一、海綿泡沫往復壓縮*性變形測定儀主要用途：                                                   
本機主要依據ISO1856方法A（ASTM D3574—D JIS K6400-7）設計，用夾具將海綿壓陷至原始厚度的50%，放置將溫度調70的恒溫箱內，待至22個小時之后從中取出壓縮器，將試樣從壓縮器中取出放置30min后，測量厚度，計算其變形量       
                            
二、海綿泡沫往復壓縮*性變形測定儀參數：                                                   
試樣要求：                  50mmX50mmX25m                               
在測試薄型試樣時，應使用玻璃板，其厚度為 1-1.5 mm，邊長為 50^55 mm,"                                   
恒溫箱控制溫度：       準確到土10℃                                  
恒溫箱工作電壓：       220V    

A, sponge foam reciprocating compression permanent deformation apparatus main use:

This machine is mainly based on ISO1856 method A (ASTM JIS K6400 D3574 - D - 7) design, fixture for sponge sag to 50% of the original thickness, placing temperature adjustable constant temperature box 70, after to 22 hours from compressor, place the sample from the compressor after 30 min, measuring thickness, calculate its deformation

Second, sponge foam reciprocating compression permanent deformation apparatus parameters:

Sample required: 50 mmx50mmx25m

Should be used when testing thin specimen, glass plate, its thickness is 1-1.5 mm, length is 50 ^ 55 mm,"

Constant temperature box temperature control: accurate to soil 10 ℃

Incubator working voltage: 220 v
