Field Load Test Based SHM System Safety Standard Determination for Rigid Frame Bridge

The deteriorated continuous rigid frame bridge is strengthened by external prestressing. Static loading tests wereconducted before and after the bridge rehabilitation to verify the effectiveness of the rehabilitation process. Thestiffness of the repaired bridge is improved, and the maximum deflection of the load test is reduced from 37.9 to27.6 mm. A bridge health monitoring system is installed after the bridge is reinforced. To achieve an easy assessmentof the bridge’s safety status by directly using transferred data, a real-time safety warning system is createdbased on a five-level safety standard. The threshold for each safety level will be determined by theoretical calculationsand the outcomes of static loading tests. The highest risk threshold will be set at the ultimate limit statevalue. The remaining levels, namely middle risk, low risk, and very low risk, will be determined usingreduction coefficients of 0.95, 0.9, and 0.8, respectively.

Honey Safety Standards and Its Impacts on China's Honey Export

Food safety standard draws increasing concerns on agricultural trade throughout the world.This paper aims to assess the impact of maximum residual limit standard（MRL） of chloromycetin on honey exporting from China.To achieve this objective,the paper discusses the trends of China＇s honey production and export practices,analyzes changes on MRL of chloromycetin adopted by major importing countries,and use a gravity model to estimate the impact of MRL of chloromycetin on China＇s honey export.The results show that despite the rapid growth of China＇s honey production,honey export has declined significantly since 2000.The major reason of declining honey export was mainly due to the more stringent food safety standards indicated by MRL of chloromycetin imposed by importing countries on their honey imports.

Impact of Food Safety Standards on Food Export

This article research the food quality standards covered global and international regulations on food safety and quality, and public and private standards. The effect of global character of food safety and quality standardization shows that the important effect is increasing marginal costs of certification and accreditation, which puts pressure on export company profits in different countries. Main conclusions yield insights into the key following points： Increased food safety has been associated with higher income. Consumers and governments can afford to focus more on reducing food-borne safety risks once basic quantity needs for foods have been met or are in the process of being met. This suggests that policies focused on increasing income are the surest path to improving food safety in all countries. Food safety regulations should be designed to meet the food safety demands of consumers in rich countries and, at the same time, further the interests of both consumers and producers in poor countries.

Revision of the National Standard on Safety Specification for Power Driven Vehicles Operating on Roads

The national standard--Safety Specifications for Power Driven VehiclesOperating on Roads--is the most basic technical regulation for safety and technical management ofmotor vehicles in China. It is the safety and technical basis for the Public Security TrafficControl Dept. to register new vehicles, periodic inspection of vehicles under operation andinspection of vehicles involved in traffic accidents. It is also one of the important technicalbases of our country for compulsory inspection of new vehicles on fi-nalization of its model,ex-works inspection of new vehicles and the inspection of imported motor vehicles. Since the formalcountrywide implementation of GB7258-1997 Safety Specifications for Power Driven Vehicles Operatingon Roads on Jan. 1, 1998, the standard has played a very active role in strengthening the operatingsafety management of motor vehicles, improving the operating safety level of motor vehicles, and insafeguarding road traffic safety, etc. However, along with the rapid and sustainable growth of ournational economy, the number of motor vehicles has increased rapidly, especially privately-ownedautomobiles, so that the incidence of road traffic accidents rises yearly and the road trafficsafety situation is becoming increasingly serious. Therefore, the General Administration of QualitySupervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) and theStandardization Administration of China (SAC) have issued the revised standard GB725 8-2004 SafetySpecifications for Power Driven Vehicles Operating on Roads, which will be put into effect onOctober 1, 2004. The timely revision of this standard is very necessary for upgrading the safety andtechnical requirements for motor vehicles in China.

Food Safety & Standards

An increasing number of people have realized that food safety is an important issue for public health. It not only concerns public health and safety, but also has direct influence on national economic progress and social development. The development and implementation of food safety standards play a vital role in protecting public health, as well as in standardizing and facilitating the sound development of food production and business. After China became a WTO member, food safety standards, which have been indicated by Application Agreement of Sanitary and Phtosanitory Measurements (SPS Agreement) of WTO as the sanitary measurement for food import and export, have a special and great influence on Chinese food industry and trade. The development and revision of food safety standards have drawn great concerns from all stakeholders including the government, food industries and consumers.

A holistic strategy for quality and safety control of traditional Chinese medicines by the “iVarious” standard system

An effective quality control system is the key to ensuring the quality, safety and efficacy of traditional Chinese medicines(TCMs). However, the current quality standard research lacks top-level design and systematic design,mostly based on specific technologies or evaluation methods. To resolve the challenges and questions of quality control of TCMs, a brand-new quality standard system, named "iVarious", was proposed. The system comprises eight elements in a modular format. Meaning of every element was specifically illustrated via corresponding research instances. Furthermore, frankincense study was taken as an example for demonstrating standards and research process, based on the "i Various" system. This system highlighted a holistic strategy for effectiveness,security, integrity and systematization of quality and safety control standards of TCMs. The establishment of"i Various" integrates multi-disciplinary technologies and progressive methods, basis elements and key points of standard construction. The system provides a novel idea and technological demonstration for regulation establishment of TCMs quality standards.

Similar to conventional automobiles,same safety problems exist in electric vehicles.In the meantime,since its structural and power features are different,electric vehicles have their particular safety problems.Both domestic and international organizations have released some safety standards for electric vehicles which have also been added and complemented along with the development and research of electric vehicles.

The Standard System and Quality and Safety Standards for Banana in China

Banana is an important tropical fruit and China is the world's third largest banana producer. The standardization level of banana industry not only affects the yield and quality of banana,but also plays an important role in promoting the production standardization and industrialization of other tropical crops. Through the analysis of revision,publicity and implementation of banana standard system in China as well as the study on its standard system and quality and safety standards,it is found that there are some problems such as irrational banana standard structure,short period of validity of standard,low level of quality and safety standards,and loose link between standards and production. At the same time,some recommendations are put forward in order to guide the standardized production and trade,research and management of banana and promote sustained,healthy and stable development of the banana industry in China.
