The formulation of tire standards in China has accelerated

Column:Industry dynamics Time:2014-10-14

The entry conditions for tire industry issued by the Ministry of industry and information technology will be implemented from October 1, 2014. The access conditions involve automobile tires and construction machinery tires, and encourage the development of energy-saving, environmental friendly and safe green tires.

Industry access conditions are only basic standards. As the world's largest tire manufacturer, China must have higher mandatory tire technical standards.

Recently, the national tire and rim Standardization Technical Committee (hereinafter referred to as the National Wheel Standards Committee) publicly launched the timetable for the formulation of tire related technical standards: from the second half of 2014, the National Wheel Standards Committee will begin to formulate the test draft of tire snow, slippery and noise and accumulate data; By the end of 2015, the draft of tire slippery and noise limit standards will be completed for approval; In 2016, the application for mandatory standards of tire rolling resistance, wet slip and noise limits will begin.

In line with international standards

Since November 1, 2012, the EU green tire Labeling Act (known as the EU green tire labeling act in the Chinese industry) has been officially implemented.

EU green tire labeling law stipulates that car tires, truck tires and bus tires sold in the EU must be labeled; Tire labels indicate key parameters such as fuel efficiency level, rolling noise and wet road grip; The fuel efficiency is divided into seven grades: A, B, C, D, e, F and G, which are marked with green "a" to red "g" from the best to the worst; Tires that fail to meet the minimum limit shall not be sold in the EU market.

The EU green tire labeling law is implemented in three stages: 2012, 2015 and 2018.

All tyres above class C will receive financial incentives from EU countries. After 2016, class F and G tires will be regarded as unqualified and banned from import and sale. Its core task is to promote green tires and ensure that Europe's energy consumption will be reduced by 20% by 2020. This is also the trend and direction of the development of the world tire industry.

The EU green tire labeling law puts forward high requirements for tire manufacturing technology, especially for the production of high-performance rubber.

China has developed into the world's largest tire manufacturer, exporter and consumer. From 2002 to 2012, the average annual growth rate of China's tire production was more than 15%, and the average annual growth rate of exports was more than 40%.

The EU is an important market for China's tire exports. On the basis of investigation and research, relevant experts concluded that on the eve of the implementation of the EU green tire labeling law, nearly 50% of China's tires exported to the EU could not meet the standards stipulated in the EU green tire labeling law. Among them, about 30% of heavy vehicle tires still fail to meet the minimum requirements of rolling resistance in the first stage of the EU, and 70% fail to meet the minimum requirements of rolling resistance in the second stage of the EU; The rolling resistance of car tires is mostly Grade E and F, most of which can meet the minimum requirements of the first stage of the EU, but generally can not meet the minimum requirements of the second stage.

The national standards of rubber tires in China have not covered such indicators as fuel efficiency level (rolling resistance), wet grip performance and external rolling noise. The EU's implementation of the green tire labeling law directly challenges the design of relevant systems in China.

The implementation of the green tire labeling law by the EU once put great pressure on China's tire industry. This market barrier once seriously hindered the export of Chinese tire enterprises.

Yang Hongshi, export Minister of Qingdao senqilin Tire Co., Ltd., said: "the mandatory standards for tire rolling resistance, wet slip and noise limits formulated by the National Wheel Standards Commission are consistent with the EU green tire labeling law."

Xu Lihong, senior engineer of the national tire and rim Standardization Technical Committee, said: "the tire technical standard we are formulating is different from any previous tire standard. It is a new standard. The key guiding ideology for us to formulate a new standard is to be in line with international standards."

In 2016, the "graded" draft for approval was completed

The existing technical standards of automobile tires in China only have the rolling resistance limit standard (GB / t29042-2012).

As early as during the "two sessions" in 2011, deputies to the National People's Congress suggested strengthening the construction of technical regulations and standards for the tire industry. In June of the same year, relevant state departments responded to this proposal: "during the 12th Five Year Plan period, the National Standardization Administration Committee will strengthen the formulation and revision of tire industry standards; CNCA is actively organizing experts to conduct research and strive to formulate the implementation rules of compulsory certification more suitable for the current situation of tire products industry as soon as possible.

When will the grading standards for tire rolling resistance, wet slip and noise be formulated? This is an issue of general concern in the industry.

With this question, the relevant person in charge learned that: the state has established the China automobile tire laboratory test network and identified seven automobile tire rolling resistance test comparison laboratories; The National Wheel Standards Commission will conduct tire rolling resistance test from March 2015 to accumulate data; At the same time, extensive wet slip and noise tests are carried out to accumulate more test data, and some representative tire specifications are selected and sent to developed countries for test and data comparison and analysis; It is expected to complete the draft classification standard by the first half of 2016; In the second half of 2016, the draft for comments, the draft for review and the draft for approval were completed.

Only with standards can there be quality assurance

The EU green tire labeling law covers almost all automobile tires, involving tire safety, environmental protection, energy consumption and other indicators. In essence, it is a new green technical barrier.

Guo Konghui, an academician of the Chinese Academy of engineering, said, "if there are standards, there is a guarantee for quality. China lacks many technical standards. As for the setting of technical barriers, China has not reached this level. In this regard, China has just started and can not talk about it. Only with the accumulation of quantity can there be a qualitative leap and can we talk about standards."

The formulation of this series of tire standards in China puts forward high requirements for test equipment, facilities and other conditions. For example, among the three indicators of rolling resistance, wet road grip and noise specified in the EU green tire labeling law, the detection data of wet road grip and noise can only be obtained in the tire test field. However, China lacks large-scale tire test sites. It is said that Shandong plans to invest 1.147 billion yuan in Guangrao County to build a national tire testing ground.
