PH Tool V1 (A2) Test Block BS 2704

Part # PHTV1A1TBBS2704 Category

For calibrating ultrasonic flaw detection equipment in both laboratory and on-site conditions.

Our version of this block includes a 100mm radius, 1.5mm and 50.0mm holes, engraved reference mark scales, and two optional slots at the zero point which provide calibrating signals at intervals of 100mm range. In accordance with British Standard BS 2704 Block A2 Mod. 1, German Standard DIN 54-120, Australian Standard AS 2803, and ISO 2400. Also meets the requirements of the Dassault Aviation Falcon 10 Mandatory Service Bulletin #294 dated March 20, 2002.
This block is not to be confused with the new EN 12223/ ISO 2400 Calibration Block No. 1 (also called the K1 block,) which is similar but contains a 3.0mm through-hole rather than a 1.5mm hole. See our test block store for this block.
