Kirti NDT & Engineering Services provides the AWS-DS Test Block, a calibration standard designed for shearwave distance and sensitivity checks in ultrasonic testing. The block’s dimensions are fixed at 6.000" x 4.000" x 2.000" (152.4 mm x 101.6 mm x 50.8 mm), with a 2.0" high central section flanked by two 4.0" sections, conforming to AWS requirements. This design allows the block to serve dual purposes: longitudinal wave calibration and shearwave sensitivity adjustments, making it a versatile tool for NDT labs.
The block is available in three materials: aluminium, carbon steel and stainless steel, each selected to match the acoustic properties of common test specimens. Aluminium blocks offer lightweight handling and are ideal for aerospace applications, while carbon steel and stainless steel variants replicate the acoustic impedance of ferritic and austenitic steels, respectively. AWS does not specify a separate metric version, so the same block design satisfies both inch and metric calibration needs without modification.
Industries such as oil and gas, power generation and aerospace use the AWS-DS block for routine calibration of ultrasonic flaw detectors and probes. Buyers typically source these blocks in single or small batch quantities, as they are reference standards rather than consumables. Importers should confirm the material grade (e.g., 6061 aluminium, ASTM A36 carbon steel or 304/316 stainless steel) and surface finish, as these affect the block’s acoustic performance and durability.

Kirti NDT & Engineering Services is based in Dombivali, Thane, Maharashtra, with its office at 707/B-Wing, Shree Sai Raj Park, Rajaji Path Road. The company specializes in non-destructive testing (NDT) equipment and calibration tools, catering to industries where material integrity is critical. The harbor trust tier indicates a baseline verification level, but the profile does not disclose response rates, certifications or production details.
The listing focuses solely on the AWS-DS Test Block, without additional claims about the supplier’s manufacturing capabilities or quality systems. Buyers should confirm whether Kirti NDT & Engineering Services produces the blocks in-house or sources them from a third party. For calibration blocks, traceability to national standards (e.g., NIST or equivalent) is essential, so request certification documents to validate the block’s compliance with AWS requirements.

Before ordering, confirm the material grade and surface finish of the AWS-DS block, as these directly impact its acoustic performance. Request a certificate of conformance to AWS specifications and traceability to national standards to ensure the block’s suitability for calibration. If your application requires specific material properties (e.g., corrosion resistance for stainless steel), verify the exact alloy grade and heat treatment process used.
Logistics for the AWS-DS block typically involve smaller, high-value shipments, so discuss packaging options to prevent damage during transit. Confirm the supplier’s nearest port (likely Mumbai or Nhava Sheva) and whether they offer air freight for urgent deliveries. Clarify Incoterms (e.g., FOB or CIF) and payment terms, as these are not specified in the listing. For international buyers, ensure the supplier can provide the necessary export documentation, including a commercial invoice and packing list.
Upon receipt, inspect the block for dimensional accuracy using a calibrated micrometer or CMM to verify the 6.000" x 4.000" x 2.000" dimensions. Check the surface finish for scratches or irregularities that could affect ultrasonic reflections. For long-term use, store the block in a controlled environment to prevent corrosion or deformation. Periodically recalibrate the block against a primary standard to maintain its accuracy over time.
