Conformity Classification

Quality Hub GINEZ uses a three-level conformity classification system to evaluate product quality based on multiple parameters: sólidos (solids), pH, and appearance.

​
Classification Levels

​
Conforme (Conforming)

Definition: Product meets all applicable quality standards. Status: 'conforme' Characteristics:
  • All measured parameters are within specification limits
  • Product can be released for distribution
  • No corrective action required
Example: 
{
  phStatus: 'conforme',
  solidsStatus: 'conforme',
  appearanceStatus: 'conforme',
  overallStatus: 'conforme',
  isConform: true,
  failedParams: []
}

​
Semi-Conforme (Semi-Conforming)

Definition: Product falls in tolerance zones but outside strict specifications. Status: 'semi-conforme' Characteristics:
  • Measurements are between red and yellow control chart limits
  • Within 5% tolerance of specification limits
  • Requires evaluation before release
  • May require process adjustment
Semi-Conforme products are within tolerance but indicate the process is drifting toward non-conformity. Monitor these closely.
Example: 
{
  phStatus: 'conforme',
  solidsStatus: 'semi-conforme',
  appearanceStatus: 'conforme',
  overallStatus: 'semi-conforme',
  isConform: false,
  failedParams: ['solidos']
}

​
No Conforme (Non-Conforming)

Definition: Product fails to meet quality standards. Status: 'no-conforme' Characteristics:
  • One or more parameters outside tolerance limits
  • Cannot be released without corrective action
  • Requires NCR (Non-Conformity Report) documentation
  • May require rework, reprocessing, or disposal
Example: 
{
  phStatus: 'no-conforme',
  solidsStatus: 'conforme',
  appearanceStatus: 'no-conforme',
  overallStatus: 'no-conforme',
  isConform: false,
  failedParams: ['ph', 'apariencia']
}

​
Not Applicable (NA)

Status: 'na' Definition: Parameter not required for the product type.
Many products don’t require all parameters. For example, aromatizantes (air fresheners) don’t require sólidos or pH measurements.

​
Parameter Evaluation

​
Sólidos (Solids Content)

Method: Three-level control chart classification 
let solidsStatus: ConformityLevel = 'na'
if (avgSolids !== null && stdSolids && 
    stdSolids.min !== undefined && stdSolids.max !== undefined) {
  const specMin = stdSolids.min
  const specMax = stdSolids.max
  const warnMin = specMin * 0.95
  const warnMax = specMax * 1.05

  if (avgSolids >= specMin && avgSolids <= specMax) {
    solidsStatus = 'conforme'
  } else if ((avgSolids >= warnMin && avgSolids < specMin) || 
             (avgSolids > specMax && avgSolids <= warnMax)) {
    solidsStatus = 'semi-conforme'
    failedParams.push('solidos')
  } else {
    solidsStatus = 'no-conforme'
    failedParams.push('solidos')
  }
}
Location: lib/analysis-utils.ts:54-73

​
pH (Acidity/Alkalinity)

Method: Simple pass/fail evaluation 
let phStatus: ConformityLevel = 'na'
if (record.ph !== null && stdPH) {
  if (record.ph >= stdPH.min && record.ph <= stdPH.max) {
    phStatus = 'conforme'
  } else {
    phStatus = 'no-conforme'
    failedParams.push('ph')
  }
}
Location: lib/analysis-utils.ts:76-84
pH currently uses binary pass/fail logic. There is no Semi-Conforme classification for pH.

​
Apariencia (Appearance)

Method: String matching against standard appearance values 
let appearanceStatus: ConformityLevel = 'na'
if (record.apariencia && stdApp) {
  if (record.apariencia.toLowerCase().includes(stdApp.toLowerCase()) || 
      stdApp.toLowerCase().includes(record.apariencia.toLowerCase())) {
    appearanceStatus = 'conforme'
  } else {
    if (record.apariencia.toUpperCase() === stdApp.toUpperCase()) {
      appearanceStatus = 'conforme'
    } else {
      appearanceStatus = 'no-conforme'
      failedParams.push('apariencia')
    }
  }
}
Location: lib/analysis-utils.ts:87-101 Standard Values:
  • CRISTALINO - Clear/transparent
  • OPACO - Opaque
  • APERLADO - Pearlescent

​
Overall Conformity Logic

Currently, overall status is determined only by sólidos status as specified by user requirements. pH and appearance are evaluated but don’t affect overall conformity.
const overallStatus = solidsStatus
const isConform = overallStatus === 'conforme'
Location: lib/analysis-utils.ts:114-118

​
Future Enhancement: Worst Status Algorithm

The code includes a getWorstStatus function for comprehensive evaluation: 
const getWorstStatus = (statuses: ConformityLevel[]): ConformityLevel => {
  const activeStatuses = statuses.filter(s => s !== 'na')
  if (activeStatuses.length === 0) return 'na'
  if (activeStatuses.includes('no-conforme')) return 'no-conforme'
  if (activeStatuses.includes('semi-conforme')) return 'semi-conforme'
  return 'conforme'
}
Logic:
  1. Filter out ‘na’ statuses
  2. If any parameter is ‘no-conforme’, overall is ‘no-conforme’
  3. If any parameter is ‘semi-conforme’, overall is ‘semi-conforme’
  4. If all parameters are ‘conforme’, overall is ‘conforme’

Data Structure

​
ConformityLevel Type

export type ConformityLevel = 'conforme' | 'semi-conforme' | 'no-conforme' | 'na'

​
AnalysisResult Type

export type AnalysisResult = {

  failedParams: string[] // 'ph', 'solidos', 'apariencia', 'color', 'aroma'
  phStatus: ConformityLevel
  solidsStatus: ConformityLevel
  appearanceStatus: ConformityLevel
