Critical 1 Spare Parts Definition
What are Critical 1 Spare Parts?
Critical 1 (C1) parts are parts that may fail with no warning, may not show signs of wear, or may cause other parts to fail. They cause a machine failure with no work around. These are the parts that most concern our customers as their failure can stop a production line.
C1 parts are identified by engineering and product support teams during the product development/introduction process.
C1 lists are generated and tracked as part of the development cycle and are made available prior to shipments of production volumes to customers.
As a guideline C1 parts will not be duplicated in RPKs. There may be exceptions that will require cross functional agreement.
What is NOT typically considered a Critical 1 Spare Part:
Consumables or wear parts
High usage spares
Exceptionally robust parts or assemblies
General Hardware (typically)
What is the key difference between Critical 1 and Replacement Parts Kits (RPK)?
Replacement parts kits (RPK) include items customers are expected to need within 6 months of use. Examples of parts in the RPK includes consumables items, wearable parts and predictable failures.
Typical RPK items:
Hardware associated with general maintenance
