  • Domestic washing EN6330
  • Industrial ISO15797 / NFPA 2113
  • Dry cleaning

Washing procedures and domestic drying textiles (PPE) are:

Two types of washing machines, and 10 to 11 washing procedures. 5 drying procedures and reference detergents. And the ISO standard that specifies the instructions to follow for its labeling is ISO 3758.

  • ISO 3175 Dry cleaning tests with solvents – Hydrocarbons

An important element to note is that the hydrocarbon is suitable for The cleaning of most textiles, however, as less volatile is the solvent in the cleaning requires higher drying temperatures or a longer drying cycle.

In the case of fabric materials that are sensitive to heat, or a material with certain adhesives, their performance may be affected by prolonged exposure or higher temperature.

  • ISO 3175 Wet cleaning tests

And the ISO standard that specifies the corresponding pictograms for labeling maintainers is the ISO3758.
