    1. Rationale

    This work item addresses paragraphs 7.2 and 7.7 of ASTM-F-2264. The current revision to ASTM F-2264-09 requires the use of a block of wood (6 X 6 X 2 inches) on the deck during the 7.2 Deck Test and 7.7 Dynamic Strength Test. The function of the block of wood is understood as it helps distribute the test loads evenly and prevents damage to the scooter from concentrated test loads from the test weights. The issue has arisen that not all scooters are constructed with flat steel or flat aluminum decks. Some new scooters on the market are constructed with durable injected plastic (or similar matrials) decks. These decks are often not flat but contoured. The use of a wooden block for testing of these plastic contoured decks results in stress concentrations (point loads) at the points of contact, often in as few as 3 places. The use of the wooden block can actually crack the plastic at these contact points due to the unusually high stresses. This type of loading/testing is not representative of actual product use, misuse, and abuse by the consumer for scooters with this type of deck. A wooded block contacts flat steel or aluminum decks uniformly. A similar distribution of load should be required on a contoured deck. The intent of the ASTM-F-2264 is to apply a reasonable test the scooter to verify product safety, quality and durability under reasonably foreseeable use, misuse, and abuse. The proposed amendment to the protocol is to include an option to the current test medium (wooden block) that will be used on non-flat decks. This optional medium would be somewhat pliable and conform to the shape of a contoured deck, but still provide load distribution equivalent to the wooden block. This medium could be a sand bag type device of the same dimensions as the wooden block. The proposed change is as follows: From: 7.2 Deck Test: 7.2.1 Apply a static load of three times the manufacturers maximum specified weight limit, or 600 lb (273 kg) if there is no maximum specified weight limit, to a nominal 6 by 6 by 2in. (15 by 15 by 5cm) wooden block centered between the front and rear axles of the scooter and centered axially. To: 7.2 Deck Test: 7.2.1 For flat deck scooters apply a static load of three times the manufacturers maximum specified weight limit, or 600 lb (273 kg) if there is no maximum specified weight limit, to a nominal 6 by 6 by 2in. (15 by 15 by 5cm) wooden block centered between the front and rear axles of the scooter and centered axially. For non-flat deck scooters apply a static load of three times the manufacturers maximum specified weight limit, or 600 lb (273 kg) if there is no maximum specified weight limit, to a nominal 6 by 6 by 2in. (15 by 15 by 5cm) sand bag or similar medium, centered between the front and rear axles of the scooter and centered axially. From: 7.7 Dynamic Strength Test: 7.7.1 Apply a weight equivalent to the manufacturers specified upper weight limit or, if not specified, 200 lb (91 kg), to a nominal 6 by 6 by 2-in. (15 by 15 by 5-cm) wooden block centered between the front and rear axles of the scooter and centered axially. To: 7.7 Dynamic Strength Test: 7.7.1 For flat deck scooters apply a static load of three times the manufacturers maximum specified weight limit, or 600 lb (273 kg) if there is no maximum specified weight limit, to a nominal 6 by 6 by 2in. (15 by 15 by 5cm) wooden block centered between the front and rear axles of the scooter and centered axially. For non-flat deck scooters apply a static load of three times the manufacturers maximum specified weight limit, or 600 lb (273 kg) if there is no maximum specified weight limit, to a nominal 6 by 6 by 2in. (15 by 15 by 5cm) sand bag or similar medium, centered between the front and rear axles of the scooter and centered axially.
