A passport for a ventilation system is a mandatory document drawn up by a specialized organization during commissioning. First of all, the customer himself needs certification of ventilation, since it is here that all the indicators of the system’s operation for the entire time of its operation are recorded. In addition, a passport is needed for presentation to numerous inspections.
There are several types of passports for supply and exhaust ventilation, and the quality of their design and completion depends entirely on the good faith of the commissioning company.
To require a properly executed document, the customer needs to understand why a ventilation installation passport is needed and how it should look.
Certification of ventilation systems
Certification of the ventilation system is carried out only once - during commissioning. However, if the scheme is undergoing significant modernization, it is necessary to draw up a new document.
To obtain a passport according to SNiP, the ventilation system must undergo aerodynamic tests. Sometimes in the range of work on certification even include the development of estimates for modernization or repair.
Certification for natural ventilation systems is not carried out. However, if such a document is required, it is drawn up. Its shape is simpler than a standard example of a passport of a ventilation unit. And in the attached protocols, indicators of the effectiveness of natural ventilation are recorded.
A passport for a ventilation system without a network is not required. However, during operation, it is necessary to enter somewhere notes on repairs, inspections and upgrades, therefore, usually any mechanical ventilation systems, including window fans and thermal curtains are issued. Sometimes, a passport issued by the equipment manufacturer, which is supplemented by test protocols, is used as a simplified sample of a ventilation passport.
During commissioning, specialists can correct minor defects in the system, adjust it and explain to the customer the rules for using ventilation.
Passport is a perpetual document. Re-sample of the passport of the ventilation system is issued in case of loss, with significant modernization, change of route. The results of aerodynamic tests are applied to the passport in the form of a protocol. As a rule, the last protocol is valid for 12 months. At the end of this period, it is necessary to conduct new tests, to investigate the state of the system.
Who carries out certification of ventilation
Since certification does not apply to construction processes, any authorized laboratory can conduct it. The conditions for the certification of supply and exhaust ventilation are specified in a written agreement. An individual entrepreneur can also issue a sample passport for ventilation, which is much cheaper, since it excludes payment for intermediary services.
If the staff of the installation company has designers and equipment adjusters, they can also issue a passport for the installed ventilation system. As a rule, large installation companies keep their own commissioning specialists.
Testing laboratories can issue a passport for a ventilation system according to SNiP. As a rule, they provide services of a sufficiently high level.The lack of cooperation with them is the lack of specialists in the field of ventilation, who could analyze the obtained indicators and help solve problems.
And the last option is specialized organizations. It is the ventilation engineers who are well versed in their work. But the quality of the measurements may be lame due to poor equipment.
Passport for ventilation system
Adjustment of ventilation systems is carried out in two stages.
This means that at the first stage, individual tests and adjustment of equipment will be carried out. Based on the results of which the commission as part of sanitary and epidemiological surveillance and fire supervision issues a permit for the operation of the building - a passport for the ventilation system. Samples of passports of ventilation systems are subject to the requirements of SNiP 3.05.01-85. Passports are filled out by the contractor and are given to the customer together with the commissioning certificate and axonometric schemes. Two copies of the passport are filled, one remains in the commissioning organization, the other is handed to the customer. If the second instance is lost, it is easy to duplicate it. In addition, the second copy of the passport provides an opportunity for specialists-adjusters to answer some questions regarding the operation of ventilation, without even leaving their office. Some general contractors ask for 2 or 4 copies, about which the corresponding note is made in the contract.
Although axonometric schemes are not included in the mandatory package of documents, the organization-adjuster usually issues them.
The received passport of the ventilation system at this stage is the most important document presented to the sanitary and epidemiological surveillance.
Passport for ventilation unit
Ventilation systems must be checked once every 5 years, as well as when changing the owner or if the primary documentation is lost. This is one of the rules for the operation of power plants.
Commissioning in this case is carried out in installations requiring verification. The work is called the adjustment and testing of ventilation systems for technological or sanitary requirements.
More extensive work is required than in the initial tests to obtain a passport for the ventilation system.
All test data are entered in the technical report (in contrast to the technical documentation in the first case). The technical report details the facility information, test schedule. The document contains the following data:
- air exchange in the form of a table;
- air condition in the building;
- noise level and other indicators of ventilation performance.
One sample passport ventilation unit sent to the operational service.
Passport of ventilation according to SNiP
The passport form of the ventilation system according to SNiP is usually used when putting in new buildings. Certification of ventilation is subsequently carried out regularly, therefore, there are several tables in the document that are gradually filled in during each inspection. All information about repairs and modernization of equipment is entered here. The sample passport of the ventilation system is a multi-page document fastened with a spring or stitched into a binding.
The sample passport of the ventilation unit includes about 8 main pages (without sections on repair and replacement of components). The ventilation system passport is supplemented by a sample protocol and, in some cases, a shortened operating manual for the ventilation unit.
If necessary, the following protocols are applied:
- aerodynamic fan testing;
- network tightness;
- noise and vibration level;
- level of overpressure and some others.
Often, the measurement results are stored in electronic form in the commissioning organization, and in the passport of the ventilation system, according to the established model, a note is made about the availability of protocols and their issuance upon request.
Cost of certification of ventilation
The price of the passport for exhaust ventilation is calculated in the estimate agreed with the customer. Re-certification within the framework of production control is done at a discount. If re-certification is carried out by another organization, the sample passport of the ventilation system is changed and no discount is provided.
The cost of the passport of supply and exhaust ventilation depends on the size of the object, the branching network and the amount of equipment.
As a rule, travel and transportation expenses are calculated separately and added to the estimate.
If the scope of work for issuing a passport for exhaust ventilation is large, a phased payment is possible.
Keeping a ventilation passport
-
- Passport notes
-
- Test reports
The passport for exhaust or supply ventilation is kept by the person responsible for the operation of the equipment: mechanic, power engineer or contractor, if the enterprise is not industrial.
In the sample passport of the ventilation unit, it is necessary to make timely notes on the repair, any changes in the circuit and apply the protocols of all the tests performed.
Over time, many test reports accumulate, so only the very first and last 5 are left.
