DIN EN 14595:2016-10EN 14595:2016 (E) 5 Introduction The breather device as specified includes a safety device to prevent the

    31、 contents from spilling out if the tank overturns. The breather may be a separate device, or an integral part of another device. Where the breather device is separate from the safety device (to prevent the contents from spilling out of the tank), the functional performance of these elements in combi

    32、nation is required in order to comply with this standard. Where a flame arrestor is required, EN 16522, Flame arrestors for breather devices, specifies requirements. DIN EN 14595:2016-10EN 14595:2016 (E) 6 1 Scope This European Standard covers the breather device used to ensure normal tank compartme

    33、nt breathing. It specifies the performance requirements and the critical dimensions of the breather device. It also specifies the tests necessary to verify compliance of the equipment with this document. The service equipment specified by this document is suitable for use with liquid petroleum produ

    39、 Breather devices shall be of the re-sealing type and may or may not breathe or vent directly to atmosphere. They shall be designed to prevent unauthorized adjustment of the relieving pressure settings. The functions described in Clause 4 may be provided by one combined device or by separate indepen

    40、dent devices. Discrete devices that are not mounted externally shall have a secondary positive means for being secured. DIN EN 14595:2016-10EN 14595:2016 (E) 7 5.2 Ingress protection The breather device shall be designed, or provision made, to meet the requirements of IP31 in accordance with EN 6052

    41、9. 5.3 Pressure ratings 5.3.1 Above atmospheric relieving pressure (pressure relief) Breather devices shall have a relieving pressure of not more than 12 kPa(gauge) in their normally installed attitude. 5.3.2 Below atmospheric relieving pressure (vacuum) The relieving pressure of breather devices sh

    42、all be between 0,4 kPa (gauge) and 2,5 kPa (gauge) in their normally installed attitude. 5.3.3 Tank overturn The breather device shall be designed to prevent the spilling out of the contents of the tank in the event of an overturn. 5.4 Flow capacity The flow capacity shall be the flow rate (in m3/h)

    43、 of air (at 20 C) achieved by the breather device at the following pressures: pressure flow capacity: 30 kPa above pressure relieving pressure; vacuum flow capacity: 3 kPa below vacuum relieving pressure. 5.5 Temperature range Unless otherwise specified, the design temperature range shall be 20 C to

    44、 +50 C. Where the breather device is subjected to more severe conditions, the design temperature range shall be extended to 40 C or +70 C as applicable. 5.6 Materials of construction The manufacturer shall provide, with the equipment, a full material specification for those parts that may come into

    45、contact with the substances described in Clause 1. 5.7 Dimensional characteristics When the breather device is provided with threaded connections, the threads shall conform to EN ISO 228-1. 5.8 Electrical resistance The electrical resistance between any conductive part of the device which may come i

    46、nto contact with the dangerous goods and its mounting shall not exceed 1 M. 6 Tests 6.1 General Two classes of tests are required: production tests and type tests. Testing methods and procedures shall conform to EN 12266-1 except as specified within this document. DIN EN 14595:2016-10EN 14595:2016 (

    47、E) 8 Unless otherwise specified, test fluids shall be air or other suitable gas. The choice of the fluid is the responsibility of the manufacturer. Tests shall be performed on the complete breather device. 6.2 Production tests 6.2.1 General The number, frequency and sampling methods of production te

    48、st samples shall be not less than those specified within ISO 2859-1 (AQL of 2,5). Production tests shall comprise the following: seat tightness test (EN 12266-1:2012, A.4); and overturn seat tightness test (EN 12266-1:2012, A.4). 6.2.2 Seat tightness test 6.2.2.1 Test procedure With the device under

    49、 test positioned in its normally installed attitude, and closed in a leak -tight condition, a steadily increasing differential test pressure from 0 kPa to the relieving pressure shall be applied. At the devices specified relieving pressure, the differential test pressure shall be held for a time period in accordance with EN 12266-1:2012, Table A.4. During
