The '''Proof and Experimental Establishment''' ('''PXE''') is an [[India]]n defence laboratory of the [[Defence Research and Development Organisation]] (DRDO). Located in [[Balasore]], [[Orissa, India|Orissa]], [[India]]. its main purpose concerns the research and development of technologies and products in the area of medium and large caliber weapons and their ammunition. PXE is organised under the Armament and Combat Engineering Cluster of DRDO.

== History ==

In March 1894, the first proof testing in India was carried out, with there being fired six inch (152 mm) Bag Loader Howitzers and 12 Pounder Shrapnel shells under the command of Captain R.H. Mahon. He recommended the creation of a dedicated department for this purpose. The Proof Department in India was sanctioned in May 1895.<ref name="History">[http://www.drdo.org/labs/arma/pxe/history.shtml History of PXE] {{webarchive |url=https://web.archive.org/web/20061009025450/http://www.drdo.org/labs/arma/pxe/history.shtml |date=9 October 2006 }}</ref> It was established on 7 November 1895, with headquarters at [[Balasore]] and Lt. R.T. Moorre as the head.<ref name="PIB">{{cite news | title = ISO certificate for Proof and Experimental Establishment, Chandipur | url = http://pib.nic.in/archieve/lreleng/lyr2002/rdec2002/18122002/r1812200235.html | work = [[Ministry of Defence (India)|Ministry of Defence]] Press Release | publisher = [[Government of India]] Press Information Bureau | date = 18 December 2002 | accessdate = 2007-11-15 }}</ref>

Later, the establishment was renamed to the '''Proof & Experimental Department''', and later still was renamed as PXE. The establishment was organised under the [[Ordnance Factory Board|Directorate General of Ordnance Factories (DGOF)]], India and subsequently came under the supervision of the Inspection Organisation under the DGOF. After Independence, PXE was under the administrative control of DGI up to 1958. On 15 July 1947, Lt. Col. B.N. Mitra became the first Indian to head the organisation. The establishment was brought under the administrative control of the DRDO in October 1958.

== Areas of work ==

PXE is the main non-[[Indian Army|Army]] [[Proving ground]] and research establishment for design and developmental trials of guns, mortars, rockets, RCL, tank guns and their ammunition, including Naval guns and ammunition.<ref>[http://www.drdo.org/labs/arma/pxe/areas.shtml PXE Areas of Work] {{webarchive |url=https://web.archive.org/web/20061009025411/http://www.drdo.org/labs/arma/pxe/areas.shtml |date=9 October 2006 }}</ref> It also conducts technical evaluation trials for imported weapons and ammunition as well as R&A trials for compilation of Range Tables.

PXE also conducts performance evaluation trials for [[Vehicle armour|tank armour]] and ammunition, as well as proof of armour plates, tank turrets, ICVs, proximity fuzes, etc. and also weapons and ammunition produced by the [[Indian Ordnance Factories]]. PXE has conducted tests of the [[Arjun MBT]] Armour<ref name="FI Arjun">{{cite news |first=Chacko P. |last=Joseph |author-link=Frontier India |title=Dissimilar Combat: Arjun MBT Vs T-90S specs |url=http://frontierindia.net/dissimilar-combat-arjun-mbt-vs-t-90s-specs/ |publisher=[[Frontier India Defence and Strategic News Service]] |date=30 May 2007 |accessdate=2007-11-15 |quote=In January 2000 at Proof & Experimental Establishment (PXE), Balasore, Arjun tank armor defeated all available HESH and FSAPDS rounds including Israeli FSAPDS rounds. |url-status=dead |archive-url=https://web.archive.org/web/20071126105340/http://frontierindia.net/dissimilar-combat-arjun-mbt-vs-t-90s-specs/ |archive-date=2007-11-26 }}</ref> as well as tests of indigenous [[Explosive reactive armour]]. The lab has also conducted tests of other armaments such as the Indian Field Gun and the [[Pinaka Multi Barrel Rocket Launcher]] System.<ref name="PIB"/>

PXE also conducts comparative propellant and ballistics parameters testing and is involved in the establishment of propellant standards, in their periodical check firing and in [[Quality Assurance]] through periodic checks of ammunition that are held in Army and Naval Depots.

=== Facilities ===

The PXE operates large test ranges. The establishment's initial land area was about {{convert|15|acre|m2|adj=on}}, that area increasing to {{convert|685|acre|km2|adj=on}} when the range was increased in 1949 [https://web.archive.org/web/20071123071839/http://www.cubicao.tk/proof.html]. The establishment has grown in size, in accordance with its changing role over the years. With the increased range of missiles and ordnance being tested, the test ranges have also been expanded. At present, the establishment has a notified range of 50 km in length along the sea coast and 50 km into the sea.<ref name="History"/> The Range is a natural sea-based range with oscillating tide conditions. During low tide, water recedes to a distance of about 3 km into the sea beach, thus facilitating various range operations.<ref>[http://www.drdo.org/labs/arma/pxe/facility.shtml PXE Facilities] {{webarchive |url=https://web.archive.org/web/20071208230619/http://www.drdo.org/labs/arma/pxe/facility.shtml |date=8 December 2007 }}</ref>

PXE also has test facilities for the measurement of range and accuracy of rockets and projectiles, measurement of armor protection levels, and testing of [[proximity fuze]]s. PXE also has labs to measure the ballistic characteristics - [[Internal ballistics|Internal]], [[External ballistics|External]] and [[Terminal ballistics]].

== Projects and products ==

PXE is an [[International Organization for Standardization|ISO]] 9001:2008 certified Organisation.<ref name="PIB"/> Some Achievements of PXE include:<ref>[http://www.drdo.org/labs/arma/pxe/achieve.shtml PXE Achievements] {{webarchive |url=https://web.archive.org/web/20061009025350/http://www.drdo.org/labs/arma/pxe/achieve.shtml |date=9 October 2006 }}</ref>
