Scales in the health sector

Measurement results are important in the health sector. Weight and other measurements form the basis for further treatment of patients and for health checks, as well as in connection with mapping and counselling in public health, nutrition and physical activity.

Trust in correct measurements is important both for the individual and for health professionals.

In the health sector, scales are used in several contexts, including:

  • child health clinics and school health services
  • medical practices and doctors’ surgeries
  • hospitals
  • pharmacies
  • the pharmaceutical industry

Requirements have been established for the use of personal scales employed to determine mass in medical practice when weighing patients for the purpose of monitoring, diagnosis and medical treatment.

The following provisions apply specifically to medical scales:

  • To determine mass in medical practice when weighing patients for the purpose of monitoring, diagnosis and medical treatment, class III scales, or more accurate scales, must be used. For personal scales, class IIII scales are permitted.
  • To determine mass in the preparation of prescription medicines in pharmacies, and to determine mass in analyses carried out in medical and pharmaceutical laboratories, class II scales, or more accurate scales, must be used. New scales must undergo conformity assessment in accordance with the applicable directives, and the supplier must provide a declaration of conformity.

It is recommended that regular self-checks of the scale be carried out. A self-check may be performed by verifying that the scale is zeroed and placed on a flat and stable surface. Lack of zeroing is a fairly common error, but one that can easily be avoided. The zero button on the scale is most often found on the display and is marked with the symbol >0<. In addition, adjustment of the scale can be verified using standardised weights.

The Norwegian Metrology Service inspects medical scales on request or in connection with market surveillance. See our services ⬇️
