常温(20±5)℃,置于阴凉处
The certified value(s) and uncertainty(ies) are determined in accordance with ISO 17034 with an 95% confidence level(k=2). Uncertainty is based on the Total Combined Uncertainty, including uncertainties of characterisation, homogeneity and stability testing. Stability values are based on real evidence opposed to simulation.
The balances used for gravimetric measurements are calibrated with weights traceable to the national standards. The calibration of the balances is verified annually by an external accredited calibration service. This analysis method has been verified using an approach consistent with ISO 17034:2016 & ISO 17025:2017.

This RM is intended for use in a laboratory as a calibration and quality control standard or in method development for analytical techniques.
This reference material meets the specification stated in this certificate until the expiry date, provided it is stored unopened at the recommended temperature here in. If storage after opening is necessary, the RM should be tightly closed and kept from light and moisture.
Read Material Safety Data Sheet (MSDS) and understand any potential hazard(s) prior to the use of this product. All chemicals should be considered potentially hazardous in nature and should only be handled by qualified personnel using established good laboratory practices.
Random replicate samples of the final packaged RM have been analysed to prove homogeneity compliant with ISO 17034.
It is recommended to use 1 mg as the minimum sample size and if less material is used, to increase the certified uncertainty by a factor of two for half sample and four for a quarter of sample.Visit the support section of our website technology videos and frequently asked questions.

2.对环境的影响: 一、健康危害 侵入途径：吸入、食入、经皮吸收。 健康危害：主要影响中枢神经系统，并有眼及上呼吸道刺激症状。急性中毒：短时间接触低浓度，眼及咽喉部烧灼感；浓度增高，有眩晕、恶心、呕吐甚至酩酊状；吸入高浓度还可致死。可致角膜损伤及皮肤灼伤。 慢性影响：长期接触，除粘膜刺激症状外，常伴有神经衰弱综合征。 二、毒理学资料及环境行为 毒性：对动物和人有致瘤作用。以吸入最为危险。 急性毒性：LD50200mg/kg(大鼠经口)；LC5025210mg/m3，4小时(大鼠吸入)；人吸入<5ppm，肝功能略有影响。亚急性和慢性毒性：动物接触0.397g/m3和0.199g/m3，8小时/天，5天/周，数月后出现肝肾损害。接触低于0.099g/m3，出现轻度肝肾病变。致突变性：微生物致突变：鼠伤寒沙门氏菌5pph。DNA损伤：大鼠吸入10ppm。致癌性：IARC致癌性评论：动物阳性，人类无可靠数据。大鼠吸入55ppm×6小时/日×12月，肝血管肉瘤。 致畸性：大鼠吸入200ppm(妊娠)致畸胎作用。 危险特性：易燃，其蒸气与空气可形成爆炸性混合物。遇明火、高热能引起燃烧爆炸。受高热分解产生有毒的腐蚀性烟气。与氧化剂接触会猛烈反应。其蒸气比空气重，能在较低处扩散到相当远的地方，遇明火会引着回燃。燃烧(分解)产物：一氧化碳、二氧化碳、氯化氢、光气。 3.现场应急监测方法: 4.实验室监测方法:
