Abstract: A corrosion sensor is described. The corrosion sensor comprises a substrate 10 and a patterned conductive layer provided on the substrate 10, wherein the conductive layer defines: a common terminal; a set of terminals, including a first terminal and a second terminal; and a set of sensing elements, including a first sensing element and a second sensing element; wherein respective sensing elements of the set thereof are electrically coupled to the common terminal and to respective terminals of the set thereof, such that the respective terminals of the set thereof are specific to the respective sensing elements of the set thereof.

Abstract: Specimens for evaluating corrosion protection of substrates due, at least in part, to coatings applied thereupon are described. A specimen (1) comprises: a first coating (10), comprising a first set of layers (11) including a first layer (11A), on a first substrate (12); and a first set of perforations (100), including a first perforation (100A) and a second perforation (100B), in the first coating (10), wherein the first perforation (100A) has a first depth D1 through the first coating (10) and a first dimension W1 transverse to the first depth, wherein the second perforation (100B) has a second depth D2 through the first coating (10) and a second dimension transverse to the second depth D2 and wherein the first dimension W1 and the second dimension W2 are different.

Abstract: A sensor (1) and a method of manufacturing the sensor (1), the sensor (1) including a number of metallic strips (5,6,7) mounted on a non-conducting substrate (4) and a module (3) for forming electrical connections to the strips (5,6,7) whereby to enable communication between the strips (5,6,7) and monitoring equipment for the sensor (4), the module including a number of wire connections (16), the method including the steps of encapsulating the wire connections within a flexible chemical and heat resistant sealing compound, and subsequently, encapsulating the flexible sealing compound within a second sealing compound (34) by an injection molding process.
