| — | they can be from different classes. The class of a manometer is the precision of a reading compared to a full-scale reading expressed as a percentage (e.g. manometer 1 000 kPa class 1 signifies the maximum useable pressure 1 000 kPa, reading at ± 10 kPa). Class 1 is recommended for precise measurements. |

Class 1 is recommended for precise measurements.

3.   PROCEDURE

Measurements must be carried out on bottles where the temperature has stabilised for at least 24 hours. After piercing the crown, the cork or plastic stopper, the bottle must be shaken vigorously to reach a constant pressure, in order to take a reading.

3.1.   Bottles with capsules

Slip the clamp over the spur binders under the ring of the bottle. Tighten the nut until the entire apparatus is tight on the bottle. The top part is screwed onto the nut. To avoid any gas escaping, the capsule should be pierced as quickly as possible to bring the joint into contact with the capsule. The bottle must be shaken vigorously until it reached a constant pressure, when a reading can be taken.

3.2.   Bottles with corks

Place a point at the end of the needle. Position this on the cork. Tighten the four screws on the cork. Tighten top part (the needle goes through the cork). The point must fall into the bottle so that the pressure can be transmitted to the manometer. Take a reading after shaking the bottle until it reaches a constant pressure. Retrieve the point after taking the reading.

4.   EXPRESSION OF RESULTS

The excess pressure at 20 °C (Paph20) is expressed in pascals (Pa) or kilopascals (kPa). This must be in accordance with the precision of the manometer (e.g. 6,3 × 105 Pa or 630 kPa and not 6,33 × 105 Pa or 633 kPa for a class 1 manometer with a full-scale reading of 1 000 kPa).

When the measure of temperature is other than 20 °C, this must be corrected by multiplying the pressure measured by an appropriate coefficient (see Table 1).

5.   CONTROLLING THE RESULTS

Method of direct determination of physical parameters (Type I criteria method)

Checking the aphrometers

Aphrometers must be checked regularly (at least once a year).

This is done using a calibration bench. This allows the manometer for testing to be compared with a high-quality reference manometer measured by national standards, mounted in parallel. The check compares the values indicated by the two apparatuses for rising, and then falling, levels of pressure. If there is a difference, the manometer can be regulated using an adjustment screw.

Laboratories and authorised organisations are all equipped with calibration benches; they are also available from manometer manufacturers.’
