IS 11100 defines the use of properly seasoned bamboo strips free from damage caused by Ghoon (Dinoderus) infestation, rot, charring, or any defects that could affect broom longevity. While the standard primarily focuses on bamboo strips, specific timber species are identified for plug manufacturing, ensuring durability and resistance to pests. Bamboo strips must be split from seasoned bamboo and shaped according to the design shown in the standard for optimal broom performance.
To ensure long-lasting bamboo strips, IS 11100 prescribes that seasoned bamboo must be free from defects and then fully immersed in undiluted creosote oil (IS: 218-1983) for a minimum of five minutes at room temperature. After treatment, the strips should be thoroughly dried before further processing. The strips must also be trimmed as per the specified dimensions to maintain uniformity and protect against decay and insect damage.
According to IS 11100, sweeping brooms must conform to the design and shape illustrated in Figure 1 of the standard, with all measurements provided in millimeters. Each broom should consist of 680 to 850 grams of split bamboo strips to ensure consistency in size and weight, which contributes to effective sweeping and durability.
The standard advises following random sampling techniques as outlined in IS 4905-1968 to guarantee representative samples. For dimensional, non-destructive, and visual inspections, sampling is performed as per Table 1, while laboratory testing follows Table 2. Sample sizes and acceptance criteria vary depending on lot size and maintain an Acceptance Quality Level (AQL) of 6.5% for major defects, ensuring statistically valid quality control.
IS 11100 distinguishes minor defects as slight dimensional deviations and surface finish imperfections, while major defects typically include significant dimensional inconsistencies or structural problems that impair broom function. Samples are examined according to Table 2 for laboratory testing, using AQL criteria for acceptance. Minor defects affect appearance or minor tolerances, whereas major defects compromise structural integrity and overall broom performance.
