Evaluates the Efficacy of Hygienic Handrub Products
BS EN 1500 : 2013 – Hygienic Handrub Method (phase 2, step 2)
EN 1500 specifies a test method to evaluate the efficacy of handrub products used in areas/situations where disinfection is medically indicated. This test determines whether a hygienic handrub product is capable of eliminating transient microflora from contaminated hands of volunteers.
Hand rub products are quite helpful in reducing transient microflora found on superficial layers of skin. Hospital environments are a significant reservoir of infections. With hand hygiene practices, chances of nosocomial infections can be controlled to a greater extent. Handrub products intended for use in medical area must possess strong microbicidal properties to reduce the risk of infections. EN 1500 standard provides a test method to assess efficacy of such hygienic handrubs before using them in real situations.
EN 1500 Test Conditions & Requirements
Mandatory test organisms – Escherichia coli K12
Subjects – 18-22 volunteers are required to perform the test analysis. Important to ensure that volunteers’ hands should not have any abrasions or cuts.
Contact times – Between 30-60 seconds or as per manufacturer’s recommendations.
EN 1500 Test Method
- Prior to microbial contamination, volunteer hands are washed to get rid of dirt and other impurities.
- In the next step, hands are immersed into microbial suspension and allowed to dry. Then the fingertips are dipped into tryptic soy broth (TSB) to determine pre-values of viable bacteria present on the hands.
- Contaminated hands are rubbed using handrub product sample for specific contact time.
- At the end of contact time, fingers are dipped into a neutralizing solution to recover remaining viable cells.
- A small portion of neutralizing extract is further plated and enumerated.
- Results are calculated by comparing the pre and post values of viable bacteria recovered from hands.
