In the steel veins of global rail transit, each cable is a “lifeline” that carries safety and speed. What is the key code that determines whether this lifeline can enter the international track? The answer is – “three certificates protect the body”. As the only company in the cable industry in South China that holds ISO/TS 22163 (International Railway Industry Quality Management System) certification, TST cable uses CRCC (China Railway Product Certification) as a shield and EN 45545-2 (the highest fire protection standard in the European Union) as a spear to decipher the ultimate code to the global rail transit market. Today, let us unveil the strategic significance and technical moat behind these three “gold certificates”.
Three certificates in one: the “golden pass” combination of rail transit cables
01 ISO/TS 22163, the “top of the pyramid certification” of the global rail transit supply chain
Gold content: ★★★★★
Developed by the European Railway Industry Union (UNIFE), it replaces the IRIS standard and is the highest level of quality management certification in the global rail transit industry.
Strictness: Covering 32 core processes and 120+ clauses, covering every link from design and development, supply chain management to full life cycle cost control, the certification pass rate is less than 15%.
South China uniqueness: TST cable is the only certified enterprise in the cable industry in South China, marking that the quality management system has reached the international top level.
Customer value:
It is not only a mandatory threshold for bidding for projects in Europe, Southeast Asia and the Middle East, but also a synonym for zero-defect delivery capabilities in the eyes of customers.
02 CRCC, the “key to the country” of the Chinese railway market
Gold content: ★★★★★
A mandatory certification for procurement by China National Railway Group (National Railway) and CRRC Group. Products that have not obtained CRCC certification are not allowed to be put on the train! Double test: pass the full type test of the national accredited laboratory (including more than 300 tests such as combustion, toxicity, electrical, mechanical, etc.) + annual factory flight audit. Customer value: From Fuxing high-speed rail to urban subway, CRCC is the only legal pass to open the trillion-level rail transit market in China, which directly determines the ownership of orders.
03 “Fireproof King Certification” EN 45545-2 that conquered the European market
Gold content: ★★★★★
EU unified mandatory standard, the highest technical benchmark for fire protection of rail transit materials in the world. Life and death test: According to the vehicle fire risk level (HL1-HL3), it is required to pass a full set of tests such as extreme combustion, low smoke and non-toxicity, and low heat release (such as ISO 5660 heat release, EN 50305 smoke toxicity). Customer value: Meet EN 45545-2 = get a safe ticket to the European subway/high-speed rail project, and it is also the core weapon to crush competitors with technology. Deciphering the technical moat behind the “certification password”
It is not easy to obtain these three certificates. Behind them are the five core technical barriers built by TST cable:
01 Extreme fire protection technology
Material formula: Exclusively developed halogen-free flame-retardant polyolefin system, passed the highest HL3 level of EN 45545-2.
Structural design: Multi-layer composite shielding + ceramic silicone rubber fireproof layer, meeting the global multi-standard fire protection requirements such as DIN 5510 and ECE R118.
02 Full life cycle reliability
30-year life verification: Passed the accelerated aging test (humid heat, ozone, UV, hot and cold cycles) required by ISO/TS 22163 to ensure the same life as the vehicle.
Dynamic durability guarantee: The cable withstands 20 million bending vibrations (simulating 30 years of train operation), far exceeding the TB/T 3139 standard. 03 “Zero tolerance” control of hazardous substances
Dual standards: meet the national railway TB/T 3139-2021 (formaldehyde/VOC/heavy metal limits) and CRRC Q/CRRC J26-2018 (extended REACH 224 items + polycyclic aromatic hydrocarbons control) simultaneously.
04 Intelligent manufacturing and zero-defect quality control Strict quality control: Based on the KPI system of ISO/TS 22163, 100% online monitoring of key parameters in the production process is achieved.
Combustion laboratory: Own EN 45545-2 testing capabilities, 48 hours rapid verification of fire protection performance.
05 Global compliance capabilities
One cable to the world: a single product is simultaneously embedded with CRCC, EN 45545-2, ECE R118, DIN 5510 and other standard parameters to avoid repeated certification costs for customers.
Why is the “three-certificate enterprise” the best choice for customers?
1 Bidding for European subway projects
Pain point: The owner requires ISO/TS 22163 certificate + EN 45545-2 HL2 test report.
Our solution: Directly present double certificates + own laboratory report to shorten the customer’s bidding cycle by 60%.
2 China Railway Group EMU procurement
Pain point: CRCC certification is a hard threshold and must meet the latest TB/T 3139-2021 hazardous substance requirements.
Our solution: CRCC certificate + hazardous substance compliance statement to help customers pass the review once.
3 Exporting “Belt and Road” locomotives
Pain point: The project must comply with China’s CRCC, EU EN 45545, and ASEAN fire protection standards at the same time.
Our solution: “Three certificates” as the foundation + multi-national standard pre-certification to reduce compliance risks for customers.
With the “three certificates” as the anchor, sailing towards the global rail transit blue ocean
“Three certificates” is not only a medal of TST cable’s technical strength, but also a strategic cornerstone of TST cable’s global layout. Through the three-dimensional certification combination of system capabilities, local compliance and international performance, TST cable has not only built a strong moat in the domestic market, but also opened the door to the international high-end market. In the future, as the global rail transit network accelerates interconnection, TST cable, holding the “golden pass”, will surely sail to a broader blue ocean with technology as its sail.
