BS EN 13704:2002

Quantitative suspension test for the evaluation of sporicidal activity of chemical disinfectants used in food, industrial, domestic and institutional areas. Not suited in situations where disinfection is medically indicated or when products are used on living tissues with the exception for hand hygiene in the above instances.

Products that can be tested
Chemical disinfectant products that form homogenous, physically stable preparations in hard water for use in the above instances.

Description of Test

  • A test suspension of Bacillus subtilis spores in a solution of interfering substance, simulating clean conditions, is added to a prepared sample of the product under test diluted in hard water.
  • The mixture is maintained at 20°C ± 1°C for 60 minutes ± 10 seconds.
  • At the end of the contact time, a portion is taken and the sporicidal action in this portion is immediatedly neutralized or suppressed by a validated method.
  • The number of surviving bacterial spores in each sample are determined. The reduction in viable counts is calculated.

Third Party Validation
On passing this test, the product can be labelled as tested by airmid healthgroup to BS EN 13704:2002 in support of any claim relating to the test and data received.

Turnaround Time
4 weeks from receipt of samples
