FOMA FILM
INDUX R5 is an industrial radiographic film intended for non - destructive material testing using X- or gamma radiation. INDUX R5 is a standard-speed, high-contrast, very fine-grain film suitable for radiography with or without lead scr eens. It is an ideal film for most standard applications. INDUX R5 corresponds with the class C4 classification according to EN 584-1 standard and according to ASTME 1815 standard with class I.
 
 
Applications
INDUX R5 is suitable for the radiography of welds and medium-walled steel or thick-walled light metal parts/ products.

Other sizes are subject to be agreed with the manufacturer.
MultiPack – daily package containing 2 films INDUX with various speeds.
Dimensions and speeds of inserted films according to customer‘s individual requirements.
Film base
INDUX R5 is manufactured on a dimensionally stable bluish polyester base of 0,175 mm thickness.
Screens
Screens-packed kinds (FOMAPAK) content lead screens 0,025 mm thick, backed by a paper of 70 - 90 g/sq. m of basis weight, on both film sides.
Darkroom illumination
INDUX R5 should be handled and processed under indirect safelight illumination with a wavelength over 520 nm.
Recommended are safelight filters Agfa R1 filter (dark red) or Agfa G7 filter (olive-green) in a safelight lamp with a 25 watt bulb and placed in a distance of minimum 75 cm between the reflective surface and the film, or LED light sources with a wavelength of 660 nm or 590 nm.

Processing
INDUX R5 is intended both for the manual and automatic processing.
Recommended chemicals for the manual processing:
FOMADUX LP-T Developer and Developer-Replenisher (5 minutes of developing time at 20 oC, 1 + 3)
FOMAFIX Rapid Fixer
Recommended chemicals for the automatic processing:
FOMADUX LP-D Developer-Replenisher (2 minutes of developer immersion time at 28 oC)
FOMA LP-DS Developer Starter
FOMAFIX + FOMAFIX H Hardening Rapid Fixer.
INDUX R5 can also be processed in corresponding processing chemicals of other manufacturers, for example developer Agfa G135 for automatic processing 2 minutes of developer immersion time at 28 oC or G128 for manual processing 5 minutes of developing time at 20 oC.

Archiving of processed films
The manufacturer guarantees the archival permanence of mi - nimum 50 years when complying with conditions following:
– films must be perfectly fixed and washed
– films must be stored at a relative humidity of 30 to 60% out
of reach of harmful gases.
Storage of unexposed films
Unexposed films should be stored in the original packaging in a cool, dry place (temperature ranging from 5 to 21 oC, relative humidity from 40 to 60 %), out of reach of harmful vapours, gases and ionizing radiations. Films stored in a refrigerator and a freezer should be acclimatized to room temperature for approx. 2 and approx. 6 hours respectively. Exposed films should be processed as soon as possible
