一、巖棉制品檢驗標準
公司采用的巖棉類保溫材料多為巖棉板、巖棉管，巖棉管規格由25～377（內徑）×1000×設計厚度，巖棉板1000×630×50、1000×630×100。
巖棉成品的容重為50～200千克/米^3
1、巖棉管
⑴、目測：巖棉管色澤均勻，無燒焦、結疤現象，管身無破損，管壁厚無肉眼可見的偏差。
⑵、強度檢測：57以下的管殼，手持一端平舉，管子應平直、無折斷；57～325的管殼，平舉1.5米處，自由落下，管殼應無明顯的變形，更不應破裂；325及以上的管殼到廠后，管殼應無明顯的變形、破裂現象。
⑶、工具檢測：用直尺檢測管殼的內徑、壁厚、長度。其中長度的允許偏差-3～+5mm；管厚50以下的允許偏差不大于-2～+4mm，50及以上的允許偏差-3～+5mm；內徑100以下的允許偏差-1～+3mm，內徑100以上的允許偏差-1～+4mm。
