TSG vs. PED/TPED

Opposed to the applicable TSG-regulations, the scopes of the European Pressure Equipment Directives (PED and TPED) are clearly defined. This regularly causes unpleasant surprises for PED and TPED manufacturers during license audits.

European Pressure Equipment Directives are simply not comparable with the Chinese SELO license. Notified bodies just don’t exist in the Chinese world of pressure vessels! And whilst the European directive allow a manufacturer to issue “self-declarations of conformity” for certain types of equipment, self-declarations are not allowed in China. The Chinese authorities only differentiate between pressure equipment requiring a license and license-free pressure equipment. Our experience has shown that the difference is only marginal and that manufacturers also need support (see license mandatory yes/no).

The question as to which is the more conservative: the European directives (PED, TPED) or the TSG-regulations? It can be answered by saying that the applicable TSG-regulations leave manufacturers significantly less freedom in terms of outsourcing, material selection and manufacturing processes. When a manufacturer inadvertently disregards this, he may well encounter considerably more problems.

We strongly recommend that you involve us from the very beginning- ideally during your initial planning phase. This is the most efficient means of kicking off on the right foot and the only guarantee of encountering less problems whilst saving valuable time and money.

SELO License - in short

The demand for pressure devices within the Chinese market is steadily increasing. All manufacturers wishing to enter this ever-growing market need a SELO License.

Boilers

The scope includes stationary pressurized hot water boilers, steam boilers and boilers heated with regenerative fuels.

Pressure Vessels

The scope includes stationary pressure vessels which are divided into different licensing categories depending on pressure, volume and medium.

Safety Equipment

The scope of application includes safety equipment necessary for the safe operation of pressure vessels and boilers.

3rd Party

As of today, third parties are not admitted. This means that only Chinese authorities may perform audits and grant or issue licenses.

Standards

Different TSG-regulations may apply to your pressure vessels, boilers and safety equipment. But what exactly are the TSG-regulations?

History

The safety of pressure equipment has always been considered as a national obligation. Over the years, two standard systems have been established worldwide - Where does the SELO license fit in?

Organisation

What many do not know is that numerous other Chinese authorities are also involved in the licensing process.

TSG vs. ASME

Opposed to the applicable TSG-regulations, the scope of the applicable ASME codes is clearly defined.
