China Quality Supervision Letter [2018] No.33
Bureau of Quality and Technical Supervision of all provinces, autonomous regions, municipalities directly under the Central Government and Xinjiang Production and Construction Corps (market supervision and management department):
According to the provisions of the Product Quality Law of People’s Republic of China (PRC) and the Measures for the Administration of Product Quality Supervision and Spot Check, in 2017, the General Administration of Quality Supervision, Inspection and Quarantine organized a special spot check on the national supervision of fireworks and firecrackers (hereinafter referred to as the special spot check). The relevant information is hereby notified as follows:
I. Basic information
This time, 281 batches of products produced by 281 enterprises in 6 provinces (municipalities directly under the central government and autonomous regions) were randomly selected, and 20 items such as component firmness, fuse, fuse firmness, ignition time, main body stability, drug type (chlorate qualitative), dosage, packaging and marking were tested. After inspection, 205 batches of products from 205 enterprises were qualified, and the pass rate of product spot check was 73.0%. 76 batches of products produced by 76 enterprises were unqualified, and the detection rate of unqualified products was 27.0%.
Second, the main features
(1) Intensify spot checks.This time, 450 fireworks and firecrackers enterprises were randomly selected, accounting for nearly a quarter of the total number of production enterprises in the country. Due to the shrinking market demand and the requirements of local air pollution prevention and control on the management of fireworks and firecrackers, 169 enterprises failed to draw samples due to reasons such as changing production, stopping production and quitting, and actually 281 batches of products from 281 enterprises were drawn.
(2) Intensify tracking and spot checks.This spot check tracked 138 production enterprises that failed the special spot check of fireworks and firecrackers in 2016, and 74 samples were actually spot-checked. After inspection, the products produced by 49 enterprises were qualified, and the products produced by 25 enterprises were unqualified for two consecutive years.
(3) Highlight spot checks on concentrated production areas.Combined with the regional distribution characteristics of fireworks and firecrackers, this time, the products in Hunan and Jiangxi industrial concentration areas were selected. Among them, Hunan Province randomly selected 177 batches of products from 177 production enterprises, accounting for 63.0% of the total batch of products, and the pass rate of random inspection was 72.9%; Jiangxi province randomly selected 78 batches of products from 78 production enterprises, accounting for 27.8% of the total batch of products, and the pass rate of random inspection was 73.1%. The pass rate of spot checks in concentrated production areas is basically the same as the average pass rate of this spot check of 73.0%.
(four) continue to implement the traceability and confirmation of the sampling process.The whole process of enterprise sampling, sample sealing, on-site inspection and on-site confirmation of inspection results was recorded by synchronous video, and the key links were captured, which realized the traceability and reproducibility of the sampling process and ensured the standardization and fairness of the spot check. At the same time, the production enterprises participated in the sampling witness work all the time, and confirmed the inspection results on the spot, which improved the fairness and efficiency of the sampling work.
Third, analysis of spot check results
(A) the pass rate of spot checks has improved significantly, but the overall quality level is not high.
The pass rate of this special spot check product was 73.0%, an increase of 20.7 percentage points over 2016, of which the pass rate of spot check in Hunan Province was 72.9%, an increase of 10.4 percentage points over 2016; The pass rate of spot checks in Jiangxi Province was 73.1%, an increase of 40.7 percentage points over 2016. The new standard GB 19593-2015, Fireworks and Firecrackers Combination Fireworks, which was implemented on April 1, 2016, imposes stricter requirements on safety items such as ignition time, products and packaging, structure and materials. Over the past year or so, local quality and technical supervision departments have strengthened enterprises’ understanding and enforcement of standards through measures such as publicizing standards and providing technical assistance, which has significantly improved the overall qualified rate of spot checks on products, but the detection rate of unqualified products is still 27.0%, and the overall quality level is still not high.
(B) Some safety indicators have many problems.
In this special spot check, 20 items related to safety and quality, such as parts firmness, fuse, fuse firmness, ignition time, main body stability, drug type (chlorate qualitative), dosage, packaging, marking, appearance, discharge performance, firing rate and counting error, were tested.
After inspection, the main quality problems of unqualified products include 13 unqualified items, such as marks (transport and sales packaging marks), packaging (transport packaging), fuse, fuse firmness, ignition time, structure and material, fixing agent fragments, main body stability, dosage, discharge defects, discharge height of linear incense products, firing rate and counting error. Among them, the safety problems of ignition time, fuse, fuse firmness, structure and material are outstanding.
First, the ignition time project does not meet the standard requirements.Too short or too long ignition time will increase the safety hazard of the discharger in the discharge process. In this spot check, 29 batches of products failed the project. Among them, 18 batches of firecracker products failed the project, which was less than the minimum ignition time of 3 seconds stipulated in the standard. The main reason was that the enterprise did not install green safety leads or adopted too short green safety leads to reduce the installation time and material cost. Eleven batches of combined fireworks products were unqualified, of which 9 batches were longer than the specified longest ignition time of 8 seconds, and 2 batches were shorter than the specified shortest ignition time of 5 seconds. The unqualified enterprises did not strictly control the length process of the lead.
Second, the fuse project does not meet the standard requirements.Qualified fuse can ensure that the discharger runs out of the dangerous area before the fireworks and firecrackers detonate. In this spot check, 27 batches of fuse wires were unqualified, including 23 batches of firecrackers, 3 batches of combined fireworks and 1 batch of spray products, mainly because green safety leads were not installed.
Third, the fuse firmness project does not meet the standard requirements.If the fuse is not installed firmly, it is easy to cause the fuse to fall off, which will cause consumers to ignite the fast fuse of fireworks and firecrackers by mistake and cause accidents. In this spot check, 24 batches of fuse wires were unqualified, including 23 batches of firecrackers and 1 batch of spray products. The main problem was that no corresponding firm bonding or other fixing measures were taken between the green safety lead and the main body.
Fourth, the structure and material items do not meet the standard requirements.The structure and material of the product is an important technical index to ensure the safety of discharge. If the control is not strict, it is easy to cause dangers such as "scattering", "overturning" and "exploding". There are 18 batches of unqualified items in this spot check. The main problem is that in order to pursue the appearance of the product, a pad is added between the transportation packaging and the sales packaging, and a partition is added between the cylinders; Secondly, in order to reduce the production cost and reduce the paper used for the combined fireworks barrel, the wall thickness of the barrel can not meet the requirements.
(3) There are shortcomings in the quality of small and micro enterprises.
The number of small, medium and micro enterprises in this spot check accounted for 30.6%, 64.8% and 4.6% of the total number of enterprises in this spot check, and the qualified rate of product spot check was 88.4%, 69.2% and 23.1% respectively. The qualified rate of small and micro enterprises is lower than the average qualified rate, which shows that there is still a big gap between the product quality level of small and micro enterprises.
Fourth, the job requirements
In view of the problems found in this special spot check, the quality and technical supervision departments (market supervision and management departments) of all provinces (autonomous regions and municipalities) should conscientiously do a good job in the post-processing work in accordance with the provisions of the People’s Republic of China (PRC) Product Quality Law, the Measures for the Administration of Product Quality Supervision and Spot Check, and the Provisions on the Post-processing Work of National Product Quality Supervision and Spot Check for Unqualified Product Manufacturers.
(a) for the unqualified products in this spot check, the post-processing work should be carried out according to law. If the quality of products found in spot checks does not meet the mandatory national standards, enterprises shall be ordered to stop producing and selling unqualified products according to law and hand them over to relevant departments for destruction or necessary technical treatment in accordance with relevant regulations. The enterprises that randomly check unqualified products twice in a row should be dealt with seriously according to law, and the relevant provincial bureaus should implement the follow-up rectification work for these enterprises one by one to improve the effectiveness of post-treatment of supervision and random inspection.
(2) In view of the safety items in this spot check, especially those with outstanding quality problems, such as ignition time, fuse, fuse firmness, structure and material, the relevant provincial bureaus, especially those in Hunan and Jiangxi, should strengthen local supervision and inspection, urge production enterprises to improve their production technology, strengthen product quality control and ensure product quality and safety.
(3) In view of the unqualified situation in the concentrated production areas in this spot check, the Hunan and Jiangxi provincial bureaus should intensify the follow-up supervision and inspection, and at the same time, continue to carry out quality rectification and quality improvement activities for the concentrated production areas to promote the continuous improvement of the product quality level in the concentrated production areas.
(4) In view of the low pass rate of spot checks of small and micro enterprises, the relevant provinces should organize and carry out quality assistance actions for small and micro enterprises, and promote the improvement of enterprise product quality through such assistance measures as standard publicity, technical assistance and public testing services.
