1.1 This test method covers the determination of the percentage of material in Naval Stores products as defined in Terminology D804 including rosin, tall oil and related products, other than insoluble dirt or similar visible foreign matter that does not yield a water-soluble soap when the sample is saponified with potassium hydroxide. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 1: It has been reported that this method may not be applicable to gum rosin, especially any gum rosin containing volatile terpenes. Volatile terpenes are by definition unsaponifiable matter, and can be lost under the drying conditions described in 8.4. The method is applicable to tall oil rosin and wood rosin as these rosins do not contain volatile terpenes." >
Gardner(加德納),1-18. 1997.6,ASTM D01.34,松脂制品委員會(Naval Stores)證實了和直觀Gardner色度標尺相關聯的儀器法,這個方法基于10mm光程的透明溶液測試,在ASTM D6166中被描述,方法的名稱是“松脂制品及相關產品的標準顏色測試方法-Gardner色度的儀器方法”,類似的產品包括C5、C9樹脂等等。...
中心建成后,將集產品質量檢驗、產品標準研發和修訂為一體,成為國內一流、國際先進的松脂林化產品檢測實驗室,為中國松脂及深加工林化產品突破歐美發達國家技術貿易壁壘,產品銷往世界市場提供強有力的技術支撐,促進中國松脂林化產品產業健康發展。 梧州是中國松脂林化工業的搖籃,松脂生產歷史悠久,名譽海外,歷史上曾有“世界松香看中國,中國松香看廣西,廣西松香看梧州”之說。...
