Indoor fitness equipment to detect major EU standards EN 957, American ASTM F1250, Japan JIS T1214, AS 4092, of which the EU developed the most complete and rigorous EN 957 is the most commonly used foreign buyers require manufacturers the design and production of its product safety standards. We have to EN 957 for the spindle to introduce indoor fitness equipment safety inspection and testing.
Indoor fitness equipment to detect major EU standards EN 957, American ASTM F1250, Japan JIS T1214, AS 4092, of which the EU developed the most complete and rigorous EN 957 is the most commonly used foreign buyers require manufacturers the design and production of its product safety standards. We have to EN 957 for the spindle to introduce indoor fitness equipment safety inspection and testing.
In the EN 957, Part 1 is a universal norm, pan for all the indoor fitness equipment; Part 2 and Part 4, respectively, define and regulate the strength training equipment, strength training sets of safety requirements; Part 5 is part of Fitness specific norms bike; Part 6 for specific standard treadmill; Part 7 are specific criteria used rowing machine; Part 8 includes a stepper, stair climber and climbing machine; Part 9 belong to a particular standard elliptical machine. Where EN 957 Part 2 (strength training equipment) in 2003 with the new revision, EN 957 Part 9 (elliptical machine) is to become an official standard in 2003. It is worth mentioning that, EN 957 does not cover equipment used by children as well as equipment for medical purposes.
Here, we are not against the individual indoor fitness equipment one by one explanation, but the standard requirements of its safety inspection area is divided into: safety testing, detection of static and dynamic tests do a comprehensive introduction.
Security agencies and anti-lock mechanism is often used in security checks muscle / strength training equipment, security agencies inside, especially for emergency stop devices more stringent requirements, such as a treadmill with the relevant provisions of the emergency stop switch and emergency off measure.
Safety Inspection consists of several parts of the external structure inspection, security agencies and anti-lock mechanism. Inspection external structure
(1) endanger the safety of users of the shear point and pulled into the spot.
(2) to prevent stretching of the hands and feet into points.
(3) the protection of sharp edges and corners.
(4) temperature rise test.
(5) the cumulative weight of the safety inspection of five parts.
(1), (2), (3) three-part almost all fitness equipment must be included in the test. Pull the point of the test is often used to test some of the test finger or foot to check that this part of the essential reference EN 71 and EN 292 test finger relevant regulations.
Temperature test is common in exercise bike, treadmill and other aerobic type exercise equipment, fitness equipment in some endurance test will measure the user can contact the highest temperature of the surface. The cumulative weight of the safety inspection is often used in the muscle / strength training equipment, as well as the placement of the weight of their cumulative weight height also has certain security considerations.
Static detection can be divided into three parts to detect the overall structure of the load test, the overall structural stability tests and important components and so on. The overall structure of the load test can be divided into internal and external cold load test load test in two parts. The cold load test is used to simulate the effect on the user during normal use of the device structure training equipment load. External loads imposed on the load test will likely be included in considerations on training equipment. Sometimes in the standard static load only to represent this test. The overall structure of the load test based on H class or S class use category may have different requirements.
Often the load test Rin body weight (100 kg) of a multiple of, the role of the most frequent location of the force in the normal use state, measuring the elastic deformation or permanent deformation. For cantilever type of stress state, shall not exceed the amount of deformation of the cantilever length 1/150, other types of stress state does not exceed the length of 1/100. An external load tests indicated in the manufacturer's maximum load multiple (or other method of calculation), or subjected to the force acting on the position of maximum bending moment, which measure the amount of deformation or damage to observe whether there is the case.
The stability of the overall structure of the human body is usually measured based. The aim is to test the training device in normal use, in the direction of sports equipment or other direction to provide the possibility of destabilizing structures (dump or capsized). Stability testing is common in some cardio training equipment, if the equipment provides a way to adjust the structure, it is necessary to select its extreme cases be tested. Such as structural stability test is based on a treadmill 100 kg testers, at 8 to 10 kilometers per hour rate, and 5 degrees of non-movement of the test direction between +/- 10 degrees in the direction of movement. If the treadmill height is adjustable, it needs to test its maximum height and minimum height adjustable.
Muscle / strength training equipment in common major components are: pulley / rope group, ropes, ropes and belts, barbells, grips, pedals, etc; cardio training equipment in common major components are: handle / vertical bar group, grips, flywheel, free wheel, seat / vertical bar group, pedals or foot platform. Some of the main load bearing components for Class H and S class equipment have different security requirements. For those in the EN 957 in the user directly or indirectly bear the load components specially developed training equipment, depending on its corresponding test methods to enhance their security. Some of these special requirements, such as ropes, belts and chains to prevent breaking, tensile strength should be the maximum possible safety factor of six times.
Fitness equipment dynamic tests include endurance test as well as additional requirements for different levels of precision. Simulate each major endurance test equipment in use state of durability. Almost every test methods are very different because of the equipment and features. Durability tests are usually for use category (H class and S class) may have different testing requirements. Additional requirements for different levels of precision are mainly based on precision grade (A, Class B, Class C) of equipment have varying degrees of accuracy.
With fitness equipment durability testing requirements include: strength training equipment, treadmills, rowing machines, steppers and elliptical machines. In addition to strength training equipment, equipment durability tests are due to the use of categories and have different requirements. Typically the number of tests for home fitness equipment 12,000 commercial type is 100,000 times. The test load and test methods due to different models has a very big difference. Test methods such as stepper and elliptical machine is very close, the biggest difference is the test path (motion path) are different. Motion path elliptical machine is an approximate elliptical path, stepping machine is basically a circular-shaped path, this difference is caused by differences in test equipment design.
Fitness equipment based on the generation of resistance way, there is nothing to do speed training equipment and speed-related training equipment different testing methods also need to be adjusted. Independent of the speed of the training devices are often at a rated load (resistance or power) under test to a fixed speed. Speed-related training equipment places a fixed load test (based on fitness equipment to provide braking power to determine the test load).
All cardio training equipment (EN957 Part 5 ~ Part 9) has the additional requirements of different accuracy classes. For rowing machine, stepper, stair climber, climbing machines, elliptical machines, the additional requirements of different accuracy classes are very similar, they are mainly to provisions for a Class A rating. Comparison of test equipment, power input and power display error value. Test and measurement equipment to display error value should be within +/- 10% (if the test value at 50W following error should be within +/- 5W). The measurement values of the goods shall have at least an average of 10 minutes test time. The measuring device must have a +/- 1% accuracy. At the same time manufacturers should describe the input power to the power display value is calculated in the manual.
Classification treadmill requirements include A / B / C class requirements, test basis, precision measuring equipment, electric / non-motorized treadmill done a very complete definition EN957-6 details please refer to Table 1. In particular exercise bike does not require endurance test, but it is the most rigorous precision on different categories of requirements, the project tested the most. There are different types of brake torque test, long load variability test, intermittent testing, power testing.
In this presentation, we hope to help readers in safety requirements and inspection and testing of indoor fitness equipment on top of this theme can get a complete concept, and therefore deliberately omitted many details. Hope you can use this as a basis for further study of indoor fitness equipment, text or omissions, I hope they feel free advanced industry.
