Floor test meaning

Floor Flatness and Joints Understanding F-number requirements and jointing for commercial and industrial floors Updated February 12, 2021 In the bad old days, concrete floors were specified without knowing how to actually measure what was being specified. The old flatness requirements of ¼ inch in 10 feet, for example, left so much up to interpretation that it was basically useless. Anyone could measure almost any floor and pass it or fail it depending on how the measurement was applied and what they wanted to happen. Can't you just see a poorly trained testing technician with an old warped 10-foot long 2x4 bending down with a ruler to measure the gap between the straightedge and the floor? Then saying, this floor is no good! But, today we have F-numbers for flatness and levelness and ACI 302.1R, Guide for Concrete Floor and Slab Construction, that tells us when and how to apply the F number specifications. Floor Flatness & Levelness One of the things that distinguishes a high tolerance floor is its F-number requirement. F-numbers were developed in the 1980s to provide a systematic, quantitative way to indicate the flatness and levelness of a concrete floor. The higher the F-number, the flatter or more level the floor. There are actually three F-numbers that are used for concrete floors, depending on whether the floor will have a random traffic pattern or defined traffic aisles. F-min is measured using a traveling profileograph, which simulates the wheel pattern of a high-...

CHENNAI: V K Sasikala’s conviction and the ever-changing political scenario in President’s Rule Article 356 of the Indian Constitution states that a governor can request for the President to take control of the state -- President’s Rule -- if he feels that the state machinery has broken down. Since the President is usually appointed by the Centre, President’s Rule may be looked as the Centre running the state. In order to protect the federal structure and prevent misuse of power by the Centre, the Supreme Court ruled that the constitutional machinery should be tested on the floor of the Legislative Assembly of the state by votes. Former Secretary-General of the Lok Sabha, Subash Kashyap, explains: What is floor test? A chief minister appointed by the governor can be asked to prove his majority in case of doubt. In the 2016 elections, AIADMK won 134 out of 234 seats. With absolute majority, there were no questions asked and AIADMK leader J Jayalalithaa became the chief minister and formed the government. In situations where the majority can be questioned (for instance, when there is a coalition government), the governor may ask the chief minister to prove his/ majority in the House. In that case, the chief minister has to move a vote of confidence and win a majority among those present and voting. What is composite floor test? If there is more than one person staking claim to form the government and the majority is not clear the governor may call for a special session to se...

Eknath Shinde, the leader of the Shiv Sena rebel block, on Wednesday said they will reach Mumbai tomorrow. He said the block has the support of 50 MLAs, including more than 40 Sena MLAs. He said he has the two-third majority, enough to topple the Uddhav Thackeray government and circumvent the anti-defection law. "We will reach Mumbai tomorrow. 50 MLAs are with us. We've 2/3 majority. We are not worried about any floor test. We will pass all things and no one can stop us. In democracy majority matters and we have that," Shinde said in Guwahati. The Deputy Speaker of the Maharashtra Assembly has sent disqualification notices to 16 rebel MLAs, including Shinde. They moved the Supreme Court last week against the decision. The court has given them time till July 12 to respond to the notice. Prabhu's counsel said the floor test was illegal as it cannot include those facing disqualification. "I am only requesting a listing today evening. Otherwise, the matter will become infructuous. Votes which cannot be counted will be counted. The entire exercise will be futile," the counsel added. Can Uddhav Thackeray pass the floor test tomorrow? If Uddhav Thackeray takes tomorrow, going by the current calculation, he will likely lose. Shinde reportedly has the support of 40 MLAs. This means Thackeray's support base in the assembly has shrunk to 15. The MVA government has 169 MLAs in the Assembly whose half-way mark is 144. If as many MLAs vote against Thackeray, his government will lose the...

In research, a floor effect (sometimes called a “basement effect”) occurs when there is some lower limit on a survey or questionnaire and a large percentage of respondents score near this lower limit. The opposite of this is known as a A floor effect can cause a variety of problems including: • It makes it difficult to get an accurate • It makes it difficult to get an accurate • It makes it difficult to rank individuals according to score. • It makes it difficult to compare the means between two groups. This tutorial provides several examples of floor effects, details on why they’re problematic, and ways to prevent them from occurring. Floor Effect Examples The following examples illustrate scenarios where floor effects may occur in research. Example 1: A Questionnaire on Income. Suppose researchers want to understand the distribution of household incomes in a particular neighborhood so they create a questionnaire to give to each household. Since they want to prevent $30k or less. In this case, even if households make far less than $30k per year, they will be grouped into the $30k or less group. If many households fall into this group and if many households make far less than this amount, then researchers will not actually get an accurate idea of the distribution of household income. Example 2: A Difficult IQ Exam Suppose a 1st grade teacher administers an IQ exam to her students that is actually designed for adults. More than likely, each student will score at or near the...

When predicting the performance of a laid floor's surface and/or system under simulated rolling loads to ASTM C627, a rolling load floor testing based on the Robinson-Type Floor Testing machine is commonly used. The test was initially designed for tiles; however the Robinson Floor Test can also be applied to most hard-surface flooring including; wood, marble, stone, slate, laminate, vinyl, and rubber. Using our Robinson-Type Floor Testing machine, we are able to conduct both on-site and laboratory testing. Outcomes of this testing include: • The durability assessment of newly laid flooring surfaces, which ensures they meet the required level • Highlighting installation of material manufacturing faults • Determining whether problematic flooring surfaces are meeting the required performance levels. Rolling load floor testing benefits include: • Being the only standardized method of flooring surface and flooring system performance, thus generating reliable data and results • The ability to differentiate your products performance from un-tested competitors’ products • Endorsed product specification modifications, which potentially leads to retrospective financial savings if specification adjustments are subsequently unsuitable. The testing is comprised of a three-wheeled rig which rotates at a predetermined speed, duration, loading and wheel type. We offer 14 different test schedules which are outlined below. Cycle Wheel Type Weight (kg) Duration (h) Revolutions Per Cycle 1 so...

Put simply, a test fit is a floor plan used to confirm that the stated needs and requirements can be accommodated within a specificspace. If your program dictates that you need 25 work stations, 3 conference rooms, a large reception area and a kitchen,a test fit will tell you if the space that you are looking at will be able to accommodate these needs. Typically, the landlord pays for a test fit. As a tenant, it is best to understand the criteria for your office program as well as possible in order to get an accurate test fit. Growth projections should always be factored in when doing a test fit. Can the space accommodate your company’s plans for growth? Space planning takes a much more in-depth look at your space. Here, the design professional will block out interior special areas, define circulation patterns and develop plans and layouts for furniture and equipment placement. Where a test fit will literally test to see if your needs can be met within a space, a space plan will elaborate on your space and what it will look and feel like. The tenant’s design parameters and project goals are built into space planning. Space planning accommodates for work flows, image and atmosphere, efficiency, interior details and materials and even FF&E. The space plan is where you will really begin to understand how your space will present to your employees. The difference between a test fit and a space plan is really the level of thorough detail.

Slip Resistance Testing Standards in 2023 Updated December 28, 2022 Sotter Engineering Corporation, Mission Viejo, CA USA Please click on At present, the pendulum DCOF slip resistance tester is the most useful and reliable floor friction test device (tribometer) to aid in accident prevention. The SlipAlert Tribometer, (now known as iAlert), BOT-3000E and Tortus tribometer are also useful tools in assessing floor friction, although each has certain drawbacks which make them less reliable than the pendulum dynamic coefficient of friction tester. Each of the four instruments has its own appropriate safety standard(s), e.g. 36, 0.42, or 0.50 for a level floor. The information below discusses these slip resistance test instruments and slip test safety standards as well as some others that have been used. Safety Direct America can run The basics: to assess slip-related safety we need (1) a published, peer-reviewed slip resistance test method, and (2) a minimum numerical safety criterion for each individual test method, e.g. 36, 0.42, R12, 0.50, 0.60, etc. to apply to the slip test results. Anyone who claims that there is a “generic coefficient of friction value that is considered safe”, such as 0.50, is completely misinformed and seemingly does not have a rudimentary understanding of physics or their stated field of “expertise”. People spreading misinformation such as this are usually full-time American courtroom “experts” who specialize in manipulating juries, and they often le...
