We hypothesized that extra costs incurred in meeting the requirements of wheelchair standards are recouped within the life of the wheelchair. We selected standards-quality and non-standards-quality electric wheelchairs of the same make and subjected them to accelerated life tests in a laboratory to simulate 1 year's active use. Expenses and lost time incurred due to breakdowns were monitored, and the costs of upgrading were documented. Our results support the hypothesis, within the limits imposed by the availability of only a small number of makes of electric wheelchairs of recognized standards quality. The significance of this finding is that wheelchair standards can be used to upgrade wheelchair quality in a cost-effective manner.
我们假设，满足轮椅标准要求所产生的额外成本在轮椅使用寿命内能够收回。我们选择了同一品牌的符合标准质量和不符合标准质量的电动轮椅，并在实验室中对它们进行加速寿命测试，以模拟一年的实际使用情况。监测因故障产生的费用和时间损失，并记录升级成本。在仅能获取少量公认标准质量电动轮椅品牌的限制条件下，我们的结果支持了这一假设。这一发现的意义在于，轮椅标准可用于以具有成本效益的方式提升轮椅质量。
