20 additional tests for Domestic use clear Guidance

Last updated on Tue, 02/08/2011 - 18:03

To provide clearer guidance on the chemical resistance of S range in domestic applications, SAINT-GOBAIN PAM has carried out 20 additional tests to the EN 877 Standard requirements on detergent products (floor cleaning product, laundry detergents…) and special products (stain remover, drain cleaner…) of common use.

The tests were carried out on samples, under the temperature of use recommended by the manufacturers and where it was relevant, up to 70°C since hot water is normally supplied in dwellings around 50 – 60°C.
After stopping the test, the pipes and fittings were washed immediately to eliminate any stains and the coatings and were examined with regard to blistering and rusting both according to ISO 4628-2 and 3. (Accepted levels according EN 877)

  • Concentrations are from experience or directly taken from the products technical specifications.
  • pH indicated is the one of the solution ( not that of the product before blending).
  Concentration pH solution q°C use q°C maxi Duration
Washing machine          
Phosphate free wash 2 ml/l 7,69 50 70 30 days
Stain remover 3 ml/l 7,65 50 70
Softener 2 ml/l 7,55 50 70
1+2 2 ml/l + 3 ml/l 7,66 50 70
1+3 2 ml/l + 3 ml/l 7,68 50 70

Washing up liquid 2 ml/l 7,65 50 70 30 days
Washing gel 3 g/l 9,83 65 _
Washing tablets 3 g/l 9,31 65 _
Cleaning products          
Surface cleaner 8 ml/l 8,21 50 70 30 days
Bleach 8 ml/l   Ambient  
WC cleaner          
Cleaning Gel 20 ml/l 5,45 Ambient _ 30 days
Drain cleaner          
Drain cleaner gel 0,33 ml/l 13 Ambient _ 4 days
Descaler          
Liquid descaler 80 ml/l 2,07 Ambient _ 30 days 

The duration of the test is considered equivalent to the extrapolation of a real chemical stress undergone during 7 or 10 years (a 10 to 15 min stress per day).
This test method however simulates a severe stress since the samples lies in direct contact with the solution, the temperature is being maintained and the test includes no rinsing over its duration.
