BS 2648:1955

This standard BS 2648:1955 Performance requirements for electrically-heated laboratory drying ovens is classified in these ICS categories:

• 71.040.10 Chemical laboratories. Laboratory equipment

This British Standard specifies the performance requirements of electrically-heated laboratory ovens of the type used for the determination of moisture by drying within the temperature range 95 °C to 110 °C, and having external provision for manual adjustment to any desired temperature within that range. Ovens having a wider temperature range are not excluded provided they comply with the other requirements of this standard.

The standard applies to ovens with an internal space of about 1 to 3 cu. ft which are ventilated by convection, whether or not they are fitted with internal fans to assist the circulation of air; it does not apply to vacuum ovens or to forced draught ovens.

Limits and test methods for temperature variation, fluctuation, drift and overshot, ventilation rate, for ovens for moisture determination by drying wiithin range 95°C to 110°C. Ovens about 1 to 3 cu ft internal space ventilated by convection, with or without fans; vacuum or forced draught ovens not covered.
