Annex No. 1 to Government Decree No. 182 / 1999 Coll.
ESSENTIAL REQUIREMENTS
INTRODUCTORY PROVISIONS
1. The essential requirements apply to pressure equipment only if the pressure equipment presents the relevant hazard in use under conditions which the manufacturer may reasonably predict.
The essential requirements set out in this Annex for pressure equipment shall also apply to assemblies where there is a similar risk.
2. The manufacturer shall analyse the hazards with a view to identifying those which, due to pressure, are considered by his equipment; The pressure equipment shall be designed and manufactured taking into account this analysis.
3. The essential requirements shall be applied in a manner that takes into account the state of the art achieved and the usual practice at the time of design and manufacture of the equipment, as well as technical and economic aspects that correspond to a high level of health and safety protection.
1. GENERAL REQUIREMENTS
1.1. The pressure equipment shall be designed, constructed and tested and, where appropriate, fitted and installed in such a way that, when it is put into service in accordance with the manufacturer's regulation or under reasonably foreseeable conditions, its safety is ensured.
1.2. When selecting the most appropriate solution, the manufacturer shall apply the following principles in the following order:
(a) to the extent reasonably achievable, exclude or reduce hazards;
(b) apply appropriate protective measures against hazards which cannot be excluded;
(c) inform the user, where appropriate, of the remaining hazards and draw their attention to the need for appropriate specific measures to reduce hazards during installation or use.
1.3. If the possibility of incorrect use is known or reasonably foreseeable, the pressure equipment shall be designed in such a way as to prevent, prevent or, if this is not possible, the user from using the pressure equipment in such a way.
2. DRAFT
2.1. General
The pressure equipment shall be correctly designed with regard to all relevant factors in order to ensure the safety of the device throughout its intended service life.
Appropriate safety factors shall be applied to the design of the pressure equipment using complex methods which are known to adequately calculate an adequate level of safety against all types of failure that are considered.
2.2. Design to ensure proper strength
2.2.1 The pressure equipment shall be designed for a load corresponding to its intended use and other reasonably foreseeable operating conditions. The following factors must be taken into account:
(a) internal or external pressure;
(b) ambient temperature and working temperature;
(c) static pressure and content mass under operating and test conditions;
(d) loading by transport, wind, earthquakes;
(e) reaction forces and moments derived from aid, fixing, piping, etc.,
(f) corrosion and erosion, fatigue, etc.,
(g) breakdown of unstable fluids.
It is necessary to take into account the various loads which may be combined, taking into account the likelihood of their present occurrence.
2.2.2. The design ensuring appropriate strength shall be based on:
(a) on the calculation method referred to in point 2.2.3, supplemented if necessary by the experimental method referred to in point 2.2.4; or
(b) on the experimental design method without calculation of strength according to paragraph 2.2.4 if the product of the highest working pressure PS and V volume is less than 6 000 bar. L or if the product is PS. DN less than 3,000 bar.
2.2.3. Calculation method
2.2.3.1 Resistance to internal pressure and other load aspects
Tolerance for pressure equipment shall be limited to the types of failure which can reasonably be predicted in the operational conditions. It is therefore necessary to apply safety factors that allow for the complete elimination of any uncertainty arising from production, actual operating conditions, stress, calculation models, as well as the characteristics and behaviour of the material.
These calculation methods shall provide a sufficient level of safety, as appropriate, in accordance with the requirements set out in point 7.
The above requirements may be met by using one of the following methods, as appropriate or as an addition to or in combination with another method:
(a) a proposal based on formulas;
(b) a proposal based on analysis,
(c) design based on refractive mechanics.
2.2.3.2. Strength
Appropriate strength calculations shall be used to ensure the strength of the pressure equipment concerned.
(a) The calculation pressure shall not be less than the highest working pressure and shall take into account the effect of hydrostatic and dynamic fluid pressure and the decomposition of unstable fluids. If the container is divided into individual pressure spaces, the bulkheads shall be designed between them taking into account the maximum possible pressure in a particular pressure area relative to the lowest possible pressure in the adjacent pressure area,
(b) the calculation temperature must be taken with an appropriate level of safety;
