Once a discrepancy is located, there is no time limit fordetermining the nature or severity of the discrepancy. Viewing angle shall be at 45 and 90 degrees.Visual inspection shall be made by individuals with 20/20 vision, or corrected to 20/20 vision. Except when verifying colors, lighting shall be a minimum of standard overhead florescent factory light ofapproximately 100 foot-candles. See section 6.0 and 7.0 for color matching and gloss inspectionmethods respectively.2.0 Measurable DefectsMeasurable defects on painted surfaces shall not exceed the following limits. A pre-approvedtemplate for measuring area of defects must be used. These defects may include nicks, scratches, contamination, voids, drag marks, inclusions, pinholes, pits, runs, etc. These measurable defectsshall not include adhesion related defects. The defect size criteria described in the following section only covers computer hardware input devices with a viewable top surface area of 36 square inches or smaller.2.1 Class 1 SurfaceA class 1 surface is a primary surface, which may often be viewed by the customer duringnormal use of the product. An example is the top and sides of a product. When necessary fora specific product, more detailed descriptions of the area defining a "class 1" surface shall bedefined via attachment to this document, or by limit samples approved by a Microsoftrepresentative.▪The sum of the length and width of a single painted defect shall not exceed 0.5mm on a class 1 surface.▪The sum of the lengths and widths of multiple measurable painted defects shall not exceed 1.5mm on a class 1 surface.▪Raised surfaces from inclusions or contamination shall also not exceed a height of0.075mm on a class 1 surface.2.2 Class 2 SurfaceA class 2 surface is a secondary surface, which may periodically be viewed by the customer,but is not in direct view during normal use. An example is the bottom of a product. . Whennecessary for a specific product, more detailed descriptions of the area defining a "class 2"surface shall be defined via attachment to this document, or by limit samples approved by aMicrosoft representative.▪The sum of the length and width of a single painted defect shall not exceed 0.7mm on a class 2 surface.▪The sum of the lengths and widths of multiple measurable painted defects shall not exceed 2.5 mm on a class 2 surface.▪Raised surfaces from inclusions or contamination shall also not exceed a height of0.1mm on a class 2 surface.2.3 Class 3 SurfaceA class 3 surface is not visible by customers. An example is the inaccessible inside surfacesof a product. There is no defect size or quantity limitations on class 3 surfaces provided thatfit and function requirements are not impacted.3.0 Visible Adhesion DefectsPainted surfaces shall not exhibit any visible adhesion related defects including blistering, peeling, or bubbles on any surface. When conducting "Drop Tests" associated with either Design VerificationTests (DVT), or Ongoing Reliability Tests (ORT), the paint shall exhibit no visible cracking ordelaminating due the drop.4.0 Visible Surface IrregularitiesAny blemish visible per the above mentioned viewing criteria, which is under the paint finish, such as grinding marks, and tooling marks shall be rejected on class 1 and 2 surfaces, unless they complywith Microsoft approved limit samples. For allowable defects, also refer to “900-300-076 Plastic Parts Workmanship Standards.”5.0 Paint Over-sprayPaint over-spray is not allowed onto surfaces defined as paint free per engineering drawings.Judgments made on overspray, other than those clearly defined by engineering drawings, shall bedetermined using pre-approved limit samples.6.0 Correctness of ColorConfirmation of correct color is to be completed prior to the start of production and monitored during production. During production color is to be confirmed during each shift on 2 parts. Reference MSspecification “Color Correctness Evaluation” (900-300-079). Initial color matching for qualification of new paints shall include approval by a Microsoft Hardware Industrial Design representative, andutilize spectrophotometer to quantify nominal color specification values.7.0 Correctness of GlossThis test shall be conducted during the routine testing for color correctness, above, as well as during the paint selection and Design Verification Testing (DVT) Process. Gloss shall be measured using a60 degree gloss meter. Actual gloss will be specified on engineering drawings.8.0 Paint ThicknessBoth maximum and minimum painted coating thickness shall be specified on engineering designdrawings, as these may vary according to paint type selected. Thickness shall be sampled andmeasured during production at the painting facility. The thickness measurement method is to be pre-approved by Microsoft. The sampling frequency and quantity shall be 2 pieces at production startup during each shift. Parts are to be taken from opposite ends of paint fixtures, where practical to do so.9.0 Paint HardnessPainted coating "pencil" hardness shall be routinely sampled and measured during production at the painting facility, to confirm compliance to engineering design drawings. During production, hardnessis to be confirmed monthly on 3 parts. A minimum hardness of 2H is required when not otherwisespecified by design drawings. Reference ASTM 3363-92 for methodology. Component paintingfactories shall also require a certificate of compliance from paint suppliers.10.0 Human Use Qualification TestThe following Qualification Test is to be performed by Microsoft. After successful results with all of the above criteria, the following test is to be performed on paints, which are desired for use in production.The paint formulation, thickness, and application method shall replicate that to be used in production.Thirty people are to be selected to represent the customer use population and environment. Selectequal numbers of males and females. Each individual is to use their Microsoft hardware product forthe average maximum amount of time per day expected during customer use. Assume the maximum average usage rate of 6 hours/day for a mouse or keyboard. Assume a maximum average usage rate of 2 hours per day for a gaming product. Each person shall as part of the test, liberally apply anybrand hand lotion of their personal choice, at least twice during the day. These individuals shall not be advised on selection of lotion brand, in order to better represent the real customer population. Users will be encouraged to eat and drink the food and beverage of their choice while using the device.Visual inspection for paint deterioration will occur every 30 days. This Qualification test duration willlast at least 90 days prior to start of production with the selected paint. However, the tests willcontinue after Qualification for up to one year, or until the paint specimens begin to fail. An acceptable paint will exhibit no apparent visible deterioration.Cleaning During Testing: Only the following methods of cleaning are allowed during the Usertesting:▪Wiping with a clean, dry cloth.▪Blowing with pressurized air.▪Washing with a cloth moistened with mild dish washing soap andwater.11.0 Reliability Requirements11.1.1 Visual TestNo visible adhesion related defects including blistering, peeling, or bubbles areallowed on any surface.
