THE HISTORY ISO 6330: 1984 – 1 st edition ISO 6330: 2000 – 2 nd edition ISO 6330: 2012 – 3 rd edition

WHY DO WE NEED THE STANDARD? Standard specifies domestic washing and drying procedures for textile testing. Washing procedures represent single domestic washes.

Why does the laundering is so important? - Dimensional stability - Colorfastness - Special properties (performance textiles)

WASHING PROCEDURES - 13 different washing procedures based on the use of the reference washing machine Type A: horizontal axis, front-loading type, - 11 procedures based on the use of the reference washing machine Type B: vertical axis, top-loading agitator type - 7 procedures based on the use of the reference washing machine Type C: vertical axis, top-loading pulsator type.

DRYING PROCEDURES Line dry, drip line dry, flat dry, drip flat dry, flat press and tumble dry.

TUMBLE DRYERS Type A 1 tumble dryer – Vented Type A 2 tumble dryer – Condenser Type A 3 tumble dryer – Large vented

WASHING BALLASTS Type I - 100 % Cotton ballast Type II - 50 % Cotton/50 % Polyester ballast Type III -100 % Polyester ballast

REAGENTS – 6 detergents are recommended WATER – hardness, pressure and inlet temperature are specified

WHY DO WE HAVE THE NEW STANDARD? - Wascators manufacturer introduced a new model, different to the …. . previous version - As the global document the standard was commonly used in Asia but the typical machine for that market was not specified - Version 2000 and amendment from 2008 were not clear on washing detergents - New (mild) washing programs were introduced for type A machines

THE DIFFERENCES? NEW WASHING MACHINES – TYPE A (Wascator) Horizontal axis, front-loading type.

NEW WASHING MACHINES – TYPE A Horizontal axis, front-loading type. - New dimensions and volume - All Wascators manufactured before 2002 do not conform to ISO 6330: 2012

THE DIFFERENCES? NEW WASHING MACHINES – TYPE B Vertical axis, top-loading agitator type.

THE DIFFERENCES? NEW WASHING MACHINES – TYPE B Vertical axis, top-loading agitator type. ISO 6330: 2000 recommended machines consist of a drum with an inner perforated basket 50 cm in diameter and 30 cm in depth

THE DIFFERENCES? NEW WASHING MACHINES – TYPE C Vertical axis, top-loading pulsator type. This is a new instrument for this standard.
