WHEN YOU THINK OF ISO -
• What part of the world do you think about?
• What products, services or processes do you think about?
• Are ISO standards of value to you or your organization?
• Do you think the US should participate in ISO standards development?
• Do you think the US fertilizer industry should participate in TC 134?
• Do you think your organization should support participation in TC 134?
TC 134 STANDARDS UNDER DEVELOPMENT
• Sampling from a conveyor by stopping the belt
• Mechanical devices for sampling of product moving in bulk
• Determination of ammoniacal nitrogen content - Titrimetric method
• Determination of total nitrogen content - Titrimetric method after distillation
• Extraction of water-soluble phosphates

• Determination of phosphorus content - gravimetric method
• Determination of ammoniacal nitrogen content - Titrimetric method
• Extraction of phosphates soluble in mineral acids
• Preparation of samples for chemical and physical analysis
• Simple sampling method for small lots
