• GET/api/rafs-ddms/relativepermeabilitytests/{record_id}/data endpoint is implemented and available on Swagger
• record_id is the SamplesAnalysis WPC
• User should be able to retrieve bulk data of RelPermeability using new endpoint
• Successful response (200 status code) should retrieve all existing RelPermeability Measurements (bulk data) linked to specified record id (SamplesAnalysis WPC)
• Validation cases should be covered with appropriate status codes
• Response should be returned in interval of 0.1-1 second
