IS 11100 - Sampling of Sweeping Brooms (Appendix B)

Key Points:

• Sampling Method:
  Use any appropriate sampling method from IS 4905:1968 to ensure representative samples.

• Sampling Tables:
  Samples must be drawn according to Table 1 and Table 2 (referenced in IS 11100 Appendix B) which specify:

  • Sample size based on lot size.
  • Acceptance and rejection criteria for quality assessment.

• Purpose:
  To assess various quality parameters like broom fiber strength, handle dimensions, and overall workmanship.

Summary of Sampling Procedure:

(Note: Values are indicative; refer IS 11100 Appendix B for exact tables.)

Reference Standards:

• IS 4905:1968 — Sampling procedures for lot inspection.
• IS 11100 Appendix B — Specific sampling guidelines for sweeping brooms.
