Peony&Buyoh-Procedures and Guidelines for Auditing by ourselves

 

--------程序Procedure:

 

*选择需要抽检订单的数量 

*Select the specified lot or the lot being audited. The lot size is the total units in the specification

 

**根据AQL2.5的抽检要求,确定需要抽检的数量以及能够接收的疵点数量;例如订单数量是2500件,需要抽检的数量是50件,而能接收的疵点数量为3个。 

**According to the sampling plan under the 2.5 AQL, determine the number of units to inspect. These units will be your

 

sample size. Example: if your lot size is 2500; then your sample size would be 50 units accepting 3 defects.

 

***抽检的成衣品质包括 包装,商标,尺寸,颜色,做工等等。

*** The sample size will be thoroughly inspected for: packaging, labeling, size, color and workmanship.

 

-------确认抽检是否通过Pass / Fail Guidelines:

 

*判断抽检是否合格,对照AQL2.5中的标准,比如订单数量是2500件,需要抽检的数量是50件,只要疵点数量少于等于3个,即为通过。 

*An audit is considered passing if the sample size meets or is lower than the 2.5 AQL chart for a specified lot size.

 

** 如果第一次抽检结果没有达到AQL2.5的标准,需要重新按照第一次的的抽检方法重新检验,如果第二次抽检结果通过,此货物抽检结果视为通过。

** If the initial sample size exceeds the 2.5 AQL chart for a specified lot; an additional sample size must be pulled from that

 

same lot. If the second sample size meets or is lower than the 2.5 AQL chart, the audit results in a pass.

 

*** 如果2次抽检都没有达标的话,必须执行100%抽检,直到确认货物没有问题才能允许出货。

***If the first and second sample size exceed the 2.5 AQL chart for a specified lot; the audit results in a fail and must

 

go through a 100% re-inspection for that specified lot. Products that fail cannot be shipped until it receives a passing status .

Quality control is practiced right from the initial stage of sourcing raw materials to the stage of final finished garment. For apparel quality is calculated in terms of quality and standard of fibers, yarns, fabric construction, color fastness, surface designs and the final finished garment products. However quality expectations for export are related to the type of customer segments and the retail outlets.

 

How to make sure the good quality of our products, Let’s do below jobs:

  1. Understanding the customers' quality requirements.
  2. Organizing & training quality control department.
  3. Ensuring proper flow of quality requirements to the QC department.
  4. Ensuring proper flow of quality requirements to the Production Department.
  5. Establishing quality plans, parameters, inspection systems, frequency, sampling techniques, etc.
  6. Inspection, testing, measurements as per plan.
  7. Record deviations
  8. Feedback to Production Department.
  9. Plan for further improvement.

 

Establishing the Quality Requirements:

The first step for quality control is to understand, establish & accept the customers' quality requirements. This involves the following steps.

  1. Getting customers specifications regarding the quality
  2. Referring our past performance
  3. Discussing with the Quality Control Department
  4. Discussing with the Production Department
  5. Giving the Feed Back to the customers
  6. Receiving the revised quality requirements from the customers
  7. Accepting the quality parameters

 

Various Steps of Inspection & Quality Control:

The following levels are discussed at the Garment Making Department assuming that this department is receiving the ready to cut dyed & finished fabrics from the Dyeing & Finishing Department.

 

 

 

Pre-production Inspection

The following parameters & defects are checked prior to cutting.

  1. Shade Matching
  2. Fabric Construction
  3. GSM (grams per square meter)
  4. Whales & courses if required)
  5. Diameter
  6. Dyeing Levelness
  7. Ecological parameters if required
  8. Softness
  9. Shrinkage
  10. Matching of Rib, Collars & Cuffs
  11. Fabric Holes
  12. Vertical & Horizontal Stripes
  13. Knitting defects such as missing loops, sinker lines, etc.
  14. Bowing
  15. Skewing
  16. Yarn defects such as thick & thin places
  17. Dirt & Stains
  18. All accessories, we have to check if the quality of all accessories meet buyer’s requests.

 

During Production Inspection

  1. Verify cutting patterns
  2. Cut components measurements
  3. Cutting shapes
  4. Fabric defects
  5. Other specific parameters as required by the customers Rib, Collars & Cuffs matching
  6. Stitching defects
  7. Sewing threads matching
  8. Dirt & Stains
  9. Measurements
  10. Labels
  11. Trims & Accessories

  2. Body width
  3. Shoulder length
  4. Arm hole
  5. Arm Opening
  6. Sleeve length

  18. Inseam
  19. Leg opening

 

Many of the important parameters of Pre-productions, During productions & Final inspection parameters. This is to ensure that wrong or major defective garments are not packed.

 

 

AQL ( Acceptable Quality Level )

A certain proportion of defective will always occur in any manufacturing process. If the percentage does not exceed a certain limit, it will be economical to allow the defective to go through instead of screening the entire lot. This limit is called the "Acceptable Quality Level" ( AQL )

 

Considering the practical & economic aspects, Sampling Techniques are adopted to Accept or Reject a Lot on the basis of the Samples drawn at Random from the lot. It has been found and accepted that a scientifically designed sampling & inspection plan protects a Manufacturer as well as the Buyer economically.
