Applicable Codes, Standards and References

The work may be designed or performed with reference to the following, as applicable to the agreed scope:

1.    ASME, ASTM, API and AWS requirements

2.    ISO, EN, BS and IIW technical references

3. ASNT, ISO 9712, employer written practices and training-scheme requirements

4.    NAS 410, EN 4179 and customer/OEM requirements where relevant

5.    Asset-owner specifications, approved drawings and project procedures

The customer should identify the exact document and revision. Reference to a standard does not by itself constitute certification, accreditation or approval by the issuing body.

Project Workflow

1.    Requirement review: Review the application, method, component, material, geometry, equipment and intended use.

2.  Technical definition: Confirm the drawing, flaw or reflector schedule, tolerances, access and documentation requirements.

3.    Design approval: Issue the proposed layout or technical basis for customer approval before manufacturing or modification.

4.    Manufacturing or service execution: Complete fabrication, machining, flaw introduction, marking, inspection or refurbishment under controlled instructions.

5.    Verification: Check the agreed dimensions, reflector locations, identification and NDT responses using suitable methods.

6.    Documentation and delivery: Compile the agreed records, protect the items and arrange domestic or international dispatch.

Documentation and Deliverables

Depending on the agreed scope, the deliverable package may include:

1.    Approved drawing or technical layout

2.    Material and component information, where included

3.    Flaw or reflector schedule and location map

4.    Dimensional inspection record

5.    NDT verification record, where included

6.    Unique identification and engraving details

7.    Photographic record

8.    Certificate of conformity for the agreed manufacturing or service scope

9.    Confidential master flaw record for blind specimens

10.Packing, preservation and handling information

Technical Limitations and Responsibilities

1.    Only the responsible certification or employer authority can approve the final examination scheme and scoring criteria.

2.    Blind security is compromised if candidates obtain the master flaw map or prior scan data.

3.    Manufacturing feasibility and achievable tolerances depend on material, geometry, access, flaw type and verification method.

4.    Final use, acceptance and authorization remain the responsibility of the customer and the applicable competent authority.

Frequently Asked Questions

Can this service be customized for our component and NDT procedure?

Yes. The design is reviewed against the supplied component geometry, material, inspection method, equipment configuration and intended use before the scope is finalized.

Can customer-supplied material or components be used?

Yes, subject to review of material identity, dimensions, condition, available quantity and suitability for the required manufacturing or modification process.

Can the specimen or record be supplied as a blind item?

Yes. Neutral identification can be applied and the detailed master information can be released separately to an authorized coordinator.

Can the work be based on an international code or standard?

Yes. It can be designed or performed with reference to the customer-specified code, standard, drawing or procedure. The applicable edition and acceptance basis must be confirmed.

Do you support international customers?

Yes. Domestic and international supply can be arranged, subject to packing, logistics, customs and any material or regulatory restrictions.
