Foreword

This standard refers to ASTM D5712-1999 "Determination of water-soluble proteins in natural rubber and its products - improved Lowry method Formulation. This standard is proposed and managed by the National Certification and Accreditation Administration. This standard was drafted. Ningbo Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China. The main drafters of this standard. Tong Lubo, Ge Xuanning. This standard is the first industry standard for entry-exit inspection and quarantine. Determination of latex protein in medical gloves for import and export

1 Scope

This standard specifies the method for determining the protein content of latex in medical gloves. This standard applies to the determination of latex protein content in medical gloves. The range of determination of latex protein content in this standard. 7μg/dm 2～200μg/dm 2.

2 Normative references

The terms in the following documents become the terms of this standard by reference to this standard. All dated references, followed by all Modifications (not including errata content) or revisions do not apply to this standard, however, parties to agreements based on this standard are encouraged to study Is it possible to use the latest version of these files?

3 Method summary

Latex protein in medical gloves and natural rubber products can be extracted from the buffer solution and precipitated to remove soluble interferences. The Lowry method measures the absorbance at a wavelength of 750 nm from a spectrophotometer.

4 Terms and definitions

The following terms and definitions apply to this standard. 4.1 The sodium hydroxide capacity (mL) used to dissolve the sample to extract the precipitate and the sodium hydroxide used to decompose the standard ovalbumin extract The ratio of capacity (mL). Note. For example, 5mL test extract, precipitated and dissolved with 1.25mL sodium hydroxide, standard egg protein is dissolved with sodium hydroxide, and its dissolved volume is also At 1.25 mL, the dilution rate of the test extract is the same as the dilution rate of the standard curve. 4.2 Latex proteins and polypeptides from natural rubber and its products. 4.3 Quantitative detection limit LOQ The lowest protein content that can be quantitatively measured and produces accurate results. The LOQ is set to a standard deviation of 10 times.
