Bond Tester Buying Guide: Modes, Probes and Application Evidence
A bond tester can offer several inspection modes, but the useful purchase is a supported combination of instrument, probe, cable and application evidence. Start with the construction and required examination, then confirm the delivered configuration.
For: U.S. NDT equipment coordinators, quality staff and inspection business owners
Describe the bonded construction and required question
Ask the technical owner to identify the construction being examined and the relevant inspection question. Honeycomb sandwich, laminate composite and metal-to-metal bonding are not interchangeable application descriptions. Record the available information about the part and the approved method without asking purchasing to infer suitability from the general term composite. The equipment should serve a defined examination requirement.
Include the required record and interpretation responsibility in the application brief. This guide supports procurement and evidence management. It does not select frequencies, probe pressure, scan paths, coupling practice, response thresholds or acceptance limits. Those decisions belong to the applicable procedure, manufacturer instructions and qualified personnel. A supplier demonstration should provide evidence for that process, with the actual construction and configuration identified rather than a broad promise to detect every bond condition.
Distinguish the available bond-testing methods
Evident's probe overview separates pitch-catch, mechanical impedance analysis and resonance probe families and describes different application roles. The distinction matters when writing a request for quotation. A probe appropriate to one approved bond-testing method should not be treated as a universal sensor for every construction or required result.
Ask the supplier to map the proposed method and probe to the intended task, then have the technical owner review that mapping. Preserve the supporting documentation and any application-specific evidence. Do not choose the mode merely because it produces the most visually dramatic display during a demonstration. The procurement decision should explain which method the organization intends to use, which configuration supports it and what limitations remain for other constructions or questions outside that scope.
Confirm the installed instrument variant
The September 2022 BondMaster manual distinguishes the B600 pitch-catch configuration from the B600M configuration that also includes MIA and resonance. This is a documented model example, not a claim that every product-family listing automatically includes every mode. Ask the supplier to identify the exact current offered model and installed capabilities.
Compare the instrument used in the trial with the quotation. If the demonstration uses a multimode unit and the offer describes a basic unit, resolve the difference before acceptance. Record upgrade possibilities separately from delivered capability and obtain current written confirmation of availability. An upgrade described in a historical manual is useful background, but it should not be counted as purchased functionality unless the actual offer includes the required option and supporting items.
Specify the probe and cable as application items
Request the exact probe model, compatible cable and any required supporting accessories for each intended method. A probe kit may contain several items, but the buyer needs to know which one supports each approved task. Do not assume that a common instrument connector makes all cables or probes interchangeable. The supplier should identify the supported combination and the technical owner should approve its application role.
Preserve the configuration used for the representative demonstration. If a special probe or cable is borrowed for the trial, make its status visible in the final offer. A purchase can fail to deliver the expected capability even when the correct instrument body arrives, simply because a necessary probe or interface was omitted. The equipment list should therefore follow the complete measurement path rather than treating accessories as an informal collection added after the main instrument is selected.
Provide representative construction information
Give the supplier the relevant part description through the authorized application review. Include information the technical owner considers material to the evaluation, such as construction type, accessible surfaces and known variations. Do not assume a demonstration on a generic sandwich panel establishes suitability for every panel in the organization's workload. The buyer should understand what the trial specimen represents and what it does not.
Keep drawings, specimen descriptions and supporting evidence associated with the trial. If proprietary construction information is needed, use the organization's approved sharing arrangements rather than posting it publicly or embedding it in an uncontrolled purchasing worksheet. The procurement file can reference the controlled description. A useful application record allows later reviewers to recognize when a proposed new part differs materially from the one on which the original purchasing decision was based.
Establish the role of reference specimens
Ask the technical owner which reference specimens or comparison artifacts are required for the intended procedure and acceptance trial. Identify who supplies them and what evidence establishes their relevant features. A sample used for product familiarization is not automatically an approved reference for the actual examination. Purchasing should make that distinction explicit in the request and receiving checklist.
Assign each trial or reference item an identity and preserve its documented scope. If a supplier provides a demonstration panel with known features, record how those features are established and what conclusions the trial may support. Do not treat the presence of a visible response as proof of every required detection or characterization claim. The technical owner evaluates the evidence; purchasing ensures that the agreed artifacts and records are available and that substitutions are reviewed rather than silently accepted.
Ask what the saved record contains
The BondMaster product page describes archiving and reporting functions. Ask the supplier to demonstrate exactly what the proposed configuration saves. A screenshot, setup file, measurement trace and report are different artifacts. The technical owner should define which are required for the intended review and customer deliverable.
Open a representative saved project or record on the intended receiving computer. Have the reviewer identify the part, method, probe and relevant configuration. Determine which information is included automatically and which must be entered manually. Do not assume that a visually detailed instrument display guarantees a complete exported record. The procurement requirement is an understandable evidence package that remains usable after the operator has moved on to another component or changed the instrument setup.
Keep instrument presets separate from approved procedures
A product may provide presets or convenient setup functions for common applications. Ask how those functions relate to the organization's controlled procedure and what review is required before use. A preset name should not be treated as authorization to examine every part with a similar description. The technical owner remains responsible for establishing the permitted examination arrangement.
Document the approved setup-management process without publishing operational settings in the buying guide. Ask how saved setups are named, associated with the appropriate part family and distinguished from demonstration or training files. During the trial, verify that the reviewer can identify the setup used for the retained record. This helps prevent an administrative mix-up in which a convenient supplier demonstration file is later mistaken for the organization's approved production configuration.
Preserve the distinction between response and acceptance
An instrument response, an interpretation of that response and a component disposition are separate elements of the record. Ask the technical owner to define how each should appear in the report. A numerical or graphical output does not independently authorize acceptance or rejection of a bonded structure. Purchasing should require a reporting workflow that can preserve the appropriate review decision and its basis.
Use fictional examples that include an item held for further evaluation. Check that the record can distinguish an unresolved result from a completed acceptance decision. If the software offers alarm or classification features, identify their scope and configuration responsibilities. The buyer need not select technical thresholds, but should understand whether the proposed package supports the approved decision process without forcing an operator to assign an unsupported binary outcome merely to complete a report.
Test probe identity and configuration continuity
Ask how the system records the probe identity and relevant configuration when several probes are used during a job. The organization may use different arrangements for different approved tasks, but a later reviewer should be able to determine which produced a particular record. If the software does not preserve all required information automatically, define a controlled external manifest and demonstrate its association with the data.
Include a fictional probe change in the acceptance trial. Confirm that new records do not overwrite the context needed to interpret earlier ones. The technical owner determines what checks or review are required after the change; purchasing verifies that the workflow can retain the resulting evidence. This is particularly important for a kit shared by several users, where the currently connected probe may not be the one used for a previously saved examination.
Evaluate access with the complete probe arrangement
A portable instrument does not establish access at the inspection surface. Ask the supplier to review the actual probe body, cable routing and any supporting arrangement against the intended geometry through the authorized technical process. A probe may have the right measurement mode but still be unsuitable for a confined feature or restricted surface. Preserve the configuration and limitations established by the review.
If a mock-up is used, document how it represents the intended part and what conditions it does not reproduce. Avoid turning one successful access demonstration into a universal coverage statement. The purchasing file should identify the accepted role and any unresolved areas. This allows the organization to plan a supported service and recognize when another probe, method or application evaluation is needed before promising work on a materially different component.
Compare the complete workflow on representative records
Measure the activities needed to produce the agreed deliverable during a controlled trial. Include identification, authorized setup, examination, recording, review and reporting as relevant to the business process. Do not compare only the time to obtain a visible response on a familiar demonstration panel. The complete effort may depend on location documentation and interpretation as much as on the instrument interface.
Record the personnel, accessories and software used. If a specialist prepares the report using tools outside the quote, identify that dependency. A realistic comparison distinguishes observed trial results from estimates for other part families. It does not promise a universal throughput based on a single easy specimen. The purchase should provide a workflow the organization can support with its approved personnel, equipment and reporting arrangements.
Work through a fictional mode-and-cable omission
A hypothetical repair organization requests a package for an approved bond-testing application that requires resonance capability. The quotation lists a familiar instrument family and a general probe kit, while the demonstration uses a multimode unit with an additional cable. During review, the buyer asks for the exact installed model and complete demonstration inventory. The team identifies that the initial offer does not clearly include the necessary mode and interface.
The supplier revises the offer or the technical owner selects another supported package. The buyer obtains a sample record from the final configuration before acceptance. This fictional example does not imply a problem with a named product. It shows why a broad family description can hide two independent omissions: an enabled instrument function and the physical items needed to use it for the intended application.
Plan review access and retained-file support
Confirm the software needed to read saved records and create the required reports. Ask whether the intended review computer and operating environment are supported by the current supplier instructions. Do not assume that a disc or cable listed in an older manual provides a complete modern review arrangement. Obtain the current supported path for the exact instrument and software versions offered.
Test that path with the actual sample files. Preserve the software version and relevant access rights in the acceptance file. If a future firmware change or computer replacement affects record access, route it through the organization's controlled review process. The goal is not indefinite compatibility with every possible system. It is a documented, supported retention plan for the evidence the organization is required to preserve, with dependencies understood before the equipment purchase is closed.
Receive and maintain a bounded package
Reconcile the delivered instrument variant, probes, cables, reference items, software and documents against the accepted offer. Record serial identities where applicable and resolve differences with the responsible owner. The technical acceptance should identify the supported construction and method scope, while the receiving record confirms that the promised items and evidence arrived. Keep those decisions related but distinct.
NDT Connect can coordinate equipment identity, due date, status and notes, but it does not interpret bond-test responses, manage probe-mode configurations or approve composite repairs. Keep technical records in the selected inspection system. Reference the controlled package file from the equipment record where useful. A complete purchasing outcome leaves the organization able to identify the supported application, reproduce the agreed record handover and recognize when a proposed new task needs further review.
Review new constructions before extending the service
A later request may involve a different laminate, core, bonded material or access condition. Compare it with the accepted application statement rather than assuming the existing kit supports it because the instrument has several modes. Ask the technical owner what additional evidence is required and obtain a supplier response for the proposed configuration where appropriate.
Preserve the original scope while recording any approved extension. New application evidence should identify the relevant probe, instrument capability and record requirements. This makes a multimode instrument a useful platform for controlled growth without treating its menu as a list of automatically authorized inspection services. The equipment coordinator can then schedule the right supported package with a clear understanding of its limits.
