Certificate of pneumatic testing of pipelines
Pneumatic method: diagnosis by pumping the system with high pressure air. Often the method is used for external systems if the temperature on the thermometer is less than +5 Celsius.
The procedure for crimping pipes by pneumatic testing is given in the same SanPiN; the test report is drawn up in the required form, which is given in Appendix No. 3.
Requirements for drawing up test documentation:
- Filling in the name of the city and the date of compilation.
- Indication of the members of the commission (as in the hydraulic test, three parties are involved).
- Description of the pipeline: length, diameter, material of pipes and joints.
- Information about the pressure value: calculated value, to what value the pressure in the pipes was increased, final pressure, amount of reduction. The crimping time is indicated.
- In the “Decision of the Commission” section, each of its members signs with a transcript if the pipeline has passed pneumatic diagnostics and is sealed and durable.
The essence and types of crimping
Nowadays heating is most often carried out by a “water circuit” system. At the same time, heated water circulates through the works, imparting its thermal energy to the premises. Leaks are unacceptable; the pipeline must be completely sealed for normal operation. Pressure testing specifically creates a larger volume in the pipe than normal.
When this is done using air, it is called pneumatic pressing.
When using water, then hydropressing. The latter method is considered safer and therefore more popular. For this reason, an example of hydropressing is provided as a form.
When testing, it is recommended not to exceed the pressure inside the pipe more than 15 MPa. If we are talking about raising pressure with water, then there are limitations. The maximum possible pressure should not exceed the normal operating pressure by more than 30%.
Certificate of testing of external and internal sewerage for spillage
A test report for internal and external sewerage is drawn up as a result of checking the operability of the system. It confirms the position of the commission that the system has withstood the test of a spill of water, and the design complies with the design documentation, GOSTs and standards.
Diagnostics of the normal functionality of the sewer system is necessary when installing a new facility or after carrying out repair work on an existing system. Information about the performance check is entered into the report. The form is drawn up in the form specified in Appendix “D” to the Code of Rules 73.13330.2012.
The act specifies:
- name of the system and the facility in which it is installed;
- information about the members of the commission. Representatives of three organizations are needed: the general contractor, the customer and the installation company;
- information about the name of the project is written down;
- the results are entered: the number of simultaneously connected devices, as well as the connection time or filling of water on the floor (unnecessary ones are crossed out);
- the third paragraph states that no leaks were detected at the joints and through the walls. This means the system is suitable for use.
The decision is signed by the members of the commission.
What is pressure testing of a heating system - test goals. Press!
To put a heat supply or water supply system into operation, after all the necessary installation work has been carried out, it is necessary to test the finished structure.
At this stage, hydraulic tests are carried out, based on the results of which a certificate is drawn up indicating the suitability of the system for its intended use and its ability to withstand hydraulic shocks.
Purpose of testing
Carrying out hydraulic tests is not a whim or a whim.
Tests must be carried out after the creation of a new network or after major repairs, preventive maintenance and reconstruction of an existing one, and also before the start of the heating season.
After which new testing is carried out, and this continues until results that correspond to the norm are obtained. Actually, there are two stages of testing: preliminary and final.
Please note: pressure testing is carried out to check tightness and integrity, as well as to detect possible defects in any section of the water supply system, including boilers.
Such checks are the most popular pressure testing process for heating systems. This happens by simulating water hammer, when pressure is pumped into the system several times higher than the standard one.
Specialist's note: all defects and deficiencies discovered during the pressure testing must be eliminated immediately and without delay.
All rules for conducting inspections of this nature are always strictly regulated.
For hydraulic tests, regulatory documents are used. These are two SNiPs: 41-01-2003 and 3.05.01-85, as well as “Rules for the technical operation of thermal power plants” from 2003.
The test procedure is quite transparent and understandable:
Important test details
Actually, the act of conducting hydraulic tests becomes evidence of the tests performed.
In this case, the checks themselves can be carried out in one of two ways:
- manometric;
- hydrostatic.
The first testing method involves the use of pressure gauges that record and demonstrate the pressure in the system.
Please note: using pressure gauges, the amount of excess pressure is determined, which allows us to draw a conclusion about the reliability of the test.
The second method checks the real readiness of the system for operation by checking its performance at a pressure 50% higher than the standard. Any test lasts at least 10 minutes, the permissible pressure drop during pressure testing is no more than 0.02 MPa.
Good to know: the main document evidencing the conduct of tests is the corresponding act.
Such an act must be drawn up in the form and signed by all responsible persons.
This document is extremely important; it must be filled out and signed on the same day as the inspection. A sample form is given in SNiP 3.05.01-85.
(You can download the heating system testing report form here).
There are also a number of strict requirements for the design and structure of this document:
- the act must indicate the date of the test and the drawing up of the document;
- all responsible persons for carrying out pressure testing must be listed;
- It is mandatory to indicate the full name of the object of inspection and the address where it is located;
- it is necessary to specify the test parameters, the location of the system check;
- bringing pressure indicators during tests: working, test and pressure at the end of tests;
- indicators of pressure drop in the system during the pressure testing process;
- results of inspection of structures and main components;
- a list of repairs carried out, if any;
- the fact of acceptance and a complete conclusion about the readiness of the system for operation;
- signatures of all authorized persons.
Certain points may vary somewhat depending on the nature and complexity of the object on which the tests were carried out and the reasons for their conduct.

Fire test reports
During testing for the performance and safe operation of fire equipment, several reports are drawn up:
- checking fire hydrants;
- diagnostics of internal water supply;
- checking for the safety of use and compliance with labor protection rules of fire escapes.
Fire hydrants
Testing the performance of hydrants for water loss is carried out twice a year and is often combined with checking the fire-fighting water supply system. Based on the results of the inspection, an act is drawn up and signed by the commission. Mandatory members: a representative of the fire inspection and a representative from the organization in which the inspection is taking place. Also, the commission may consist entirely of company employees.
The act states:
- general organizational information (information about the company, date and place of compilation);
- the main part describes the members of the commission and the progress of the test. Information about hydrants is presented in tabular form. The location address, diameter, pressure, water yield and affiliation of the hydrant are indicated;
- in the final part, compliance (or non-compliance) with the requirements of the hydrant condition is established.
At the end, the act is signed by authorized members of the commission.
Internal fire water supply
The act establishes the presence or absence of defects and malfunctions in the fire water supply system. The inspection is carried out by responsible employees of the enterprise. Frequency – at least twice a year; for flammable industries, inspections may be scheduled more often.
Internal fire water supply (IFP) is a complex system of pipes, sensors, and switches. Therefore, it is often checked by a labor protection or fire safety specialist, as well as by persons who are trained in fire safety.
The act is drawn up on letterhead or plain paper indicating the details. Be sure to register:
- information about the organization and participants of the inspection;
- information about the object being checked;
- inspection results;
- recommendations for eliminating defects and malfunctions, if any are found;
- signatures of responsible persons.
Roof fencing test report
Technical requirements and roof testing methods are enshrined in the same GOST as the standard for fire escapes and stepladders (53254-2009).
Tests are carried out at intervals of five years, integrity checks are carried out every year. The results are documented in acts.
The conditionally completed act can be divided into three parts:
- General information. Information about the tested object and the inspecting organization is entered here.
- Information about the inspection (what manipulations were carried out, what tools were used).
- Test results (compliance with GOSTs, integrity and safety of the structure).
The agreement of the commission members during testing is confirmed by their personal signatures.
Organizations with a license from the Ministry of Emergency Situations have the right to conduct inspections and tests. Defects found must be corrected.
Test report for ladders, racks and stepladders
Inspection and testing of racks, ladders and stepladders is carried out at least once every six or twelve months (depending on the object being tested and the material from which it is made).
Tests and checks for safe operation can be carried out by specialized organizations from outside or a commission specially created at the enterprise. At the same time, its members must be trained; an occupational safety or fire safety engineer is usually appointed as the chairman of the commission.
As a result of the diagnosis, the commission draws up a report; it is better to document it with the date of the inspection. The header indicates the name of the document, date and place of compilation. It is also important to indicate the details of the organization, list the members of the commission: their positions and full names.
In the main part, describe the tests of stepladders, ladders and racks:
- how many were checked, their inventory numbers, belonging to the workshop and department;
- what load was used and for how long;
- presence and absence of defects;
- availability of an assigned inventory number.
As a result of the test, suitability (or unsuitability) for use is established: they are safe, can withstand the required load, do not have defects in connections and fastenings, do not have sharp edges or burrs.
The signing of the act by the commission members indicates agreement with the results of the inspection.

Installing the device in a heating system
Pressure gauges are mounted using special three-way fittings. Thanks to them, devices can be changed and serviced without stopping the entire heating system. Moreover, taking into account the different pressure in each area, more than one pressure gauge can be installed inside a house (or apartment) equipped with a heating boiler. The presence of several instruments also simplifies pressure testing of pipelines, which is periodically carried out to monitor the reliability of heating.
The process of installing a pressure gauge is not particularly difficult for most people - the work does not require any special experience or specialized tools. To install the device on a specially designed fitting, a regular plumbing kit is sufficient. However, if you choose the option of inserting a pressure gauge into the supply pipeline, installation will require a welding machine.
To protect the insulation from moisture, waterproofing and vapor barrier are used, which differ in their characteristics.
When using centralized heating, installation of the device is not the responsibility of the users - it is located as part of a waterworks unit, usually located in the basement of the building. The ideal place to place the pressure gauge is directly next to the boiler. It is not advisable to place other fittings between the device and the boiler (see How to install a solid fuel boiler, piping).
