Approved drawing and specification
Drawing, revision, standard and acceptance notes
ROCKVANTA plans industrial parts quality inspection from the approved drawing, project specification and quoted scope. Tell us which dimensions, material results, tests and records matter before the order is released.

Drawing, revision, standard and acceptance notes
Datums, fits, hole patterns and functional dimensions
Grade, hardness and treatment records where required
NDT or product-specific tests where applicable
Reports, identification, packing and third-party timing
Identify the dimensions, material results, process records and release checks required for fit and function before production. ROCKVANTA uses them to prepare the project inspection plan.

State which material documents, heat-treatment records or part-identification links are required for the quoted scope. A certificate is not assumed for every part or order.

Mark the dimensions, datums, fits, hole patterns and mating interfaces that control acceptance. The drawing or inspection plan should distinguish critical points from general reference dimensions.

Define the records, identification and packing checks that must be complete before release. Destination, preservation and third-party timing can change the handover plan.
The part definition decides which inspection methods are useful. Method, location, frequency, acceptance reference and report format remain project-specific.
Critical dimensions and geometric relationships can be checked against the approved drawing or agreed inspection plan. Exact tolerance and sampling requirements must come from the project definition.

Hardness testing can be included where material condition, heat treatment or wear performance needs to be verified. The method, location and record requirement are confirmed for the quoted part.

NDT may be planned for specified material, surface or weld conditions. The method, acceptance reference, inspection stage and report requirement must be agreed before work begins.

Rotation, runout, resistance, sealing or other product-specific checks can be reviewed where applicable to the quoted roller.

Runout, balance or another project-specific check can be reviewed for the quoted pulley. No single test package is assumed for every product.
A useful plan keeps the requirement, inspection stage, record and release decision tied to the same quoted scope.
Confirm the drawing, revision, material, standard, critical interfaces and unresolved points.
Set the applicable checks, acceptance references, inspection stages, records and third-party attendance.
Carry out the agreed in-process or final checks and connect the records to the relevant part or order identification.
Confirm the required inspection status, documents, identification and packing before shipment preparation.

An inspection record is useful only when its purpose and owner are clear. Depending on the quoted scope, the package may include:

For standard products or custom manufacturing orders, third-party inspection can be arranged where required. The buyer may appoint an inspector, nominate an inspection body or ask ROCKVANTA to coordinate with a suitable provider.
Inspection timing, scope and cost must be agreed before the order or shipment. Inspection, reinspection and report fees are buyer-paid.
Certificates and sample test reports are available below, with the holder, scope, dates and document numbers shown for your review.
Mark the critical dimensions and test requirements on your enquiry. We select the relevant instruments and test machines, then agree the acceptance limits and records for the order.

ROCKVANTA owns and operates five specialized manufacturing bases. Our team reviews the part, production, inspection and document requirements, assigns the relevant base and coordinates the applicable hold points.
Inspection equipment, approvals, available capacity and test coverage are confirmed for the specific RFQ.
How We Select a Manufacturing BaseReview the approved requirements.
Assign the relevant manufacturing base.

Confirm release and packing requirements.


A useful inspection enquiry shows what must be checked, when it must be checked and what record is needed. Mark any open point for technical review.
