Community and national rules and regulations and directives are a set of laws of performance required, that any products/services marketed within the EU countries must respect.
The technical standards instead define the requirements that the manufacturer should apply in their products and services with voluntary nature, to obtain compliance.
NB: ITALMANOMETRI RESPECTS BOTH DIRECTIVES/REGULATIONS THAT STANDARDS OF GOOD PRACTICE.
According to the Directive 2014/68/UE del 2014.05.15, pressure gauges are classified as pressure accessories and in order to determine whether the CE symbol is required the following criteria
must be evaluated:
– Bottom full scale pressure.
– Internal volume.
– Types of fluids for which pressure gauge is projected.
Characteristics of Italmanometri’s pressure gauges are the following:
– Pressure of bottom scale: from -1 bar until 1,000 bars.
– Internal volume: < 0.1 l.
– Types of fluids for which pressure gauge is designed: liquids and gas.
According to the Directive, our pressure gauges are not subject to obligatory CE marking and have to be designed and manufactured complying with current EU Countries technology rules aiming to
guarantee safety during operation.
Exception: all pressure gauges designed to control pressure of dangerous gasses listed in Directive 67/548/EC are subject to obligatory CE marking if their bottom scale pressure doesn’t exceed
HARMONISED STANDARDS OF GOOD PRACTICE
Bourdon tube pressure gauges. Dimensions, metrology and assay. Aim and application field: this European regulation defines the requirements of pressure, vacuum and compound gauges with Bourdon tube circular, spiral or helical indicators, of nominal dimensions between 40 and 250, used for the measurement of relative pressures until 1,600 bars.
Recommendations for choosing and installing a pressure gauge.
Membrane and capsule pressure gauges. Dimensions, metrology, requirements and assay
EN 837 or UNI EN ISO 5171: 2010
Pressure gauges used in soldering, cutting and similar processes.
Object and application field: this European regulation defines requirements of Bourdon type pressure gauges used in soldering, cutting and similar processes for measuring compressed gas pressure up to 300 bars, melted acetylene and liquefied gas pressure.
In all above cases, U.E. Directives or Regulations will be printed on the device, either with the CE symbol (in case of U.E. Directives) or by indicating the Regulation number (for example EN-837 or UNI EN ISO 5171).
PED DIRECTIVES (Pressure Equipment Directive)
European Directives regulating pressure measurement instruments became effective as of 30.05.2002. Here is a summary of the instructions for this purpose:
Pressure gauges with bottom scale values exceeding 0.5 bar, being maximum pressure components, must comply with DGRL A.2014/68/UE 2014.05.15 PeA (regulations for pressure instruments)
and related requirements.
As their use conditions are not completely known, we design and manufacture our pressure gauges according to the most rigorous rules (class I gas). That means that our pressure gauges are marked
with the CE symbol starting from bottom scale value of 200 bars, according to conformity procedures. Pressure gauges with connection flanges exceeding DN 25, starting from bottom scale value of 0.5 bar are also marked with the CE symbol.
The CE symbol is shown on the external part of the package.
A Conformity Certificate is issued on request.
Pressure gauges with a bottom scale value lower than 0.5 bar, as well as possible separators are not subject to DGRL regulations and cannot be marked CE.
Pressure gauges with a bottom scale value between 0.5 and 200 bars must only comply to good engineering practice rules (Art. 3 – Paragraph 3) and do not have to be marked CE.
No CE symbol is required for pressure gauges without the manufacturer’s name and brand.
In order to protect possible overpressure within allowed limits (“common components with safety functions”), pressure gauges applied to safety devices, have to be considered separately.
Our pressure gauges are manufactured and tested according to European Regulation EN837.
CONFORMITY DECLARATION TO EUROPEAN DIRECTIVES RoHS II, Atex, Lvd-Bt, Emc AS FAR AS RELEVANT.
