When welding pressurized equipment and pipes, relevant regulations (standards) require testing in accordance with the weld and hook method of pressure parts, weld method of non-pressure parts (ex. lags) with pressure parts, type of parent material, type of weld rod, preheat temperature, stress relieving method, type of shield gas, etc., and welding using a previously validated method.
Welding engineers, welding methods, and welding method inspection reports certified according to the relevant regulations are required when welding flanges with the wells of our flanged thermowells as well.
We believe that assuring the weld quality required by the relevant regulations (standards) is necessary in preventing any trouble occurring with welds and in enabling the stable operation of applicable equipment and plants. We, therefore, strive to maintain and improve the skills of engineers and of weld quality through the acquisition of compliant engineers and welding certifications.

We comply with the CE mark under the ATEX Explosion-Proof Directive. All products sold in any country where European Union (EU) and European standards are applicable must carry this CE mark. CE marking is obligatory for various devices, parts, consumer electronics, pressure equipment, etc., and currently in practice. ATEX stands for the French word, “Atmospheres Explosibles (explosive atmosphere)”, and any electric appliance and disaster prevention system intended for use in explosive atmospheres are subject to that regulation if they are manufactured, sold, distributed, or installed in EU countries. Technical data compliant with the ATEX Directive has been submitted to the Dutch certification organization KEMA for auditing, and therefore we are in compliance with the CE mark. |

| We are in compliance with the Pattern Approval of Measuring Instrument needed in China. Pattern Approval was granted to Yamari by the China State Bureau of Technical Supervision, Measuring Devices Supervision and Management Regulation, Chapter 3: Measuring Devices Import Examination, Article 12: Import Measuring Devices Examination Regulation. Products subject to this certification include thermocouples and resistance temperature detectors.

|
 |
|
| Following the ATEX Explosion-Proof Directive, our multi-point temperature sensors currently also comply with Japanese pressure-resistant explosion-proof standards. Pressure-resistant explosion-proof construction of electric devices means that the vessel can withstand and will not be damaged by internal explosions caused by explosive atmospheres that enter it, and the target explosive gas or vapor outside the vessel cannot ignite through any of the joints or structural openings. Such devices, therefore, can be used in dangerous places where explosions may occur.

We have recently obtained Russian certifications (GOST-R).
As the safety and quality of our products has been approved, we can utilize the certifications listed below if necessary so as to deliver thermocouples and resistance temperature detector to Russia problem-free.
Our affiliate company in Singapore, Yamari Singapore Pte Ltd, has also obtained the same certifications and can do likewise.
|
| Also called “type approval” and needed for clearing Russian customs.
We have obtained a VNIIS Letter that proves that no type approval is necessary for our thermocouples and resistance temperature sensors.
|
| This certification provides a product license that enables use of measuring devices in the Russian Federation. We have obtained pattern approval for sheathed thermocouples, protection tube type thermocouples, sheathed resistance temperature detectors, and protection tube type resistance temperature detectors.
|
| 3.EXPLOSIONPROOF APPROVAL |
 |
|
We have obtained Russian certification for pressure-resistant explosion-proof constructions for our several types of devices such as 2-wire temperature transmitter and multi-point temperature sensors based on sheathed thermocouples and sheathed resistance temperature detectors. |
| 4. PERMISSION FOR APPLICATION |
 |
|
For explosion-proof products that we deliver to Russia, we have obtained licenses for use in explosion-proof areas after having passed a quality audit by the Russian State Inspection for Technical and Mining Supervision (GGTN:GOSGORTEKHNAZOR), an organization which supervises and constructs guidelines concerning industrial safety. |
| Measuring devices are usually calibrated by GOST when installed, but as we have obtained primary calibration certification we are exempt from this initial calibration, which can thus reduce initial costs.
