Clean Room Testing Services

Cleanrooms play critical roles in maintaining contamination free production environments for critical processes. To ensure your cleanroom is working as designed it is essential that a well planned and executed cleanroom testing and certification and maintenance program is undertaken for operation and regulatory compliance. APT cleanroom testing offers clean room testing and clean room certification.

We will also take time to explain the process and reportage to ensuring that you fully understand the testing process and your final results.

ISO Standard 14644-1: 1999 has recently been updated to the 2015 version. It requires changes to sampling procedures and monitoring plans for cleanrooms and clean zones, all of which is outlined in the revised ISO 14644-1:2015 standard. Organisations will be required to redefine their validation sampling plans and data evaluation and will obviously affect the clean room testing reportage.

The updated ISO 14644-1:2015, specifies the classification of air cleanliness in terms of concentration of airborne particles in cleanrooms and clean zones and is the first significant revision since its original release in 1999.

The major change from ISO 14644-1:1999 publication is the adoption of a more consistent statistical approach to the selection and number of sampling locations; and thereafter the evaluation of the data collected.

This new approach allows each location to be treated independently with at least a 95 % level of confidence that at least 90 % of the cleanroom or clean zone areas will comply with the maximum particle concentration limit for the target class of air cleanliness. Cleanroom users will have to make changes to the cleanroom validation procedures to meet the requirements laid out in the latest version of ISO 14644-1:2015 and ISO 14644-2:2015.  It is possible that the revised standard will require cleanroom owners to make changes to their cleanroom to ensure they continue to achieve the required classification and remain compliant.

The Right Taking Care of the Plumbing Process Now

It can be very hard to find a good installer. Those who are good are in great demand, and they are not available all the time because they have many works.Unfortunately, you can also drop over some installers who try to cheat you, and who do the work of screwing up by failing to assemble or by installing the device due to malfunctions of the plant immediately or in time. You can trust on the best in plumber singapore for the best result.

What you will learn from this article:

You will find out in this article how to guard the installers who are not serious and do not do the good job, and how to make a good plumber.

Here are the steps:

  1. Verify if ISCIR is authorized

If the installer is working on a company, check if it has an ISCIR authorization .Especially if you have to do the heating plant. Also check if he / she haveschooling, a diploma or a specialized course. You can find the names of the authorized companies on the ISCIR website.

  1. Find your name and phone number

Do a search on Google to find recommendations or opinions about it. In some cases, you can also find pictures of your work. Read the Facebook or Twitter page to see how it interacts with clients and people in general. If you want some details about me you can find my facebook page here.

  1. Ask him how long he works in this area
  • You can tell by his age whether he will disappear after finishing your work or not.
  • Theoretically, firms or people with a good reputation should last, and those with a reputed reputation should disappear from the market.
  • Unfortunately, there is no rule that always applies.
  1. Ask for the second price offer from another installer

And make sure you compare apples to apples. A plumber can ask for a very small workmanship, but his work will not last long.

Ask the best in electrician singapore for the higher price, why his price is at that level to figure out what the difference is.

  1. Ask about the warranty

How much is the warranty, 3month, 6month, 1an, 2an? Does the money back if it is the case? Release a written warranty and invoice?

Plumbers who rely on good services will have no trouble answering these questions.

  1. The price on the phone may not be correct

A plumber who gives you the price of the job on the phone is not necessarily a good installer. Some installers prefer to bid only after seeing the job on site and can very well estimate what materials and workmanship are needed.

And from the perspective of the plumber and the client, there is nothing worse than saying that the work costs X lei and gets to work to find that it will cost YI lei due to some factors.
