The complex of procedures on stepwise carrying out actions of standardization and certification of liquid ni-
trogen, argon and oxygen gasificator G-200 is considered. In the process of organization of standardization and
certification procedures the set of regulatory documents was developed that allow starting small-scale production
of gasificators in Kazakhstan. Thus the emphasis on the potential incorporation of the requirements of such do-
cuments is placed from the Eurasian Economic Union.

1. Introduction
Recently cryogenic technologies find more and more
extensive use in various directions of industrial activity [1–3].
The employment of these technologies in the construction
industry, food and oil industry, medicine, cosmetology, mi-
neral processing and agricultural products emphasizes their
functional value. At the same time, adoption and employ-
ment of innovative cryogenic technologies makes it relevant
to the solution of one of the most important problems —
the organization of standardization and certification proce-
dures. Now in connection with this the question of comp-
lex development methods on carrying out procedures of
unification on the basis of the existing regulatory docu-
ments raises. Thus the purpose of implementation of pro-
gressive, improved procedures of standardization is short-
term identification of quality attributes, compliance with
the requirements and the consumer's conditions.
Laboratory of cryophysics and cryotechnology at Al-Fa-
rabi Kazakh National University over the last 10–15 years
actively has been engaged in development and manufac-
ture of low-temperature equipment. In particular, the low-
temperature equipment for gasification of the liquefied
gases, such as nitrogen, argon, oxygen (G-200 gasificator)
is made, the design is developed and the prototype of the
mobile low-temperature thermostabilizer is made, the set
of actions for production of the line for low-temperature
processing of agricultural raw materials and food products
(Cryoline-kz) is held. With increasing sales market and
organization of serial production this type of equipment it
is necessary of legislative and regulatory confirmation of
compliance to requirements of technical regulations and to
provisions of the national standards. Existence of norma-
tive documents is an essential prerequisite for increasing
sales volume and expansion of the range of provided ser-
vices. Considering innovation of the introduced cryogenic
technologies in Kazakhstan becomes clear that each of
them demands special approach when developing standard
documentation.
2. Results and discussion
In this article the set of procedures of stepwise carrying
out actions standardization and certification of liquid nitro-
gen, argon and oxygen gasificator G-200 which designed
and manufactured in the laboratory is considered.
Step 1. Development of technical specifications and de-
scription of functional principle of the gasificator G-200
(Fig. 1). The gasificator G-200 refers to cold cryogenic
gasificators and is designed for storage and gasification of
liquid technical gases and distribution of gaseous product
to the consumer. Important feature of the gasificators is
possibility of automatic maintenance of predetermined
pressure and flow rate. The gasificator consists of a cryo-
genic tank, consisting of an internal vessel (reservoir) and
a casing with effective layered and vacuum thermal insula-
tion, a valve rack, atmospheric evaporators for gasification

of the liquefied gas (including for pressurization of the
tank), reinforcing steel, control devices, protective equip-
ment and pipelines.
The functional principle of the gasificator is the coordi-
nated work of its main components — the vessel for
cryoliquid storage and the productional evaporator. As the
temperature of liquid nitrogen boiling (T = 76 K) with an
atmospheric pressure is much lower than room tempera-
ture, process of pressure increase in a vessel is carried out
by heat supply to liquid for what the evaporator is also
used. Regulating a heat flow or amount of incoming liquid
nitrogen in the evaporator it is possible to set the necessary
operating conditions, both for pressure and for flow rate of
liquid or gaseous nitrogen. The Table 1 below shows the
main technical characteristics of the gasificator G-200.
Step 2. The conformity assessment procedure is applied
at conformity assessment of products or services (in the
form of the declaration about the conformity or the issuance
of the conformity certificate) to the requirements estab-
lished by regulations, standards. The conformity assess-
ment procedure is applied at mandatory and voluntary con-
formity assessment. Conformity assessment procedures are
carried out only by certification bodies and the test labora-
tories, accredited on the right of carrying out such works in
the field of conformity assessment. The expenses associated
with work are paid for conformity assessment by the app-
licant, regardless of the results, on the basis of the contract.
Conformity certificates of foreign countries, end-item test
sheet, conformity marks are recognized in accordance with
international treaties. The recognition of foreign documents
in the field of conformity assessment is carried in accord-
ance with the established procedure by authorized body in
the field of technical regulation. The general requirements
to conformity assessment procedures, consider require-
ments of the documents of the International Organization
for Standardization and the International Electrotechnical
Commission [4–9].

The standardization and certification procedures of cryogenic equipment in Kazakhstan
Authorized bodies operating the certification at the Re-
public of Kazakhstan are:
1. The authorized body on standardization, metrology
and certification (Committee on Standardization, Metrolo-
gy and Certification of the Republic of Kazakhstan of En-
ergy, Industry and Trade Ministry of the Republic of Ka-
zakhstan (National Standard) National Center for Expertise
and Certification).
2. Accredited bodies on the certification of products,
processes, services.
3. Accredited testing laboratories (centers).
4. Accredited organizations on providing the consulting
services in the field of accreditation.
5. Experts are certification auditors.
Procedure of certification is a written acknowledgement
by authorized body that the equipment confirm to the re-
quirements, established in normative documents (National
Standard) and consists of the following actions:
1. Submission of an application by the applicant to the
certification body. If there are several certification bodies
of this equipment, the applicant may submit the application
to any of them, or if at the time of the application the certi-
fication body of this equipment is not exist, the application
is forwarded to the National Standard of the Republic of
Kazakhstan.
2. Directing the decision based on the results of applica-
tion consideration to the applicant. This decision is sent to
the applicant at 2-week period.
3. Registration of the contract between the applicant
and certification body for procedure of the equipment cer-
tification. The executed contract is directed to the applicant
at a 2-week period in 2 copies.
4. The selection, identification of samples of the
claimed equipment and their representation to the test la-
boratory (center). Selection is carried out by the certifica-
tion body on a contract basis. The selection can be carried
out by the applicant and by the appointment of a competent
committee consisting of at least 3 people from among rep-
resentatives of the uninterested organizations.
5. In necessary cases, the certification body may desig-
nate the sampling to the accredited testing commission.
6. The test laboratory (center) carries out the agreed
with the certification body deadlines of testing of the claim-
ed equipment samples and sends its results issued in the
form of a protocol to the certification body.
7. The analysis of the obtained results and decision
making on possibility of issue of the conformity certificate.
8. In case of negative test results, at least on one of the
indicators, tests with purpose of certification are terminat-
ed. The issuance of the conformity certificate and its regis-
tration in the State Register of the Republic of Kazakhstan.
At positive results of the performed works provided by the
scheme of the declared equipment, the certification body
makes out the Certificate of Compliance. This certificate
may have an application that contains a list of the equip-
ment on which its action extends. Validity period of the
Certificate is set by the certification body taking into ac-
count the specifics of the equipment.
9. Marking of the certified equipment with a mark of
conformity. Marking of the equipment with the mark of
conformity is carried out by the manufacturer in the ways
providing the clear image, environmental sturdiness, dura-
bility, etc. The way and the place of drawing is defined by
the certification body.
3. Conclusions
In the organization process of standardization and certifi-
cation procedures the following main results were reached:
1. Maintenance instructions of the G-200 gasificator are
developed and approved. The product code under Commod-
ity Nomenclature for Foreign Economic Activities of Cus-
tom Union FEACN CU is appropriated as 7311 00 910 0 —
Vessels for compressed or liquefied gas, from ferrous ma-
terials: — other with the capacity: — less than 1000 liters.
2. The certificate of conformity №KZ.7500525.05.01.
63266 registered in the State Register of the Republic of
Kazakhstan was issued. The company standard 55816-1910
GE-01-2013 on the gasificator of liquid nitrogen, argon
and oxygen (G-200) is developed.
3. The presence of these regulatory documents is the basis
for creation of the technological line with a serial production of
competitive products. Implemented gasificator conforms to re-
quirements of the company standard taking into account re-
quirements of the Technical Regulations “Requirements to
safety of the equipment working under pressure”. Produc-
tion of the gasificator is carried out according to the design
and technological documentation approved in accordance
with the established procedure.
Currently, the scope of these regulatory documents is spread
only on Kazakhstan territory. Due to the signing of the con-
tract on creation of the Customs Union of Belarus, Ka-
zakhstan, Russia becomes actual creation of unified regula-
tory base. One of the mechanisms of creation such base is
formation of technical committees for the participating
countries. At the moment the Laboratory of cryophysics and
cryotechnologies is a member of the International Technical
Committee TC 114 “Cryogenic and oxygen equipment”. Thus,
a perspective task of the next stage is the development of uni-
fied regulatory documents for the countries of the Customs
Union in the area of standardization and certification of cryo-
genic and oxygen equipment.
