Workbenches testnig be of convenient working height tedting people can work standing up. The worktops should be cms in depth. The worktops should be covered in easily cleaned laminate similar material.
A selection of cupboards and drawers should be available under the worktops. Conditioning Shelves of non-rusting mesh measuring 60 x 60 cms should be built under some of the worktops. These should be manufactured so that the can be pulled out easily to allow the technicians to place test specimens on them in a crease-free state.
A workbench with cupboards and Conditioning Shelves below it is almost essential to allow the technicians to sit down whilst preparing test specimens. It is desirable to make this bench as large as possible so that a 2 metre length off fabric can be unrolled, full width, on it.
This will allow the technicians to inspect it and also to select the best and correct location from which to take cut the test specimens. This will have to be connected by insulated copper pipes to a condenser that is located outside the Conditioned environment.
In many cases this will be located outside the building. The supplier of the air-conditioning system will confirm the maximum length of pipe that is allowed between the two units and the location of the Conditioned Laboratory must take this into account.
This should be sheltered from direct sunlight and should be located in a place where it is easily accessed so that maintenance can be carried out easily. Generally it is not good to locate the condenser on the roof and situating the laboratory several floors above ground level in a high rise building may also cause problems with the operation and servicing of the condenser.
Most suitable air conditioning systems will require a supply of water, the quality of which will be specified by the supplier. It will also need a small diameter drain pipe to carry waste water away from the unit. Working practices that help to maintain the integrity of the environmental conditions must be instigated from the first day of opening the laboratory facility.
This means that any activity that can change the environmental conditions should be minimised. When the system is operating 'in equilibrium' the instruments and technicians working in it should not have any adverse affect on the environment.
It can be understood from this that it is vital to plan how the Conditioned Laboratory will be used from the very beginning and how the technicians must be trained in the correct ways of working from day one.
Every time the doors are opened the conditions are disturbed so the Conditioned Laboratory should not have instruments in it which do not have to be in that environment - a good example is a spectrophotometer; this is something that is used very frequently and this will automatically mean that technicians are coming in and out of the room many times in order to use it.
The spectrophotometer should be located elsewhere to avoid the problems this causes. The double doors should have automatic closers fitted to them so that the technicians do not have to remember to close them themselves. There is one basic rule for the use of these double door arrangements and this is that never should both doors be open at the same time.
Cleanliness is important in any workplace. If it is necessary to wash floors and work-surfaces this should always be done at a time when testing is not in progress so that the environment is not disturbed by the water that is used and the length of time it takes to dry afterwards.
Early planning is vital to ensure that the project proceeds correctly - the cost involved in having to make serious changes to the construction or the air-conditioning system if something goes wrong and the environment cannot be controlled can be enormous and carrying out the work can be very disruptive.
The information given are based on principles that are proven worldwide to have provided the conditions that are acceptable to editors and Auditors and, most critically, to provide facilities where there is the best possibility to generate accurate and reproducible test results.
If the plan is to become an Accredited laboratory that can self certify it's products before shipping, then it will minimise external testing costs, reduce delays and make a strong, positive statement about your company's intentions to your customers.
If projected for a future purchase, then this must be taken into account when the Conditioned Laboratory is designed and the air-conditioning system is bought. Machines such as this generate heat and hot exhaust air has to be piped away from them.
If the system is designed correctly it will handle this without a problem; if allowance is not made for this then it may be impossible to maintain the correct environment in the laboratory when the light fastness tester is operating.
Thinking forward about this kind of issue is a very important part of the planning that goes into the building of all of the Laboratory but it is most critical in the Conditioned Laboratory because the of the precise control that is required in order to get the necessary results.

Why is a Conditioned Laboratory necessary? All textiles absorb specific amounts of moisture from the environment in which they are located.
Doing this ensures that: The results correlate with those from other Laboratories that are testing the same fabric or garment. When testing the same product on a regular basis, maybe 2 or 3 times a week, the results of each test will be accurate so that a clear picture of how the product performs is obtained.
Constructing your laboratory. The following must be taken into account; Location of the room Surrounding ambient conditions Volume and size of room Average number of people who will work in it and their entries and exits Contents of the room and their potential to alter the temperature i.
heat generated by computers, lights, motors etc Position of work benches and furnishings At the end of the exercise a detailed specification will have been arrived at for the conditioning unit itself together with any ducting and circulation fans necessary to ensure that all parts of the room are the same.
What to consider when building the Conditioned Room:. Location If possible it should be located on the ground floor. Insulation To provide insulation from the surrounding conditions all of the walls should be double walls with an air gap between them.
Windows Ideally there should be no windows, but this can make the working conditions quite unpleasant for the technicians involved. Water Normally water is not required or desirable in the Conditioned Laboratory because it interferes with the equilibrium of the air conditioning system, however many laboratories prefer to install a small hand-washing basin.
Floor The floor should be ceramic tiled or painted with a compound to reduce dust and make cleaning easier.
Lighting Lighting should be with normal fluorescent tubes and should be of a level that allows the technicians to carry out detailed work, such as counting ends and picks comfortably and reliably.
Workbenches Workbenches should be of convenient working height so people can work standing up. Air-conditioning system This will have to be connected by insulated copper pipes to a condenser that is located outside the Conditioned environment.
Outside Condenser This should be sheltered from direct sunlight and should be located in a place where it is easily accessed so that maintenance can be carried out easily. Appropriate working practices.
Opening doors Every time the doors are opened the conditions are disturbed so the Conditioned Laboratory should not have instruments in it which do not have to be in that environment - a good example is a spectrophotometer; this is something that is used very frequently and this will automatically mean that technicians are coming in and out of the room many times in order to use it.
