Corrosiveness to Copper from LPGs (ASTM D1838)

Main Characteristics
The TB30 bath is designed to cover the detection of the corrosiveness to copper of liquified petroleum gases conforming to ASTM D1838, IP411, and ISO 6251. A test involves the immersion of a polished copper strip in approximately 100mL of the sample. The sample is exposed at a temperature of 37.8°C (100°F) for one hour in a cylinder of suitable working pressure. At the end of this period, the copper strip is removed and rated as one of the four classifications of the ASTM Copper Corrosion Standard. The TB30 is specifically designed to hold a temperature stable at 37.8°C without the use of an external circulator. The bath is deep enough to accommodate two corrosion test cylinders in an upright position. The corrosion test cylinder is also manufactured by Tamson. The cylinder is supplied with a works certificate that the cylinder is tested to withstand a minimum hydrostatic test pressure of 6900 kPa (1000 psig) and that no leak was found when tested at 3450 kPa (500 psig) with gas. Stainless steel bath, 304, PTFE.

Accuracy
The insulation of the bath and electronic design result in a stable working temperature of ±0.02°. The set point can be set in steps of 0.1° in the range of 0°C up to 80°C (33.8 to 176°F). The accuracy on the display is displayed in 0.1°C. Temperature range of the TB30 is from ambient up to +80°C (176°F). Standard temperature readout available in °C, on request in °F.

Safety
The bath conforms to CE regulation. It is further equipped with a mechanical resettable safety thermostat.
