Technical Specification — definition
Structured document describing the functional, performance, materials, and interface requirements an item of equipment or system must meet.
Technical specifications translate operational and process requirements into measurable criteria such as capacity, tolerances, materials of construction, utilities consumption and control interfaces. They form the reference basis against which supplier proposals and delivered equipment are evaluated.
Why it matters to industrial buyers
A precise specification reduces the likelihood of receiving non-comparable quotes and limits disputes over whether delivered equipment meets requirements.
Key reference points
Common contents
Typically includes capacity, materials, utilities, control philosophy, applicable standards and acceptance criteria.
Level of detail
Specifications for special-purpose machinery are commonly more detailed than for standard catalogue equipment.
Commonly confused with
Scope of supply
A technical specification defines what the equipment must do; scope of supply defines what is included, excluded and whose responsibility each element is.
How it is used in practice
A technical specification for a filling machine states output rate, container formats, changeover time and hygienic design standards.
Frequently asked questions
Who typically prepares a technical specification?
It is commonly prepared by the buyer's engineering team, an independent consultant, or jointly with a shortlisted supplier.
How detailed should a technical specification be for an RFQ?
It should be detailed enough that independent suppliers would interpret the scope consistently and quote comparable prices.
