

This ensures that vehicle carpets meet quality criteria for aspects such as abrasion resistance, compression recovery, dimensional stability, odor emission, flame retardancy (where applicable), and other interior material criteria relating to passenger comfort and longevity.

The latest update to this standard improves requirements, aligns with modern testing protocols, and addresses advances in materials and manufacturing (e.g., improved needle-punched or fringed carpets).

While exact numerical limits vary and full documentation is needed for details, the following are commonly tested features in QC/T 216:

• Wear resistance (e.g., the Taber abrasion test used as a reference in some applications).
• Compressive permanent deformation and elastic recovery (percentage of compression and elasticity after loading).
• Mass, thickness, and loop binding per unit area (for fluffy types).
• Color fastness, pilling resistance, and layer separation resistance.
• Environmental performance (e.g., condensation, odor, harmful substance emissions to meet indoor air quality requirements).
• Flammability (usually referring to relevant standards such as GB 8410 for the combustion behavior of interior materials).

These features ensure the carpet withstands foot traffic, maintains its appearance throughout the vehicle's lifespan, and contributes to a safe, comfortable cabin environment.

The QC/T 216 standard is a recommended industry standard for passenger car floor mats in the Chinese automotive sector. While not mandatory like some GB standards, it plays a very important role in practice.

This standard is considered important for the following reasons:

• Ensuring consistent quality and performance in a high-volume market: China is the world's largest automotive market, with massive passenger car production, both by domestic brands and joint ventures. Floor carpets are high-wearing interior components exposed daily to pedestrian traffic, dirt, moisture, spills, and extreme temperatures. Without standardized performance criteria:
• Carpets can wear out prematurely. Visible damage negatively affects their aesthetic appearance.
• Low elasticity or fiber binding: Fibers can break, creating safety hazards (e.g., loose threads getting caught in shoes).
• Inconsistent suppliers: Quality differences emerge between models or batches.

This standard defines minimum requirements for essential properties (e.g., abrasion resistance with Taber test, compression permanent deformation/recovery, mass per unit area, layer separation strength). This ensures reliable durability throughout the vehicle's service life (typically 10 years / 150.000 km).

• Supporting vehicle homologation and market access: Many Chinese original equipment manufacturers (especially for domestic sales and export) require their suppliers to meet the QC/T 216 standard as part of their internal quality systems or type approval processes. Test results against this standard are often used as crucial evidence for overall vehicle certification or supplier qualification. Poor carpet performance can delay model launches or lead to recalls/field complaints.
• Meeting consumer expectations in terms of comfort, appearance and durability: Modern buyers prioritize a superior cabin feel. Carpets contribute to this:
• Noise reduction (sound absorption).
• Heat insulation.
• Non-slip/dirt-resistant properties.
• Overall perceived quality.

A standardized benchmark helps prevent the use of substandard materials that damage brand reputation and deteriorate rapidly, especially in competitive markets where indoor quality influences purchasing decisions.

• Controlling indoor environmental and health impacts: Carpets can release volatile organic compounds (VOCs), odors, or mist residues that affect indoor air quality. This is a major concern in China due to heavy urban traffic and long commute times. While the GB/T 27630 standard sets broader limits for indoor air quality, the QC/T 216 standard complements this by specifying material and construction requirements that indirectly help control emissions (e.g., better fiber binding reduces dust/particle emissions).

The QC/T 216 standard arose from the fact that, while seemingly simple, floor mats in passenger vehicles are critical to safety, durability, comfort, air quality, and brand image. It provides a clear and unified technical framework that benefits manufacturers, suppliers, regulators, and ultimately consumers in one of the world's most dynamic automotive markets. Without this standard, variability and substandard methods would be more common, leading to higher warranty costs and customer dissatisfaction.

In conclusion, the QC/T 216 standard is part of China’s broader automotive quality system and helps manufacturers (especially domestic and joint venture original equipment manufacturers) ensure consistent quality of interior components. This standard is a key reference for floor mat specifications.
