ACCEPTANCE INSPECTION SPECIFICATIONS OF PLASTIC MOLDED PARTS

This standard provides the acceptance inspection standard of plastic molded parts for PC which Fujitsudevelops and designs, and procures from domestic and overseas manufacturers according to purchasespecifications. The purpose is to ensure the quality efficiently and properly.

This standard can apply correspondingly to plastic parts (manufactured by machining) of whichappearance quality is required.

This standard applies to the acceptance inspection of plastic molded parts for PC which Fujitsu developsand designs, and procures from domestic and overseas manufacturers according to the purchasespecifications. However, when the special specification is specified in the individual specification(including limit sample) or the drawing, it has priority.

This standard conforms to Fujitsu standard BAFV070/004 “ACCEPTANCE INSPECTIONSPECIFICATIONS OF PLASTIC MOLDED PARTS”, and there is no difference on the contents andcriteria between the two.

Zone ExampleUse / Function

Inspection items, methods of judgment and criteria of judgment are divided into A, B, BZ, and Caccording to product’s uses and functions as below. A, B, BZ, and C should be applied tocompletely assembled products (as they are located), not each parts. Figure-1 shows examples ofdivisions of exterior appearance. When there is no indication in the drawing, it is necessary toadjust and specify divisions at the phase of the estimate.

BZ（Quasi-Effective

Surface)

It means the surface (front face) or the part of a surface that there aresignificant requests for the design of the product.- It means the area where users can see while operating PC normally.

A（Effective Surface)

Except for the effective surface (A) and B, it means the surface or thepart of a surface that has a little impact on product’s appearancequality, typically the back part of a product.It means the part that users can hardly see when PC is installednormally.

Operating portionon the surface ofKeyboardUpper face and sideface of PC

C（Non-Effective

Surface)

It means the surface or the part of a surface other than those above.

- It means the area that there is no request for the design of theproduct, and the product’s appearance quality is not injured.

Except for the effective surface (A), it means the surface (upper / sideface) or the part of a surface that has an impact on product’s- Also, it includes the surface or the part of a surface that users cansee when opening covers while using PC.

- Inspection Condition of Appearance QualityFor the purpose of judgment of appearance quality, the condition is as follows.

(2)Direction of Light source: Vertical direction to an inspection target.700 to 1500 Lux.

Visual inspection:

The eyesight should be 1.2 or more on both eyes (glasses and contact lenses areacceptable).

5 Eyesight

InspectionMethod

Defects which are found out should be judged according to the criteria ofjudgment. Defects should be judged by “easy to notice”. The size of a defectshall be according to “Dirt Comparison Chart”. When there are doubts on theinspection result, the judgment of the quality should be decided by people of in-house related sections.

3Visual

Inspection AngleIt should be looked at an inspection target between angles of 45 degrees and -45degrees from horizon.

It should be inspected at the distance of 30cm from an inspection target.4InspectionDistance

It should be measured on the surface of an inspection target. (Without regard toreflection)
