Identification of solid wood furniture should look at the pattern
She said that the "General Technical Conditions for Wooden Furniture" expressly stipulates that: solid wood furniture is furniture made of solid wood sawn wood or solid wood board as the substrate, and the surface is treated; or solid wood sheets are used on such substrate The furniture after the board veneer (wood veneer) is veneered and then painted, including three types of solid wood furniture, solid wood furniture and solid wood veneer furniture.
Among them, the description of all solid wood furniture is that all wooden parts (except mirror pallets and beading) are furniture made of solid wood sawn wood or solid wood plate. Solid wood furniture refers to furniture whose base material is made of solid wood sawn wood or solid wood plate and whose surface is not covered. Solid wood veneer furniture refers to furniture whose base material is made of solid wood sawn wood or solid wood plate, and solid wood veneer or veneer (wood veneer) is stuck on the surface. In addition, the regulations also propose relevant standards for wood furniture, wood-based furniture, and comprehensive wood furniture.
"Combined wood and board furniture" is not a kind of "solid wood furniture", but "integrated wood furniture". In the new national standard "General Technical Conditions for Wooden Furniture", according to the main material classification of product composition, wooden furniture can be divided into three types: solid wood furniture, artificial board furniture and comprehensive wooden furniture. Among them, comprehensive wood furniture refers to furniture made of solid wood, artificial board and other materials. At present, many wooden furniture produced on the market are comprehensive wooden furniture. According to the standard interpretation, "base material" is "the material used to make the main parts of furniture, also called the main material. Even if only one of the base materials is made of artificial board, and the other is made of solid wood, it cannot be called solid wood furniture. It can only be called comprehensive wood furniture. "President Zhang Ping emphasized.
President Zhang Ping reminds consumers that when buying solid wood furniture, it must be distinguished that "board-wood combined furniture" is not "solid wood furniture"; one way to judge whether the furniture is solid wood is to look at the wood grain and scars. A cabinet door, the outer surface of which looks like a pattern. That corresponds to the position of this pattern change. If you can see the corresponding pattern in the inner layer of the cabinet door, you can judge it as a solid wood cabinet door. In addition, looking at scar knots is also a good way to identify pure solid wood, optimistic about the location of one side with scar knots, and then look for the corresponding shape of scar knots on the other side; for consumers who buy solid wood furniture, fill out the sales contract It should be clearly marked, and the most important thing is to write special terms in laws and regulations, so as to protect rights when disputes arise.
A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.
Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges':
There are many different flange standards to be found worldwide. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. Common world standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5
