Malm

 

(the name “malm” is given by English stonemasons to soft clayey oolite limestones), in geology, the uppermost division of the Jurassic system. The term was proposed by the German geologist A. Oppel in 1856-58. The Malm is subdivided into four stages: Callovian, Oxfordian, Kimmeridgian, and Upper Volgian (the last is called the Portlandian or Tithonian in different countries). A number of West European geologists classify the Callovian in the Middle Jurassic. The accumulation of marine deposits in the Malm was associated with a vast transgression. Limestone and flysch strata are especially typical of the Malm. In the USSR it is extensively developed on the Eastern European Platform, in Western Siberia, the Caucasus, the Crimea, and the Pamirs.

On the TMS stand at Munich the MALMS range of photometric test equipment will be available to view including MALMS Mobile and MALMS Photometric Bench Tester as well as the M-Torque system that allows each AGL location to be identified by a RFID tag with a name, number, make and GPS location.
In addition to MALMS Mobile, TMS also offers MALMS Workshop and MALMS PhotoBench systems, which allows the airport to measure unserviceable fixtures removed from the airfield and then repair fixtures prior to use on the airfield in the maintenance workshop.
In Europe, airports such as Amsterdam Schiphol, Copenhagen and Athens are regular users of MALMS, while further afield Kuala Lumpur, Sydney, Abu Dhabi and Phoenix Sky Harbor use MALMS to confirm their ALL serviceability levels.
At present, TMS is supplying MALMS systems to Delhi, Leeds Bradford and Prague International airports, In the UK, Europe, USA and Australia, TMS is supplying AGL photometric measurement services, either directly or through licensed partners.
Essentially, the MALMS Differential Maintenance strategy, and associated technology, takes into account all the variable factors that have been found to contribute to light fitting performance deterioration, and so significantly improves the effectiveness and efficiency of maintenance activity," states Vernon Taylor.
More importantly, those employing MALMS as part of a preventative maintenance strategy have seen the effectiveness of their maintenance improve to a point where their core AGL services are now constantly maintained to a verifiable performance that can exceed the levels set by the regulatory authorities.
Using the MALMS system, a commissioning run was undertaken to determine the new AGL's compliance, and this discovered a number of alignment issues.
He adds: "We are also starting to use the data from the MALMS system to monitor the performance of various fittings over time and investigate life-cycle costs.
