ISO 6330:2012 Update

11 July 2012

Following our previous post "Major changes to ISO 6330 coming soon!" we thought it was time for an update.

Technical Manager Peter Goodwin discusses the changes in more detail....

The new standard was published in April, earlier than expected, and we followed this with our leaflet "ISO 6330:2012 - What does it mean ?". This caused some controversy on LinkedIn but in the main the reaction was one of genuine interest from users.

The main focus of questions has centred around Wascators, washing programmes, detergents and ballast (makeweights).


The Wascator FOM71 model washing machines are the most recognised "industry standard" or "reference" washing machines used by customers testing to ISO 6330. The machines were first marketed in 1969, before many of you were a sparkle in your father's eye! This means they are ubiquitous and of varying ages with some still going strong.

Users of older machines were concerned about whether or not their machine was still compliant with ISO 6330:2012. Broadly speaking, models "S" and "MP" are no longer compliant because they cannot make the new "mild" agitation required for procedures 6M, 5M, 4M and 3M. (The last procedure has no connection with the Minnesota Mining & Manufacturing Company!) However, the "S" and "MP" models can still be used for procedures requiring normal (N) or gentle (G) agitation.

Models "S" and "MP" cannot be upgraded to ensure full compliance with ISO 6330:2012. We have also been advised by the producer that support for these two older models will be withdrawn subject to availability of spare parts.

The more recent "MP/Lab" and "CLS" models are fully compliant with ISO 6330:2012.

Washing Programmes

The new washing programmes will be available very soon, we are testing them right now!

They will be available on a locked smart card for the "CLS" and a returnable (loan) cassette for the "MP/Lab".

Programmes for the "S" and "MP" are not available but users can prepare their own punched cards or enter their own programmes.


Currently, only the 100% polyester makeweights are available from James Heal. If there is a substantial demand for the 100% cotton and 50/50 polyester/cotton options then we may also consider producing these.


The main area of enquiry has been which reference detergent number corresponds with the previous reference numbers and then relating this to the colloquial descriptions used. The table below should clarify this.
