Hardware handshandle has what specifications, need to undertake what to testIssuing time:2022-03-15 16:42 Shake handshandle common specification has the cent of single hole and double hole shake handshandle. The length of hole distance of double-hole handle is generally a multiple of 32. Based on hole distance (hole distance refers to the distance between two screw holes of a handle, not the actual length, the unit is mm), it can be divided into: 32 hole pitch, 64 hole pitch, 76 hole pitch, 96 hole pitch, 128 hole pitch, 160 hole pitch, 192 hole pitch, 224 hole pitch, 256 hole pitch, 288 hole pitch, 320 hole pitch and other common specifications. Hongjingyuan Handle has seven types of tests: Salt spray test, salt spray test is mainly to test the service life of products, and to test the use condition in special environment, salt spray test is divided into: Neutral salt spray test for 48H Acid salt spray test for 24~48H Cass test (Copper accelerated test) Saline immersion test, mainly for organic coating and PVD surface treatment products, to check whether the product surface will change color and delamination during use.
