Complies to following International Standard:
ASTM D5
Test Objective:
The test objective is to evaluate the hardness/firmness of Soap using a Needle according to ASTM methods. A standard needle is released from a Penetrometer and allowed to drop freely into the sample for 5 seconds (or a different specified interval) at constant temperature.
Silent Features:
- Compact design and rugged construction ensures long service life and facilitates transport for field applications.
 - Sturdy cast iron base provides excellent support.
 - Built‑in spirit level and leveling screws ensure proper alignment during testing.
 - Supplied with Needle (2.5 gm), weight (50 gm) and Digital time controller
 
Brief construction details:
- The apparatus consists of a cast aluminum base with an iron stand on which moves an aluminum arm.
 - A 6" dial is fixed on this arm and a brass chromium plated rod slide through the lower portion of the arm.
 - A Needle with plunger is fitted to this rod.
 - The dial is graduated from 0‑400 in one tenth millimeter sub division.
 - Weight of the Needle and plunger match the criteria of ASTM requirements.
 - The base of the instrument is also user ‑ adjustable.
 - It can be lifted up or down with the jack provided at the bottom.
 - The penetration time is controlled and indicated on Digital Timer Panel with least count of 0.1 second.
 - The automatic digital timer and electrical arrangement, which on push of a button, automatically releases the plunger with Needle by a magnetic device.
 - The penetration value is measured and indicated on dial gauge.
 - Dial Gauge measures the penetration distance in 1/10th mm accuracy.
