Examples of these requirements include the need to check that an instrument is being used within the stated environmental conditions and application restrictions of the manufacturer. Specific requirements are made to check for compatible materials whenever any part in a safety instrumented function has process wetted parts. A planned comprehensive testing program with written test results is required. A periodic inspection and test plan must be created and verified. 

The determination of wearing is carried out according to CEN EN 12274-5 (2003). The test method determines the minimum binder content of the mix under wet track abrasion conditions. It also covers the compatibility between aggregate fillers and cationic bitumen emulsion. The test is similar to wet track abrasion loss described in ASTM D 3910 (2011), a brief description of which is given in Section 6.8.3.1. 

Two approaches have been adopted for pC02 sensing, namely (1) wet sensors and (2) plastic (solid-state) sensors. A wet sensor consists of a pH-sensitive probe dissolved in aqueous bicarbonate buffer solution, which is separated from the gaseous or liquid test medium by a gas-permeable membrane [9]. In plastic sensors, a polar pH-probe is immobilised in a thin polymer film. The probe is usually ion-paired with a lipophilic base such as a tetra-alkyl ammonium hydroxide. This ion-pair combination facilitates compatibility between the two components, whilst simultaneously eliminating the need for aqueous buffers due to the associated water of hydration. This makes it possible for these sensors to maintain their sensitivity to CO2, although they may show some humidity dependence. The requisites of a CO2 probe are a suitable a significant change in absorption or emission characteristics upon...
