How to inspect a mattress? Mattress inspection methods and key points Inspection, factory inspection, inspection and certification services

A comfortable mattress is crucial for a good night's sleep. Mattresses are available in a variety of materials, including palm, rubber, spring, and latex, each suited to different needs. As an inspector, you need to follow a systematic inspection process when inspecting various mattresses, focusing on common defects and compliance requirements. So, what should a mattress inspection cover? What are some practical inspection methods and key points? This article, combining factory inspection standards with product quality requirements, provides a detailed summary of the complete mattress inspection process and criteria. Save this article for your reference!

1. Product and packaging inspection standards

1. Product inspection points:

• Safety inspection: Ensure that the product has no safety hazards during use and complies with the safety regulations of the destination country.

• Appearance and workmanship inspection: Check for defects such as damage, scratches, and cracks.

• Regulatory compliance inspection: The laws and regulations of the destination country and the customer's technical agreement must be strictly complied with.

• Structural and functional inspection: The product structure, materials, appearance and functions must be consistent with the sample confirmed by the customer.

• Label inspection: All label contents should be printed clearly, with complete information and comply with regulatory requirements.

2. Key points for packaging inspection:

• Packaging strength test: The inner and outer packaging must be strong enough to ensure the integrity of the product during transportation.

• Packaging material conformity: Material type and structure must comply with customer requirements or batch samples.

• Inspection of markings and marks: barcodes, marks and label contents should be accurate.

• Instructions and warnings: All explanatory texts must be printed in the language of the destination country, and the functional description should be consistent with the actual situation.

II. Inspection Plan and Sampling Standards

1. Applicable inspection standards:
   Normal inspection level is usually based on a single sampling plan using internationally accepted sampling standards such as ISO 2859, BS 6001 or ANSI/ASQ Z1.4.

2. Sampling level:
   The number of samples is determined according to the batch size. If the batch is composed of multiple items, the number of samples for each item is determined according to the proportion of their quantity.

3. Acceptable Quality Level (AQL):

• Critical Defects: AQL 0, not allowed.

• Major Defects: AQL is set according to customer requirements and is usually stricter.

• Minor Defects: AQL may be relaxed appropriately, subject to customer agreement.

4. Defect classification principles:

• Serious defects: involving personal safety or violating regulations.

• Major defects: Defects that affect product function, service life or have obvious appearance.

• Minor defects: minor flaws that do not affect the use and sale of the product.

5. Inspection execution conditions:
   Final inspection requires at least 100% of the products to be produced and packaged, with at least 80% packed into outer cartons. If serious defects are found, the entire batch will be rejected, and the customer will decide whether to release the goods.

3. Inspection Process and Classification of Common Defects

During the inspection process, the following items must be inspected item by item and defects must be recorded by category:

1. Packaging inspection:

   • Plastic bags that are oversized and lack a suffocation warning → Serious defect

   • Safety warnings omitted, unclear or incorrectly printed in the destination country's language → Serious defect

   • Origin and importer information missing → Major defect

   • Wrong mark, damaged packaging, damp and mildew, harmful corners, etc. → Determined as serious or major defects based on risk

2. Product self-inspection:

   • Wrong dimensions, unstable structure, material not in accordance with the sample → Major defects

   • Surface stains, slight odor, poor seams, etc. → Minor defects

   • Missing parts, incorrect assembly, malfunction, etc. → Major defects

3. Label and instruction manual inspection:

   • Missing content, description not matching the actual item, not in the target country's language → Major defects

4. Factory Inspection and Systematic Inspection Suggestions

For mattresses, inspectors are advised to integrate factory assessments into their inspection process, including a review of the production environment, quality management system, and raw material control. Based on AQL sampling standards, inspection points can be set up at the end of the production line, during packaging, and in the final inspection area. Key performance tests can be conducted using specialized tools (such as tape measures, hardness testers, and durability testing equipment).

Common defects that need to be focused on include:

• Uneven or collapsed internal filling

• Abnormal spring noise or structural defects

• Fabric is stained, has loose threads, or is discolored

• Environmental protection and safety indicators (such as formaldehyde emission and flame retardancy) do not comply with regulations

By strictly implementing the above inspection process, clearly classifying defects, and continuously tracking factory inspection quality, we can significantly improve the reliability of mattress inspections and customer satisfaction.
