Scope Of Materials Testing Across The Building And Construction Industry

Material testing is a crucial aspect in many industrial sectors. It is particularly important to both, the building and construction sector and the automobile manufacturing industry. If proper materials testing are not conducted across the mentioned commercial sectors, life of the public could be in jeopardy. As far as the construction industry is concerned this kind of testing is even more important. It may happen that unscrupulous builders use inferior grade of materials, without proper testing, to construct buildings and bridges. Such possibility could result in collapsing of the structure any moment and fatally injuring hundreds of people in the process. To avoid such calamities, construction firms invariably require seeking help of dependable testing laboratories to ensure the materials they are using in the construction process are of superior grade.

Proper materials testing should be underway as soon as the construction work commences. Ideally, the testing should be conducted at various phases of a project. This helps ensuring the ingredients being used are of superior quality and the final structure that is coming up is hardy and durable. It is because of this reason that the aspects of construction materials testing and structural analysis are usually clubbed together in the building and construction sector. Testing of the construction materials requires specialized knowledge. As such, imparting this knowledge is one of the crucial objectives of civil engineering education. Gauging the strength, elasticity and flexibility of specimens is common in this field of work.

The specialized service of construction materials testing requires hi-end technological expertise. The laboratories that provide the range of service have to deal with an extensive range of smart tools and equipments based on cutting-edge technology. The workforce across the commercial sector mostly comprises of scientists, engineers and well-trained professionals. Without an expert and technically sound workforce, it is indeed difficult for laboratories to provide impeccable service. In order to provide greater convenience to the customers, the materials testing laboratories work closely with the construction management teams. This helps the experts to anticipate as well as minimize problems that could withhold the work progress.

Teaming up with adept materials testing laboratories not only helps builders to complete their projects within stipulated deadlines. It also helps them to complete the work according to various technical and environmental norms. The specialized service providing sector caters to a wide range of customers which include contractors, developers, consultants, government corporations, municipalities and others. Apart from testing, the category of laboratories usually provides certification and consultancy services as well. Professionals working in the vocation require keeping themselves constantly upgraded on the latest breakthroughs occurring in the industry.

In fact, quality assurance is one of the prominent factors because of which the clients approach these testing laboratories. Usually, the challenge of these laboratories lies in developing extensive and customized quality assurance techniques that will meet specific requirements of the clients. Business is flowing in from all directions into the sector. Immense commercial prospect has made this line of service unbelievably competitive in the recent times. In order survive into this turbulent situation, businesses require to quote competitive pricing to enjoy an edge over the competitors.

Technical Steps to Frame Fitting

When selecting a frame, how do you ensure the frame fits properly? Do you use a technical guideline or rely on customer feedback? As the eyewear industry expands the boundaries of frame design, eyecare professionals need to adapt the characteristics of the frame fitting process to the changing climate of frame shapes and styles.

The technical steps to frame fitting is a guideline that will allow each user the ability to quickly identify a proper fit, while incorporating the needed fashion and function benefits a customer requires.

A technical fit will rely on five components:

1) Face shape;
2) Frame width;
3) Bridge style and size;
4) Temple length; and
5) Lifestyle.

Each of these components plays a vital role in helping choose the right frame for your customer.

The Five Components to a Technical Frame Fit:

1). Face Shape- Everyone has different face shapes, sizes, and features and this is why frame manufacturers produce many different types and styles of frames. The trick is to find a frame that uses the customer’s features to benefit their fashion needs and overall appearance. Choosing a frame based on face shape is a subjective process because what may be considered appropriate based on facial shape may not be the look or style the customer wants to wear. Below is a chart that will help identify which style of frame should be considered when looking at the shape of the customer’s face:

Oval face – Normal shape – Most shapes will be suitable

Oblong face – Long shape – Deep frame, preferably with a low temple

Round face – Wide shape – Relatively narrow frame, preferably with a high temple

Square face – Wide shape – Same criteria as a round face

Triangular face – Erect triangle shape – Width of frame should equal lower widest part of facial area

Diamond face – Inverted triangle shape – Lighter looking frame (metal or rimless)

2). Frame Width- A technical detail that matches the width of the frame to the customer’s face. The frame front should be wide enough to allow for a generally straight path from the end of the frame to the ear. Frames that are too wide or too narrow can cause the customer discomfort, and can affect the structure of the frame, not allowing the frame to stay in adjustment. A simple way to determine if a frame is too wide, too narrow, or just right, is the position of the eye in the frame.

To Wide: If a frame is too wide for a person’s face, the customer’s eye position will be near the bridge of the frame. When this occurs, the customer will appear cross-eyed and there will be a significant amount of lens material towards the temple side of the frame. While this type of fit could work in products that are designed to provide an oversized appearance (i.e. sunwear), it is not recommended for clear lens designs.

To Narrow: If a frame is too narrow for a person’s face, you will have two key indicators: the eye position will be towards the temple side of the lens, and the temples will be touching the side of the face well before the ear, producing a “squeezed” look on the face. When this occurs, it is best to identify the eye size of the frame and avoid other frames that are below that eye size.

Just Right: If the frame width is correct, the eye will be positioned in the center of the lens and will produce a direct path for the temple from the frame front to the ear. If the position of the eye is not exactly centered, you should have the eyes positioned slightly inward towards the bridge instead of outward towards the temple. In cases where a customer has a narrow pupillary distance (PD), look at the position of the eyes in the lens first and determine if an adjustment to the temples can reduce or relieve any squeezing appearance that may be present.

3). Bridge Size and Style- Once you have determined a good width for the customer’s face, you now need to be concerned with the bridge style and size. This section is critical because the bridge supports 90% of the frame and lens weight. So a good bridge fit will help produce an overall comfortable fit.

The primary factor that determines a good bridge fit from a bad bridge fit is the amount of surface resting flush upon the nose. The more bridge surface resting on the nose, the more weight is distributed equally, the more comfortable the frame will feel. Conversely, if there is less distribution of weight on the nose, or the bridge sits on a lesser area, then the frame will feel uncomfortable and will create pain and irritation for the customer. While there are techniques and tricks that can alter and improve the fit of a bridge, there is no substitute for selecting a bridge that initially provides a good fit.

4). Temple Length – Now that we have a good understanding about how the frames rest upon our face, we need to start understanding how the frames hold themselves in place. The bridge may support 90% of the frames weight, but the temples will most likely require about 90% of the frames adjustments. Just like the bridge, temples that fit well are paramount when discussing the overall comfort and fit of a frame. A well-chosen bridge will often fit a patient’s nose with little or no adjustment, while a pair of temples will always require some type of custom adjustment to fit each customer individually.

Like the correct bridge fit, a correct temple fit relies on placing the maximum amount of temple surface over the greatest area. When you fit a frame, the temple weight should feel evenly displaced between the back of the ear and the front of the frame. When a frame becomes uncomfortable, generally it is caused by a concentration of all the holding power the temple has on a limited area.

Another key indicator of proper temple length is identifying where the bend of the temple takes place. A proper temple bend will begin immediately after the top base of the ear (this is where the ear and skull connect) and will contour to the skull.

If a temple length is too short, you will notice the bend of the temple begin prior to the base of the ear, placing maximum pressure on the backside of the ear. When a temple appears to be too short for the customer, it will always be best to select a different temple length (if available) or select a different frame altogether. Trying an adjustment to a temple that is too short will be time consuming and ultimately will leave the customer with an uncomfortable fit.

If a temple length is too long, you will notice the bend of the temple begin after the base of the ear, thus making the frame appear unstable and loose. When a temple is considered to be too long for the wearer, an adjustment may be performed to properly fit the temple to the wearer’s skull. If you had to choose between a temple being too long or too short, it would always be best to have more frame material to work with than less.

5). Lifestyle – In determining what type, style, and shape frame a customer should be fit into, you should ask the customer how they intend to use their new frames. This information will allow you to direct the customer to select the appropriate frame type that allows them to use their product in a fashion that does not cause the product or potentially the customer, harm. This can be achieved by asking questions to learn more about the customer and their hobbies, interests, and work. Again, we do not want to fit and ultimately sell a product that cannot meet the demands and abuse each individual might place on their product. The more information you can receive from the customer about their intended use of the product, the better equipped you can be to help select a frame that is right for them.

Other Items to Consider when Frame Fitting:

While the five tips above will help you produce the best frame fit for your customer, there are other options to consider when completing the fitting process: a customer’s prescription strength, lens types (progressive addition lenses, bifocals, single vision, etc.), lens materials, and facial measurements (segment heights, pupillary distances, etc.). Failing to consider these options when fitting a customer will produce a product that will not meet the performance needs to achieve visual satisfaction and the fashion demands of the customer.

By understanding and implementing these five technical fitting tips you will be able to help your customer’s choose a frame that fits properly, and handles the demands of their lifestyle.

Dental Laboratories – What Makes A Competitive And Safe One

Dental laboratories are key in the creation of a perfect smile for millions of people who are looking for one. Important items used for dental care are made in these facilities. Bridges, caps, fillings, laminates and veneers for the teeth are mass-produced here.

As we all know, the items mentioned above need to resemble and function like real pearly whites. This is because their imperfect manufacture may cause inconvenience and further problems to their users. Even though their manufacture involves different machines, the technicians who will be in charge must exude great skills. Through this quality end products can be expected.

Dental laboratory technology includes cutting-edge procedures like CAD-CAM imaging, computer- based scanning, milling techniques and restoration planning. All these come with a quite expensive cost which not all service providers can afford. Because of this, some choose to hire highly skilled technicians who can come up with the best output instead of investing in the latest technology. Needless to say, patients looking for the best service would always regard a combination of competitive technicians and facilities.

Have you ever experienced wearing an ill-fitting dentures, retainers or fillings? These are most probably made the traditional way – manual creation with the use of mouldings. Modern dental laboratories make use of personalized computer programs which take individual measurements in millimetres to ensure accuracy. This restricts the errors which technicians might make. Therefore, shifting of dentures during chewing, laughing or sneezing is avoided. Additionally, their make is more durable.

Hygiene and safety are two other factors which are considered when these facilities are talked about. Unhygienic labs can cause the spread of deadly diseases among patients. Examples of these are tuberculosis, hepatitis B virus and even AIDS. This is because a variety of microorganisms are released from the mouth when dental procedures are done. These may be surgical or non-surgical.

It is important then that absolute decontamination of the equipment and tools used is observed. This can be achieved by taking note of the standards in the proper sterilization and storage of all the items. A safe way to use each of them is advisable too. Doing the opposite can endanger the health of the dentists, assisting technicians and patients.

Wearing of gloves may seem like a very trivial practice but it is the most important of all. When dentists and technicians wear gloves, contact with the body fluids of the patients is avoided. In the same manner, spread of bacteria and viruses. Disposable and single use gloves are ideal for this purpose.

Dental laboratories may also hold harmful substances which can be hazardous to dentists, technicians and patients. One of these is the silica dust. This is important in the creation of artificial teeth. When inhaled in large amounts, silica dust can cause troubles to the lungs like cancer. Exposure to radiation and loud noises resulting from the creation of dental items is also a possible cause of dangers. Wearing of protective gears like ear caps, goggles and shoes would be very helpful in preventing life-threatening dangers.
