It was approved by CNCA and CNAS to be the first laboratory obtaining national accreditation on functional safety capabilities in 2008 with test ability covered by functional safety standards such as GB/T 20438-2006, GB/T 21119-2008, IEC 62061-2010, GB 16899-2011, etc. Besides, monograph “Functional safety technology” was published. Main Business SIL evaluation of safety products and control systems Safety products include Thermocouple /resistor, sensor, transmitter, gas (flame) detector; actuator, valve, positioner; surge protector, safety barrier; logic processor (such as PLC) which applied in the petroleum chemical industry, machinery industry, power plants and other situations; control system includes distributed control system (DCS) for safety related control, the safety related system of elevator and the emergency stop control system (ETS), etc.After passing the safety integrity level assessment and factory inspection, the qualification certification will be issued.Certificate inquiry: www.cnca.gov.cnThe main service includes reviewing design concept, reviewing effectiveness of the techniques and measures for control and avoiding failure, failure mode and effects analysis (FMEA), dangerous failure probability calculation (PFH/PFD), determination of hardware and software safety integrity (both system capability) level (SIL), safety confirmation and the factory audit.Applicable standards: GB/T 20438-2006 (IEC61508:2010)，IEC 62061:2010, GB 16899-2011,etc.SIS evaluation of safety instrument system1、Hazard and Operability Analysis (HAZOP) and Process Hazard Analysis (PHA);2、Protection layer analysis (LOPA), SIS system SIL classification;3、SIL verification and SIF loop;4、SIS system safety manual and safety parameter review, SIS field inspection, etc.
Training The training courses on functional safety are designed for relevant research institutes, manufacturing enterprises, design Institute and users of safety related system/safety instrumented systems to help relevant personnel to get the knowledge and skills of functional safety used in design and implementation of safety related products, control systems and safety instrumented system. The courses also include analysis of the potential problems and solutions of safety related products or systems in every stage of their life cycle relying on extensive practical experience and communication on management concept, technical route and industry trends. A certificate authorized by Ministry of Human Resources and Social Security of PRC will be issued after passing the training exam.
Training standards: IEC61508:2010(GB/T20438-2017)，IEC61511:2016 (GB/T21119) and other related standard methods.
Type tests of safety products and control system EMC test, climatic and environmental test, mechanical environmental test, electrical safety test, etc. Study and preparation of national, industrial and product standards
Verification and Validation (V&V) of software
The V & V organization is a third-party software which was established with the support of the nuclear and radiation safety center of the Ministry of environmental protection of the people's Republic of China. The V & V organization meet the national regulatory and nuclear power safety requirements. In 2010, the safety assessment center was recognized by the China National Accreditation Service for conformity assessment (CNAS), authorized to carry out the qualification assessment activities for the verification and confirmation of software with different safety levels in accordance with IEC60880, IEC62138 and IEEE1012, equipped with special test software and platform, covering the whole software life cycle, including software quality assurance system review, requirement review, design review, code test, unit test, integration test, system test and confirmation test. V&V can be used in embedded software, control system and industrial software which provide nuclear safety for nuclear equipment. At present, software V&V service has been provided in elevator, ship, rail transit and other fields.
Software Verification & Validation for nuclear level instrument control system
1、IEC 60880 Nuclear power plants-Instrumentation and control systems important to safety-Software aspects for computer-based systems performing category A or B functionsSuch as class 1E UPS system, RPS system, electric protection system, speed control controller of auxiliary feed water steam pump, overcurrent and grounding protection relay and other software;
2、IEC 62138 Nuclear power plants-Instrumentation and control systems important to safety-Software aspects for computer-based systems performing category B or C functions Such as software like monitoring device, control room data processing system.
3、Software Verification & Validation with software integrity level 1-4 in industrial instrument andcontrol system equipment;Such as software like class 1E UPS, charger and inverter control, flow computer, etc.
Safety related software V&V assessment
According to IEC or IEEE standards, the safety related I & CS software shall be subject to the full life cycle software V & V assessment of an independent third party. For example, railway application communication, signal and processing system railway control and protection system software, elevator function safety control software, petroleum, chemical, medical, automobile and other safety related software systems. Services include quality system review, configuration management evaluation, software related document review, static test, dynamic test (unit test, integration test, confirmation test, system test, acceptance test), software common cause failure analysis and evaluation, etc.
Our center provides professional services such as code testing, unit (module) testing, integration testing, system testing, verification testing and validation testing, as well as software design and quality assurance system consulting, especially in industrial embedded software.
