What is BS EN 12470-1 - Metallic liquid-in-glass thermometers with maximum device about?
BS EN 12470 is a European standard that discusses clinical thermometers. BS EN 12470-1 is the first part of a multi-part series that outlines the performance requirements and test methods for clinical liquid-in-glass thermometers with the maximum device to standardise its performance. BS EN 12470 only applies to thermometers filled with metallic liquid.
Note 1: Note that in some European countries the use of mercury is prohibited in clinical thermometers
Note 2: Substances other than metallic liquids can be used in the manufacturing of liquid-in-glass thermometers. No reference is made to these in this European standard because there is no experience with clinical thermometers which use other substances.
Note 3: BS EN 12470-1 does not apply to clinical thermometers designed for special applications (e.g., thermometers for premature babies, ovulation thermometers) that, owing to their measurement range, scale interval, or maximum permissible error, fall outside the scope of BS EN 12470-1.
Who is BS EN 12470-1 - Metallic liquid-in-glass thermometers with maximum device for?
BS EN 12470-1 on metallic liquid-in-glass thermometers with the maximum device is useful for:
- Manufacturers of clinical thermometers
- Test centres
- Clinics
- Medical laboratories
- Regulatory authorities
Why should you use BS EN 12470-1 - Metallic liquid-in-glass thermometers with maximum device?
A clinical thermometer is used for measuring body temperature that has a constriction in the tube above the bulb preventing movements of the column of liquid downward once it has reached its maximum temperature so that it continues to indicate the maximum temperature until the liquid is shaken back down into the bulb. A maximum device prevents the liquid column from falling when the temperature of the liquid in the bulb returns to the ambient temperature.
BS EN 12470-1 guideline assists you with types of thermometers and requirements on width and length of the scale marks, solid-stem thermometers, enclosed-scale thermometers, resistance to breakage of enclosed-scale thermometers, test methods, and information supplied by the manufacturer for metallic liquid-in-glass thermometers with the maximum device.
With compliance and obedience to BS EN 12470-1, you can standardise the quality of metallic liquid-in-glass thermometers with the maximum device. In addition, ensure the proper functioning of clinical thermometers.
