Since joining the world trade organization, China has become more and more close to the world. China has more and more gas bbq grill exported all over the world. How to produce qualified products, access to CE certification in Europe and CSA or UL certification in North America has become a problem that every enterprise must solve. How to solve these problems, first of all, we must for each product related national standards have to be able to understand, according to the standard requirements, the production line with the standard requirements of the products, smooth their products will be exported to foreign countries.
In these exports to foreign products, the largest number of exports, the most widely used gas bbq, that is familiar to everyone BBQ. The gas bbq is very popular outdoor appliance in foreign countries, but to the European and North American standards but there is a big difference. Due to the differences in standards, the same products can meet the requirements of the North American standards, but may not be able to meet the requirements of European standards. Therefore, it is very important to understand the differences of the corresponding standards. This content will explain these differences. Hope to be able to provide some help to the relevant manufacturers. In addition, the gas bbq grill in China has gradually been recognized by everyone, the relevant standards are also in the formulation, hoping to have reference to the editor.
This paper mainly to the European standard EN498:1998 "dedicated liquefied petroleum gas burner - Outdoor oven" ANSI Z21.58a:2008 "and the North American Standard" as the basis for gas oven outdoors, to explain the different requirements of the standard and standard difference of main burner. Following the EN498:1998 "special liquefied petroleum gas burner - Outdoor oven" EN498, ANSI "Z21.58a:2008" ANSI outdoor gas oven Z21.58a
Types of gas used
EN498: appliance can be designed using liquefied petroleum gas or propane gas. The use of butane gas alone. Not included in this standard. In the test, according to ranju different classification, using different reference gas and gas line.
ANSI Z21.58a: appliance can be designed using natural gas, artificial gas, mixed gas, liquefied petroleum gas or gas. Gas appliance can be connected to the gas cylinder or connected in pipeline gas supply system.
Air tightness test
EN498: under 15Kpa test pressure, leakage is not more than 0.07L/h, measurement error should not be greater than 5ml/h. The test is divided into two steps, the first is to close all the valves, for testing; second is all valve open, will change the nozzle, test. The standard requires that each test should be carried out before the other tests and after all tests are completed, and the experimental values should meet the requirements of the standard.
ANSI Z21.58a: does not involve air tightness requirements.
Heat load test
EN498: single furnace head after burning 15min, using standard gas, measuring its thermal load, and the deviation of the rated value shall not exceed 8%, when the nozzle size is less than or equal to 0.5mm, the required deviation shall not exceed 10%.
