ARDROX 9812, ARDROX 9813 and ARDROX 9814 are fluorescent penetrants of three different

sensitivities, to be used with a separate emulsifier. They are qualified to AMS 2644.

These penetrants give crisp indications with exceptionally low levels of background and have

excellent heat and UV fade characteristics. They are ideal for electrostatic application.

They are normally used in conjunction with dilute (10% v/v) ARDROX 9881 hydrophilic emulsifier and

ARDROX 9D4A dry powder developer.

ARDROX 9812, ARDROX 9813 and ARDROX 9814 are used to inspect metal components during

manufacture and overhaul. They can be classified as follows:

ARDROX 9812 – medium sensitivity;

ARDROX 9813 - high sensitivity;

ARDROX 9814 - ultra high sensitivity.

Approvals

ARDROX 9812, ARDROX 9813 and ARDROX 9814 are approved to AMS 2644 at the following

levels:

ARDROX 9812 – level 2.

ARDROX 9813 – level 3.

ARDROX 9814 – level 4.

Chemicals required

ARDROX 9812, 9813, 9814 [fluorescent penetrant]

ARDROX 9881 [penetrant remover]

ARDROX 9D4A [powder developer]

Method of use

ARDROX 9812, ARDROX 9813 and ARDROX 9814 may be applied by brushing, tank immersion or

by electrostatic spraying. The following typical process sequence illustrates the recommended

method of use for general industrial applications. However, where relevant, the process specifications

of the approving authorities must be closely followed.
