The processing methods of leather goods and handbags are mainly manual, and the methods of quality inspection are mostly manual operations. Based on nearly 23 years of production experience, the company has summarized a set of freshly baked luggage inspection standards and methods, which can be referenced by various leather manufacturers. At the same time, you are welcome to discuss corrections.

1. Sampling test standards.

A method of sampling inspection for leather goods and handbags. The plan is as follows:

1. ANSI/ASQ Z1.4-2008 statistical sampling procedure is a commonly used appearance quality inspection procedure.

ANSI/ASQ Z1.4-2008 is the most widely accepted sampling method, which has the advantage of clearly defining the sampling samples of the designated inspection goods and the maximum allowable number of defective samples among the sampling samples. Unless required by the customer, this inspection method is followed in the inspection of leather goods and handbags.

Among the bags and handbags produced by Guangzhou leather goods manufacturer Guangzhou Bagu Wenpi Leather Co., Ltd., the most commonly used sampling plans are: the initial and mid-term inspections use a single sampling plan LEVEL I, and the final inspection once a sampling plan LEVEL II. Personnel, or customers, or professional institutions.


The defects of leather goods and handbags are classified as: serious defects, major defects, and minor defects. The definitions are as follows:

Severe defect: refers to a situation in which leather goods, bags, handbags may cause personal injury or insecurity during use, or the defect violates relevant mandatory laws and regulations.

Main defect: This defect may cause the inspection result to fail. Genuine leather goods, handbags and luggage products generally do not have serious defects, but the main defects are often found in some factories.

Minor defect: This defect will not reduce the usability of leather goods and bags, but it is still a workmanship defect that exceeds the defined quality standards. Because ANSI/ASQ Z1.4-2008 is based on random sampling, a small number of defects can be considered acceptable. As leather goods, handbags and bags are handmade products, there are a few minor defects acceptable.

AQL must also be considered when using the identified defects. Acceptable quality limit AQL represents the worst process average quality level that can be allowed when a continuous series of batches is submitted for acceptance sampling. The acceptable quality level is the largest percentage of defects, which is used as an average method to measure quality in the sampling inspection of leather goods and handbags. Different defects can be designed according to their different AQL.
