ISO 12243:2003规定了医用天然橡胶（NR）手套中水可提取蛋白质含量的测定方法。该方法可能适用于NR乳胶制品中可提取蛋白质的测定；然而，提取程序和时间尚未得到验证，并将因待检测物品的类型而异。还有其他测定医用手套中特定蛋白质的方法（见附件），但它们不具有普遍适用性。 本国际标准仅涉及分析方法。它与取样无关，也无意解决获得的数值或标签要求的安全影响。

ISO 12243:2003 specifies a method for the determination of the amount of water-extractable protein in natural rubber (NR) gloves for medical use. The method is potentially suitable for the determination of extractable protein in other articles made from NR latex; however the extraction procedures and times have not been validated and will vary with the type of article to be tested. Other methods for the determination of specific proteins in medical gloves exist (these are described in an annex) but they are not of general applicability. This International Standard is concerned solely with the method of assay. It is not concerned with sampling nor does it purport to address the safety implications of the values obtained or requirements for labelling.
