SATURDAY, SEPTEMBER, 17 Gas does everything A gas range, for example, has to pass some 300 tests covering safety, durability and performance before it can wear the association's ap- proval seal, It may have to be sent back to the manufac- turer a number of times with recommendations for its im- provement, before the range is granted the approval for a five year period, Each range, or other appliance, must pass a rigid test every five years, before a manufacturer is given a renewal of the ap- proval seal, Thus each time a manu- facturer comes out with a new model, that model of hot water heater or other ap- pliance must go through the laboratories, And to make sure the same high standard of manufacturing is maintain- ed during the five-year period of the approval seal's life, surprise checks are made by the association in factories, retail stores, warehouses, and even in customers homes, The approval standards are applied not only to ranges, but also to clothes dryers, water heaters, incinerators, refrigerators, furnaces, room heaters, conversion burners, and to equipment used in hos- pitals and restaurants, to deep fat fryers, portable bake ovens, and to accessories such as valves, regulators and ther- mostats, There are 38 classi- fications of appliances which are tested by the association's laboratories. Thousands of models of gas equipment are tested each year, The model must be neat, sturdy and smooth-edged. It must be easy to install, re- pair, clean and adjust with no special tools.

It is to- day impossible to put a range together wrong after taking it apart for cleaning, After inspecting the new model range, the laboratory test engineers load it down with weights and give it other tests for sturdiness.
