What is DHU? How to measure DHU?

SHARE:

Question: I want to know more about DHU in quality control. Can you please elaborate this term?

Answer:
There are two common quality measures used in garment manufacturing 
  • Number of defects and 
  • Number of defective garments found in inspected garments
To understand DHU, first you have to know the term 'defects' in garments and 'defective garment'. To many people these two terms are not completely clear. The terms defect and defective have been explained here


In garment production processes, quality checking stations are set for stopping defects at the source and stopping defective garment passing to the following processes. Normally, checking is done for raw materials, partially stitched garments, stitched garments and finished garments by quality checkers. In checking, quality checker detects defects in garments and separate defective garments from good pieces. Where there is established quality system, quality checker records total number of defects found in the garments checked by her/him in a day and also she/he records the number of defective garments where those defects are found. Quality checking records are summarized and result is presented in DHU.

What is DHU?


DHU stands for Defect per Hundred Units. It means number of defects found or detected per 100 garments. This is also known as DPHU (Defects Per Hundred Units).

DHU value is calculated using following formula.

Defects per hundred units = (Total defects found * 100)/Total garments inspected

Illustration: Assume that a finishing checker checked 250 garments in a day. Checker found 20 defective garments and he recorded 35 defects in those defective pieces. What is the DHU of finishing process?

Solution: By using above formula DHU of the finishing goods is

= 35 * 100/250
= 14

How to measure DHU?

To measure DHU of any process, one needs to record number of total pieces checked and number of total defects are detected in the inspected garments. It is number of defects not the defective garments. One defective garment may have more than one defects. Like a checker found broken stitch, a hole and raw edges in shirt. Here checker found one defective shirt but the defective shirt contains 3 defects.

Once you have record of the following information of a lot you can measure DHU of that lot using above formula.
  1. Total pieces inspected 
  2. Total defects found in those inspected pieces

Following table can be used for data capturing during of the garment inspection.
