# Chas Accreditation
by [**Neil Brook**](https://www.inoxpassivation.co.uk/blog/author/neil-brook) on January 17, 2020
We are very pleased to kick off the New Year by being accredited with CHAS Premium.
The metal finishing / chemical cleaning industry has various challenges in Health & Safety, Environmental, Quality and Financials. This accreditation means that we are able to demonstrate full PAS 91 compliance in each of them.
Having these fundamentals in place helps to demonstrate our commitment to effectively managing our processes, whilst providing a sound footing for ongoing improvement.
For more details on what is required for accreditation, click [here](http://www.chas.co.uk/)
## What We Do
### Stainless Steel passivation
We are specialists in the onsite chemical treatment of stainless steel. From pre-commissioning cleaning, passivation and validation, to the ongoing maintenance and restoration of in-service equipment and surfaces
### Oxygen Cleaning
An oxygen-enriched /pressurized environment will result in much more vigorous combustion (potentially explosive) and can cause ignition in materials that would not normally burn in atmospheric air.
### Stainless Steel pickling
Successful pickling is a function of acid strength, acid temperature and contact time. All three variables can be manipulated (within reason) in order to suit the grade of stainless steel, the component being processed and of course, the client’s schedule.
Having the premium accreditation is just the first of many standards that the business will be striving to achieve this year. We provide real solutions to many industries and setting standards above and beyond the competition is our primary focus.
NEIL BROOK
Director
