IMPORTANCE OF CALIBRATION AND TRACEABILITY
Service Overview
Calibration and traceability provide a documented basis for
confidence in NDT measurements, reference standards and inspection-system
performance. Properly controlled equipment and reference items help improve
repeatability, identify drift and demonstrate that measurements are linked to
known values or agreed reference features.
Scope of Service
1. Maintain
unique identification for instruments, blocks and reference specimens.
2. Use
calibrated measuring equipment for critical dimensional checks.
3. Define
calibration intervals according to quality-system and equipment requirements.
4. Record
calibration status, due dates and relevant certificate information.
5. Maintain
traceability between drawings, material records, manufacturing records and
final identification.
Available Specimen and Component Configurations
1.
Ultrasonic calibration blocks.
2. Eddy
current reference standards.
3. Tube
standards and corrosion blocks.
4.
Dimensional gauges and reference artefacts.
5. Flawed
training specimens with controlled master records.
Flaws, Reflectors or Conditions Covered
1. Known
machined reflectors used as calibration references.
2.
Controlled dimensions such as FBH, SDH, notches, holes and wall-loss
depths.
3. Natural
flaws characterised for training or comparison where appropriate.
4.
Identification and location features used to maintain specimen
traceability.
Supported NDT Methods
The product, specimen or service can support the following
NDT methods where technically applicable. Final suitability is confirmed
against the material, geometry, target condition and intended equipment
configuration.
1. UT,
PAUT, TOFD and advanced ultrasonics.
2. ECT/ECA
and tube electromagnetic methods.
3. MT, PT,
VT and radiographic quality-control systems.
4.
Dimensional verification supporting NDT reference-standard manufacture.
Typical Applications
1.
Instrument setup and verification.
2.
Quality-system audits.
3. Training
and personnel assessment.
4.
Procedure validation and repeatability studies.
5.
Inter-laboratory or equipment comparison activities.
Industries Served
1. NDT
laboratories and service companies.
2.
Aerospace, oil and gas, power and manufacturing.
3.
Calibration and metrology laboratories.
4. Training
centres and certification programmes.
5. Research
and product-development organisations.
Applicable Codes, Standards and References
The work may be designed, manufactured or performed with
reference to the following, as applicable to the agreed scope:
1. ISO/IEC
17025 concepts where calibration or testing laboratory controls are applicable.
2. ISO 9001
quality-management requirements where adopted.
3.
Applicable ASTM, ASME, ISO, EN and customer procedures.
4. National
or international metrology traceability requirements where relevant.
The customer should identify the exact document, edition 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 drawings,
dimensions, flaw or reflector schedule, tolerances, access and documentation
requirements.
3. Design Approval: Issue the proposed
technical basis or layout for customer review where custom manufacture is
required.
4. Manufacturing or Service Execution:
Complete fabrication, machining, flaw introduction, marking, inspection or
preparation under controlled instructions.
5. Verification: Check agreed dimensions,
identification, reflector locations and relevant NDT responses using suitable
methods.
6. Documentation and Delivery: Compile
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, where applicable.
2. Material
and component information, where included.
3. Flaw,
reflector or reference-feature schedule and location map.
4.
Dimensional inspection record.
5. NDT
verification record, where included.
6. Unique
identification, engraving or labelling details.
7.
Photographic record where requested.
8.
Certificate of conformity for the agreed manufacturing or service scope.
9. Packing,
preservation and handling information.

for conventional and advanced NDT methods where technically applicable.
3.
Controlled machining, flaw introduction, identification and custom
fabrication capabilities.
4. Open,
blind and partially blind documentation options for training and assessment
programmes.
5.
Traceable drawings, flaw maps, dimensional records and verification
information when included in the scope.
6. Support
for domestic and international customers, subject to logistics and applicable
restrictions.
Information Required for a Technical and Commercial Proposal
1. Item to
be calibrated or verified.
2. Required
measurement range and tolerance.
3.
Applicable calibration or inspection procedure.
4.
Reference standard identification and traceability requirements.
5. Required
certificate or report format.
6.
Acceptance criteria and due date.
7. Quantity
and delivery schedule.
Technical Limitations and Responsibilities
1.
Traceability does not automatically mean accreditation.
2.
Calibration validity depends on the defined scope, interval,
environmental conditions and measurement uncertainty.
3.
Reference blocks can wear or be damaged and should be periodically
checked.
4.
Calibration certificates must be reviewed against the exact measurement
requirement.
5. Formal
accredited calibration must be performed by an appropriately accredited
facility when specifically required.
Frequently Asked Questions
What is traceability in NDT?
Traceability is the documented link between an item, its
identification, measurements, calibration records and relevant reference
information.
Does a certificate of conformity replace a calibration certificate?
No. A conformity certificate confirms the agreed
manufacturing or service scope; a calibration certificate addresses specific
measured quantities and calibration results.
How often should a reference block be checked?
The interval should be defined by the user's quality system,
frequency of use, risk, damage history and applicable procedure.
Can you supply dimensional inspection records?
Yes, dimensional records can be included for agreed critical
features.
Does traceability mean the product is accredited?
No. Accreditation applies to organisations and defined
scopes; it should not be implied merely because traceable records are provided.
