3 General
3.1 Types of Tests
3.1.1 The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
3.1.2 The types of tests to be employed fall into the following general categories:
a) Static load applications;
b) Dynamic load applications;
c) Durability and/or life cycle testing.
3.1.3 The tests described in this standard, other than the specifically identified component tests (i.e., base loading) are intended to evaluate the entire chair assembly, including the base, tilt mechanism, height adjustment device, locking/adjustment mechanisms, seat/backrest attachment, etc.
3.1.4 Each manufacturer’s model or unit type in any configuration shall comply with applicable requirements when tested in accordance with this standard. Only worst-case models need to be tested for a specific unit type. A worst-case condition shall be representative of all models or units of the type tested. If “worst-case condition” is not readily evident, a case-by-case product line analysis by the manufacturer in consultation with the designated testing facility may be necessary, taking into consideration any special attributes, methods of construction, materials, and/or design features, etc.
3.1.5 The test methods included in this standard require the use of fixtures and/or load adapters to perform the tests. Some products and/or constructions may need special test fixtures, load adapters, etc., to perform these tests in a manner that meets the intent of the standard. This is especially true of products with complex articulation of joints, unique motions or adjustments, or non-traditional use of materials. The users of this standard are encouraged to develop appropriate fixtures and/or test variations that more accurately simulate application of loads, etc., for given unique products in a manner that reflects actual use. Fixtures, load adapters, etc., shall not add structure or provide support to the product being tested. Any deviations from the test methods/fixtures or special testing considerations shall be noted in the test report (see Section 3.7). Independent/consumer testing facilities may need to consult with product manufacturers to assure any special conditions are considered during testing.
