Toys, clothes and diapers were among a batch of products that failed to meet standards, the quality watchdog spokesman said on Wednesday.

The General Administration of Quality Supervision, Inspection and Quarantine examined 10,473 items of children's products this year and found 644 of them, by 571 manufacturers and producers, below standard.

Fu Wenbiao, deputy head of the general office of the quality watchdog announced the findings at a conference on product quality regarding eight key categories.

The categories were: children's products, stationary, gasoline and diesel for vehicles, timber products, fertilizers, water conservation products and electric cables.

The authority divided children's products into five categories: toys, baby carriages, clothing and shoes and paper diapers. They examined 674 items by 663 producers, Fu said.

Of the 187 items of stationary products examined in 12 provincial areas, the authority found 18 items, by 18 producers, were below standard.

In the gasoline and diesel category, the authority found 20 products were below standards of the 180 examined made by 180 producers.
