scope of certification

Scope of certification commonly refers to the formally defined boundaries of an organization’s management system certification, such as ISO 9001, AS9100, ISO 13485, or similar standards used in industrial and regulated manufacturing.

What it includes

The scope of certification typically describes:

• Activities and processes covered (for example, design, manufacturing, assembly, inspection, distribution, MRO)
• Products or services covered (for example, precision-machined aerospace components, electronic assemblies, repair and overhaul services)
• Locations or sites included in the certified system
• Applicable standard and possibly industry segment (for example, AS9100 for aerospace production, AS9120 for stockist distributors)

It is usually documented on the certificate issued by a certification body and should match the organization’s actual operations and the implemented management system.

Operational meaning in manufacturing

In industrial and regulated environments, the scope of certification is used to understand which parts of a company’s operations are managed under a given standard. Examples include:

• A plant that is certified to AS9100 for manufacture and assembly of aerospace structures but not for design activities
• A distributor that holds AS9120 certification only for procurement, storage, and distribution of aerospace hardware, not for manufacturing or special processes
• A multi-site organization where only specific facilities are included in the ISO 9001 or AS9100 certificate

Customers, regulators, and internal teams use the scope of certification to determine whether certain products, programs, or processes are covered by the certified management system and to align contractual or regulatory expectations.

What it is not

The scope of certification is not:

• A guarantee of product quality or compliance for all activities of the organization
• A blanket approval for activities, sites, or product lines that are not explicitly included
• The same as an organization’s entire business scope or marketing description

Common confusion

The scope of certification is often confused with:

• Scope of registration: Often used interchangeably, but some bodies use registration to describe listing in their registry. The practical meaning in quality and aerospace contexts is usually the same.
• Scope of accreditation: Refers to what the certification body or test laboratory itself is accredited to do, not what the manufacturer or distributor is certified for.
• Organizational scope: A company may perform activities not included in the certified scope; only the activities named in the scope of certification are under that specific management system certification.

Link to AS9100 / AS9120 context

In aerospace quality management (for example, AS9100 and AS9120), the scope of certification is central when deciding whether a supplier’s certification aligns with customer and regulatory expectations. A distributor with AS9120 certification may or may not satisfy a customer requirement for AS9100, depending on:

• The certified scope (for example, stockist distribution only vs. value-added operations)
• The activities required by the contract (for example, manufacturing vs. purely distributing)
• Regulatory or program-specific requirements that call out a particular standard

Organizations typically review a supplier’s certificate and its scope statement to determine if the certified coverage matches the risk, processes, and controls expected for the supplied products or services.
