NDT Procedure Template - Atlantis NDT

A complete, code-compliant NDT written procedure template with all required sections per ASME Section V. Designed for Level III professionals to customize for their specific method, application, and governing codes. Compatible with SNT-TC-1A and ISO 9712 certification schemes.

Every written procedure must include a header block identifying the procedure and its authorization. This section appears on the first page.

Define the boundaries of this procedure. Clearly state what it covers and what it does not cover.

List all codes, standards, and specifications referenced by this procedure. Include edition/year.

List all equipment used in the examination. For each item, specify acceptable makes/models and calibration requirements.

Describe the specific technique parameters. This section must address all mandatory variables listed in the applicable ASME Section V table (e.g., Table T-421 for UT).

Provide step-by-step instructions that a qualified technician can follow to perform the examination.

The examination report shall include, as a minimum, the following information:

Specify the records to be maintained and their retention requirements.

Our Level III professionals develop and qualify custom NDT procedures for your specific applications, codes, and equipment.

Key points covered

List specific material types (e.g., carbon steel, low-alloy steel, stainless steel, aluminum). Reference material specifications (SA-516, SA-106, etc.).
Plate, pipe, castings, forgings, welds (butt, fillet, socket), base metal, clad materials.
Minimum and maximum thickness this procedure has been qualified for (e.g., 6mm to 50mm).
Surface temperature range the procedure is valid for (e.g., 0 to 50 degrees C). If outside ASME default range, procedure re-qualification may be needed.
Cracks, lack of fusion, incomplete penetration, porosity, slag inclusions, laminations, corrosion, erosion.
Butt welds (full penetration), fillet welds, T-joints, corner joints, nozzle welds. Include joint geometry limitations.
State what this procedure does NOT cover (e.g., austenitic welds, dissimilar metal welds, HDPE pipe).
State the minimum certification level (e.g., Level II minimum for performing examinations and interpreting results; Level III for procedure approval and training).
ASNT SNT-TC-1A (employer-based), ASNT Central Certification (ACCP), ISO 9712, PCN, or other. Reference the company Written Practice.
Near vision acuity: Jaeger J1 or equivalent at 12 inches minimum, annually. Color perception test (where applicable) for distinguishing contrasts. Natural or corrected vision.
Minimum training hours per SNT-TC-1A recommended practice or applicable scheme. Method-specific and technique-specific training.
OJT hours required per certification level and method per SNT-TC-1A or applicable scheme.
Required surface condition (e.g., weld cap ground flush, minimum surface finish, paint removal width)
Cleaning methods (wire brush, grinding, solvent cleaning, chemical cleaning)
Scan pattern: raster, zigzag, or encoded; overlap percentage; scan index (increment)
Beam angles and directions (for angled techniques, list all angles to be used)
Coverage requirements: 100% volumetric, specific zones, or sampling plan
Instrument settings: gain, range, velocity, reject/suppress level, gate positions
Transfer correction method (if applicable -- e.g., UT coupling differences)
Multi-technique requirements (e.g., 0-degree + angle beam for complete coverage)
Special technique considerations (TOFD, phased array, encoded scanning)
Reference standard description: material, dimensions, reflector type/size
Scanning sensitivity: how much above reference level (e.g., 6 dB above DAC)
Evaluation level: at what signal amplitude indications require characterization
Calibration verification frequency: at start, every 2 hours or less, end of shift, after equipment change
Calibration invalidation criteria: what constitutes loss of calibration
Action when calibration is lost: re-examine all work since last valid calibration check
Component identification (equipment number, weld joint number, drawing reference)
