美国VHG标油总酸值标样是一种用于测量化学物质酸度的标准样品。它的酸值为3.0 mg KOH/g，使用的基质是烃类油。该标样符合ASTM-D664和D974标准。ASTM-D664是通过电位滴定法测量酸值，而ASTM-D974是通过颜色指示法测量酸值。这两个标准通常使用20克样品进行测试。这种标样广泛应用于变压器油等酸值在0.05 mg KOH/g至0.50 mg KOH/g之间的油品。另外，还有一个类似的标准ASTM-D3339，适用于较小样品的测试。 Acid Number (AN) Reference Standard是VHG Labs的酸值参考标准，包装规格为400克琥珀色玻璃瓶。它适用于根据ASTM D664/IP 177（通过电位滴定法）或ASTM D974（通过颜色指示法）测定石油产品中的酸值。

The standard range of applications is for oils with an AN between 0.05 mg KOH/g and 0.50 mg KOH/g, which is applicable to the transformer oils. ASTM D3339 is also similar to ASTM D974, but is designed for use on smaller oil samples. ASTM D974 and D664 roughly use a 20 g sample; ASTM D3339 uses a 2.0 g sample, as shown in Table 2. Table 3.

In chemistry, acid value (AV, acid number, neutralization number or acidity) is a number used to quantify the acidity of a given chemical substance. It is the quantity of base (usually potassium hydroxide (KOH)), expressed as milligrams of KOH required to neutralize the acidic constituents in 1 gram of a sample… The acid number is a measure of the number of carboxylic acid groups (-C(=O)OH …
